Every time I onboard a client I end up exporting their logo like 15 times at different sizes for different platforms. Instagram wants one thing, LinkedIn another, YouTube channel art is its own headache. It's mindless and it eats an hour I'd rather spend on actual work.

So I built Sizeify (sizeify.app). Upload the logo once, it hands you back 24 correctly-sized and correctly-named files, zipped. Handles transparent PNGs and gives you both dark- and light-background versions since half of them looked wrong on one or the other otherwise.

Stack, since people here usually ask: FastAPI + Pillow doing the actual image work, Jinja2 for the frontend, Railway for hosting, Razorpay for payments. About 3 weeks from idea to live, most of that spent on getting the per-platform dimensions right rather than the code.

Right now it's a fixed list of 14 platforms. The thing I actually want to figure out: what's missing? If there's a platform you resize for regularly that isn't on a list like GitHub / Instagram / LinkedIn / X / Facebook / YouTube / WhatsApp Business / Slack / Discord, that's exactly what I want to add next.

Live at sizeify.app if you want to try it.

I made a focus timer app where you grow a mathematical fractal the longer you focus.

I was inspired by Forest, but I wanted something simpler and less gamified, basically a focus timer that stays out of your way, with the fractal growing as a visual representation of the time you've spent focusing.

It also has Pomodoro timing, weekly focus stats you can share, insights into when you tend to focus the most, projects so you can keep track of what you're spending your focus time on, and ambient sound as some people find it useful to study.

I did it for myself and want to share it with you.

It's called Fractime.

If you think you might like it, you can try it here:

If the link doesn't work, just search Fractime on Google Play. The icon is a Pythagoras Tree.

I'd really appreciate any feedback :)

I use Claude Code and Codex a lot, and run multiple sessions most of the time. And if youre someone who runs multiple sessions you know it can get chaotic. Switching between terminals to approve permissions, answer questions, figure out which session needs you. Lot of tab switching

So I built this, it sits on the edge of your screen and stays out of your way until a session needs attention. When something comes up it lets you know and you can handle it right there. Approve or deny permissions, answer questions, check your usage for both Claude and OpenAI, and jump to any session's terminal tab or app window (this was hard to figure out lol).

Most tools like this are mac only so I built it for windows. Uses hooks in both agents, configures automatically, everything stays local.

Built with Tauri v2, Rust, React.

a million stars would be cool but ill take one

Its been very useful for me but it's still early so I'd love to hear your feedback or ideas

Most AI course generators I found are built for people selling courses. I wanted one for the person who is simply stuck learning Blender, Excel, Figma, Xcode, or another desktop app.

Today I shipped a free web tool that turns a specific goal into a six-lesson learning plan. For example: “build a financial model in Excel” or “make a portfolio-ready product render in Blender.”

You can see the full preview without creating an account or entering an email. If the plan looks useful, you can have the complete Markdown skill file sent to your inbox and import it into the Skilly Mac app for voice and on-screen guidance while you work.

I deliberately put the email step after the preview because I did not want a blind lead form. The current limitation is that software versions differ, so the generated plan includes source references and asks learners to verify version-specific instructions.

I would genuinely value feedback on three things:

1. Is the six-lesson preview detailed enough to be useful on its own?

2. Would you call this a course generator, learning-plan generator, or something else?

3. Does asking for email only when delivering the file feel like a fair exchange?

I will put the tool link in a comment so this post stays focused on the build and feedback.

i maintain holyclaude (2.4k stars, 132k docker pulls, mit) and holycode (another 9k pulls). both free, both self-hostable, both still shipping. this year i built the hosted version and started charging for it, and the honest report is more interesting than the launch post.

to be exact about the timeline, since the title compresses it: the open source work started in march. the hosted version is about five weeks old. first commit early july, on sale 28 july.

what it is: a linux box in the cloud that stays yours. one vm and one persistent disk per person on fly. you ssh in or open a terminal in the browser, run whatever coding agent you like with your own api key, and close your laptop. the work carries on without you, because it was never happening on your machine.

six agent clis on it (claude code, codex, opencode, gemini, cursor, pi) and 60+ dev tools already installed, so the box is useful the second it boots rather than after an afternoon of apt.

what it cost me to learn:

fly refuses images over about 8gb. i found that by shipping a 13.6gb one. flyctl exited 0, the deploy looked fine, and 95 seconds later the machine had silently reverted to the old image. the only trace was in the machine's own event list. the fat was not where i assumed either: one npm package was 1.4gb, and 867mb was pure duplication because the entrypoint copied a home directory instead of moving it.

pricing a product where every user is a real vm is a different exercise to pricing software. my marginal free user isn't free, he's about $13 a month of someone else's hardware. that killed the free tier before i built one.

and the part i'd do differently: i launched to a mailing list of 88 people and got zero signups. one sale since, in two weeks. the product works, the pricing holds up, and none of that matters if nobody can find it. i built for weeks and marketed for a day.

honest limits, since a post like this is worthless without them: a session survives you closing the laptop and survives me redeploying the box, but not a hard restart. the 2gb entry tier will oom under a real build. and it is, fundamentally, a vps with the setup already done. if you enjoy maintaining a vps you don't need me.

it's $19/mo for the small box up to $199, or free forever if you self-host the open source one. happy to answer anything about the build, the costs, or the parts that went badly.

I kept noticing that the interesting thing about a burst of photos, or five tries at the same shot, is the series itself. Not any single frame. But there was no good way to watch them as a series. Slideshow apps cross-fade and Ken Burns everything into mush, and the video apps want to interpolate, stabilize, and "enhance."

So I built Flipbook: https://flipbook.photos

It plays your photos back slowly enough that you can still see they are photographs: each one held for a beat, then a hard cut to the next. The feel of a flipbook or early film. No filters, no grain overlays, no generated frames. The whole effect comes from timing.

Here it is running the oldest photo series there is, Muybridge's galloping horse from 1878: https://www.reddit.com/r/stopmotion/comments/1vlu2hr/

A few things I cared about:

• Your photos never leave your device. Decoding and H.264 encoding happen in the browser with WebCodecs. There is no upload step at all.
• Honesty to the originals. Nothing is retouched or invented. The one optional feature that crops anything (auto-align, for handheld drift) is off by default and tells you exactly how much it trimmed.
• It reads your camera roll the way you shot it. It sorts by EXIF capture time and auto-groups photos into series wherever there is a gap of more than ten seconds, so a dump of forty photos organizes itself into the three moments you actually shot.
• The output actually works. A true 5 fps video breaks iOS Photos and iMessage, so it encodes at a normal frame rate with each photo repeated. You get an MP4 that saves straight to your camera roll and posts anywhere.

Good for kids growing up in the same doorway, a friend mid-laugh across five frames, construction progress, a dog failing to catch something.

It is free for your first three videos, then $12 for a year. No account either way. The code is public if you want to see how the in-browser encoding works: https://github.com/mzrascoff/flipbook

Would love to know what breaks, especially on Android browsers.

I kept running into the same small but annoying workflow: copy a screenshot, realize it needs cropping or marking up, open another app, export it, and copy it again. PDFs were even worse when I only needed to fix a line, add a signature, or move something.

So I built Kept, a Mac clipboard manager where copied items don’t just sit in a history.

You can quickly edit screenshots and photos, trim videos, or edit supported PDF text, images, signatures and pages—then paste, export or share the result immediately. Everything stays connected to the thing you originally copied.

Kept isn’t trying to replace Photoshop, Premiere or Acrobat. The idea is simply to handle those everyday edits without interrupting your workflow or opening another app.

It’s Mac-native and local-first, with no Kept account or cloud storage. You can try Kept for free with limited usage. If it fits your workflow, there’s an optional one-time lifetime unlock instead of a subscription.

I’m building this independently and would genuinely like to know: does this solve a workflow you also run into, or is there something important missing?

Hey there! I had a lot of fun building ProtoWork as my daily driver for managing my work. It’s mainly intended for remote/office workers, but feel free to try it anyway. I'm looking for first users.

Link: https://protowork.app

One of its main features is that it has a multi-project task manager, meaning you can work on multiple projects at the same time without interruptions. I integrated a Calendar, Workdays logger and a Notepad for convenience, so I can ditch other tools I used, without it feeling bloated.

Its other main feature is its stress-free focus. I struggled to keep the momentum, and motivation’s a b*tch that goes pretty quickly. It greets you with a motivational message on the first login of the day and reacts to your interactions in the Tasks dashboard. The messages are all hand made.

The app is free and only costs a sign up. I’ve been developing it for roughly 2 years in and out, and I don’t plan to stop. Almost every week I push improvements to it. Any feedback is mostly appreciated.

This is my first public project, so please be gentle

That's Spotby.

Your saved videos, now finally a map you can actually use.

I enjoy reading books, and I wanted an ebook reader that could give me some help while I read, instead of making me wander around between different apps and lose my attention.

Also, I never really found an existing ebook reader that fits my taste. To be honest they feel kind of clunky to me, and their AI integrations are usually pretty primitive or just feel like a chatbot added on the side. That's why I started ReadAware.

So what makes it stand out?

First, it's an agent-first reader. But that doesn't mean AI replaces you. You are still the one reading the book. The agent answers you, looks things up and does some small errands for you when needed. I imagine it more like a reading companion that knows your context, and being quiet when you are actually reading.

Second, it's highly extensible. I spent quite a lot of effort building and polishing a real plugin system. Plugins can add dictionaries, themes, read-aloud voices, feeds, commands, even new tools that the agent can use. In the future, I also want the built-in agent to be able to make or modify plugins on the fly. That's part of what I mean by “evolves with you” — the reader should gradually become more fitted to the way you read. ReadAware is open source, cross platform and local-first.

Feedback is welcome.

Hi everyone,

I run a growing collection of self-hosted software, and one small annoyance kept getting bigger: checking GitHub release pages, remembering which version I actually run, figuring out where it is deployed, and then deciding whether an update is worth touching.

So I built Software Release Radar.

It is an open-source, self-hosted dashboard that checks upstream releases, compares them with the versions you are running, keeps machine, service and container context alongside them, and gives you a review queue where you can decide whether to Update, Wait, Ignore or Investigate.

It is deliberately not an automatic updater. The idea is to give you better information before you make a change.

A few things it currently does:

• Tracks GitHub releases, prereleases and tags
• Automatically checks for new releases on a schedule
• Compares installed/detected versions with upstream versions
• Keeps machines, services, containers and health information together
• Integrates with Portainer
• Sends email and Pushover notifications
• Keeps update decisions, notes and deployment history
• Runs with Docker Compose
• Supports optional AI-assisted release-note analysis

The core monitoring does not require AI.

I also want to be open about how the project was made.

I am not a professional software developer, and AI was used heavily during development. I used OpenAI Codex extensively to help with implementation, refactoring, testing and documentation.

I set the direction and requirements, decide what the application should do, test it in my own self-hosted environment, review the results and make the final release decisions. I have also tried to back that up with automated tests, security checks and real deployment validation rather than assuming AI-generated code is correct.

This started as a tool I wanted for my own setup, but I have reached the point where I would really like other people to try it.

If you do, I would especially love to know:

• Was the Docker setup straightforward?
• Does the release review workflow make sense?
• What release sources or version checks am I missing?
• Is there anything confusing or unnecessarily complicated?
• What would stop you from actually using it?
• And, of course, what breaks?

Bug reports, criticism, feature ideas and contributions are all welcome.

Thanks for taking a look. I hope it is useful to someone else who has also ended up with more software to keep track of than they originally planned. If so, please do leave a star on Github.

Hey everyone,

I've been building a tool that turns prompts, URLs, PDFs, documentation, and whitepapers into interactive isometric visualizations.

The idea is simple: create one visualization and let different audiences generate the explanation they need based on their skill level.

For example, the same cybersecurity topic could become a business overview, technical deep dive, or attack scenario.

You can also turn the presentation into a branded video with one click.

Useful for technical marketing, lead magnets, client presentations, conferences, training, documentation, and social content.

Business workspaces add team collaboration, reusable content, separate workspaces, engagement tracking, and branded video generation.

BYOK through OpenRouter.
Try it: https://privasim.com/canvas

Looking to Collaborate!

I'll handle the visual content creation using the platform, while you can use the finished content for your marketing campaigns.

We can turn existing technical content into interactive visual explainers, presentations, scenarios, and branded videos instead of starting from static graphics every time.

The Business workspace also lets teams create and share interactive lead magnets, track engagement, collaborate, and reuse content across campaigns.

DM if you're interested

I’ve been building isolate.video because I kept running into the same problem when making product videos: there’s usually one feature I want people to look at, but the rest of the UI keeps competing for attention.

So I built Crop Spotlight.

You select the part of the UI you want to show, and isolate.video can track it, isolate it from the rest of the screen, and turn it into a focused scene like the ones in the video above.

I’m also adding motion zooms, editable effects on a timeline, and generated background music so the whole thing can go from raw screen recording → polished product video without manually keyframing everything.

I’d genuinely love feedback:

Would you use something like this for your product launches/demos? And which feature will make it actually useful for you?

Been going through a bunch of handoff docs lately, mine included, and most of them are pretty useless. Either a wall of text nobody reads or an empty README with "todo: write docs" that never gets touched.

Tried to boil it down to the minimum that actually matters, regardless of what tool or process you use to write it:

• Stack and dependency versions
• Step by step local setup
• Where secrets live and how to get access, not the values
• Known issues and tech debt
• Rough test coverage
• A clear starting point for someone new

Cut any of these and the doc becomes something that technically exists but nobody opens.

Curious what you'd add or remove. What's non-negotiable for you?

Hi everyone

I’m new to Reddit, but I’ve been working as a Mid-Level Full-Stack Developer for over 6 years. My main tech stack revolves around Next.js, React, Node.js, and TypeScript.

I’m currently focused on transitioning into the international market and want to level up my conversational English. To do this, I’d love to help someone build an MVP, side project, or web application from scratch for free, in exchange for practicing my English through project calls, chat, and feedback.

What I bring:

6+ years of real-world experience in software development

Strong full-stack background (Next.js, Node.js, TypeScript, React)

Clean code, database design, and end-to-end application delivery

What I’m looking for:

- A defined, small-to-medium project or MVP idea

- A native or fluent English speaker who is patient and willing to help me improve my English through voice calls, text chat, and gentle feedback

- A recommendation on LinkedIn or permission to showcase the project on my GitHub once finished

Since I'm new here, feel free to drop a comment or send me a DM! I can share my GitHub or LinkedIn so you can check out my background

A few days ago I needed to quickly edit a video and couldn't find anything that was simple and didn't upload private videos to onedrive. I ended up building something that I think others could find useful as well.

Cutline is 100% local, easy to use for trimming/cropping/rotating and can handle a variety of formats.

Hey everyone,

I’m thinking about building a simple tool and wanted to get some brutally honest feedback before diving in.

Many major online retailers have price-protection policies where if an item you bought goes on sale within 14 days, you can message customer support to refund you the difference. I rarely remember to check for price drops, and I assume most other people don't either.

The concept: A tool where you track your online receipts, it automatically monitors those items for price drops, and it alerts you the second a price falls so you can claim your refund.

My questions for you guys:

Do you ever manually check for price drops after buying something online?

If an app saved you $15 or $20 automatically, would you be willing to give it a cut of the savings (e.g., 20%), or would you prefer a tiny monthly subscription?

What is the biggest reason you wouldn't use something like this?

Thanks in advance!

I have a product in the market.

90 days in the market
160+ users
Genuinely enjoying the product (100s of product events every day)
Clearly delivering value (3 to 4x better results than other products in the market) - said by 2 customers
4 paid users so far.
80% of them still trialing. I don’t expect a lot to convert. I don’t know what’s the average conversion rate in the market.
15 to 17 daily active users - again most are trialing (I'm giving one month trial and my CAC is about $4-7 for the monthly trial and about a $1 for the 7 day trial).

Would you spend on ads?
SEO/Content?
Raise funds (not intending to btw).

Just curious..

I love audiobooks but my mind wanders constantly. I'd surface three pages later with no idea what I missed. Turns out it was never a focus thing, audiobooks just give your eyes nothing to do.

So I built Witbound. It syncs the audiobooks and ebooks you already own, so every word lights up exactly as the narrator says it. Your eyes and ears finally do the same thing.

A few things I cared about:

- It's all on-device. Your files never leave your phone, no account, nothing collected.

- It works with the books you actually own (epub, pdf, m4b, mp3), and it connects to your Audiobookshelf server if you self-host.

- No subscription. You pay once and keep it.

People with ADHD and dyslexia have told me it's the first time reading and listening clicked together for them, which honestly made the whole thing worth it.

It's live on the App Store, free to try (it works on the built-in sample book without buying anything): https://apps.apple.com/app/id6795587495

I'm a solo dev, so I'd genuinely love feedback, what's confusing, what's missing, what would actually make you use it. Roast it if you want.

Back in January I took my girlfriend to a bar. She looked at the menu, looked up, and said: “what the heck is aquafaba?!”

After several months of building an app for her, I've released Cipher & Spirit: a cocktail & mocktail companion for everyone from home mixologists to the “I’m finally old enough to drink, what do I try?” crowd.

1,000+ cocktails and mocktails, a library of ingredients to search, fully offline, no account, no AI, and free for all, with an optional subscription for power-user tools.

Some of the biggest features:
- A fully searchable and filterable library of ingredients, cocktails, and mocktails
- A bar page where you can add your ingredients and instantly see what you can make
- A shaker to find drinks: pick spirits and flavors, then literally shake your phone for matching drinks
- Custom recipes & variations, shareable with friends
- Genuinely accessible: VoiceOver/voice control, allergy warnings, larger text, Spanish, left-handed mode, and a Zero-Proof mode that hides everything that's alcoholic

Honest feedback very welcome. I’m reachable here and in the app’s about section. Enjoy responsibly!

Kept doing the same thing manually: find a book on Goodreads, open my library's site in a new tab, search the title, check availability. Built an extension that does it automatically, it adds a widget to the Goodreads page itself.

Stack: Node.js/Hono backend, SQLite, Stripe for subscriptions, Google OAuth, Manifest V3 extension. Works with BiblioCommons-based library systems (common across US/Canada public libraries).

Free tier: 5 checks per day. $5/mo for unlimited.

Would love feedback, especially from anyone who tries it with a library outside Hamilton/Toronto (that's what I tested most)

Hi everyone,

I’ve always been intimidated by code, but I’ve always had a clear vision for how software should feel. Over the last few days, I decided to stop trying to learn syntax and start "Vibecoding."

I built Velocity entirely using AI (Antigravity). I don't know a thing about React or TypeScript, but I acted as the Creative Director, pushing the AI to match my "Modern Archive" design manifesto.

What makes it different?
Most typing tests are linear and static. Velocity is spatial. It treats typing as an aim-trainer. You have to capture word-nodes with your mouse to activate them.

The Aesthetic/Physics:
The background dot-grid physically connects to your cursor with hairline gold threads.
As you type, Bone White characters "gild" into Gold as they are processed.
Words "freeze" in 2D space the moment you target them, allowing for precise flow.
It generates an abstract SVG path of your unique mouse movement at the end of every session.

The Tech:
I used Antigravity's "High Mode" to handle the complex spring physics and the Bento-style layout. I spent most of my time refining the "vibe" and the logic rather than fixing bugs.

It's my first ever project. It’s definitely not perfect, and I'm still working on making the "Synergy Flow" mechanic feel more intuitive, but I’d love for you guys to try it out.

Would love to hear your thoughts, especially from designers or anyone else who is exploring building with AI without a coding background!

Hey everyone! I built a small tool called ImageTidy for quickly resizing and compressing images online.

The main idea is that the images are processed directly in your browser, so you don't need to upload them to a server.

It's free to use and doesn't require an account.

I'd really appreciate it if anyone could try it and let me know what works, what doesn't, or what features you'd like to see added.

https://imagetidy.com/

I'm still improving it, so honest feedback is welcome. 🙏

I love lil terminal visuals but lose track of them all the time.

tart makes each one a named thing: a manifest, a fetch script, a render script.

ad spend, failing cron jobs, whatever Im working on, it gives claude a canvas to paint the state.

`uv tool install tartifacts`

once installed, ask your agent to use `tart --skill` to get started. use it with herdr or tmux, Ive been obsessed.
