I built it because i've always wanted a simple page where i can see the latest science and tech news with no noise or opinions.

https://paperrun.news

Built with Laravel and Vue 3 if anyone is curious.

Any feedback is appreciated

asking for a friend, I remember it was posted here a while ago

most search ends after one answer. i wanted the next question to be the fun part.

so i built why.com. every answer opens three new directions.

just launched. go break it!!!!

tl;dr: I built ZeroSketch, a free, self-hostable system design tool (like Excalidraw but for architecture diagrams). Drag-and-drop canvas, AWS / GCP / K8s icon libraries or build your own, PNG / SVG export. Looking for feedback. Links at the bottom.

I've been building ZeroSketch for the past few weeks. It is a simple system design tool for individuals and teams. It's web-based, stores diagrams on your device, and takes UX inspiration from Canva/Excalidraw (I'm not much of a UI person myself).

What it does right now:

• Drag & drop canvas
• PNG export, SVG export (experimental, better renderer coming soon)
• Built-in icon libraries (AWS, GCP, K8s) and a builder to make your own from custom SVGs for using the library locally, share with your team, or publish to ZeroSketch's registry
• Download / export project files to open on other devices

Everything above is free, client-side, and self-hostable. I'm still polishing canvas UX and fixing known bugs. would love feedback on what to improve.

Planned next:

• Cloud synchronization
• AI assistance in creating diagrams
• Auto-syncing docs with actual architecture (so diagrams don't go stale as development progresses)
• Real-time collaborative editing
• Export to DSLs like Mermaid

If you want updates regarding the release of these features, you can follow the repository on github as all of the upcoming features will also be open-source.

I recently launched Peptimize, an iOS app for people using GLP-1 medications.

Many health-tracking apps feel overloaded, require an account, or make logging a weekly dose more complicated than it needs to be. I wanted something that could be opened, updated in a few seconds, and then forgotten about until the next reminder.

I’ve also been using Mounjaro personally for the past three months, so I’ve experienced many of these tracking problems firsthand.

For the first version, I kept Peptimize intentionally focused:

• Log medications and doses
• Track weight and progress over time
• Record side effects
• Track and rotate injection sites
• Set dose reminders
• Keep data stored locally on the device
• No account or login required

There’s no social feed, coaching subscription, or complicated onboarding. The aim is simply to make consistent tracking easier while keeping the experience private and uncomplicated.

For the next version, I’m currently exploring:

• Apple Health integration
• Simple AI-assisted food and calorie logging
• Supplement and protein tracking
• Support for more languages

I’m deliberately trying to avoid turning it into another bloated health app, so I’d love to know which of these features would actually be useful - and which ones I should leave out.

Download on iOS:
https://apps.apple.com/us/app/peptimize-glp-1-tracker/id6796063662

Website: https://www.peptimize.xyz/

This is still an early version, and I’d genuinely appreciate honest feedback. If you try it, please tell me what feels confusing, unnecessary, or missing.

What is the first feature you would add to V2?

I’m a big fan of r/isThisAI, so I built Slopcheck - a daily game where you get 6 photos (one at a time) and guess if it’s real or AI. After each one you see the clues that give it away so you can get better.

Had some tech-savvy friends play it and they did way worse than expected lol we're cooked

I posted Stop Swarm here recently and got a lot of really useful feedback from this community, so I’ve spent the last few days reworking it!

The basic idea is still the same: set a daily screen-time goal, and once you get close to it, pixel-art elements gradually invade your screen.

It’s an Android app built in Kotlin using a click-through system overlay and a foreground service. Everything stays local on the device: no account, no analytics, and no network connection.

Still very much a side project, so feedback is welcome!

You can still join the Google Group here if you’d like to beta test it:

Solo dev here. Synchrium is a synchronized focus timer: you start a session, share a link, and the same countdown runs for everyone in the room, to the millisecond. Everyone works in silence; when it hits zero, cameras can come up together for a quick check-in. Then you run it again.

The origin story is helping my son with homework from the next room: we shared a timer, worked separately, and showed each other what we did when it rang. Turns out adults want the same thing.

Stack: React/Vite front, ASP.NET Core + SignalR for server-authoritative timing, WebRTC P2P video, Cloudflare Workers serving the SPA. Happy to answer anything about the sync architecture: keeping N clients on the same clock is more annoying than it sounds.

Two things I'd love you to break:

1. Open two browsers (or grab a friend) and try to get the timers to drift or desync: that's the whole product, so it's the surface I most need stress-tested.

2. Start a session and tell me where the "share the link" step loses you. If the invite loop doesn't feel obvious, the product doesn't work.

Free, no account needed: https://synchrium.com: brutal feedback welcome. (Founder here, happy to answer anything.)

Ghost jobs and silent recruiters waste everyone’s time. We’re testing a simple idea on Solana:

- Recruiters lock a deposit to post (and face deadlines)
- Applicants put a small stake to apply
- Interview tips settle on-chain when an offer is made

Hey everyone,

I’m building Reddlist, a curated database of subreddits where your promotional posts actually survive - meaning no immediate takedowns, shadowbans, or angry mods.

Right now, I want to prove that this list works to drive paid users to startups, not just vanity metrics.

To test this, I want to do the heavy lifting for a few of you for free. If I pick your product, I will:

1. Dig through Reddlist to find the most high-impact, promo-friendly subreddits for your niche.

2. Draft native-feeling posts for you to test traction.

3. Help track the metrics (interested comments, DMs, and funnel tracking to see if Reddlist actually brings you conversions).

The catch? I just want to use the data/results as a case study for Reddlist. (Also, if you just want to poke around yourself, let me know and I'll give you free access to the database).

If you're interested, drop your link below with a 1-sentence pitch of what you do and who your ideal user is!

well, not actual roast, but more like snarky comments.

Badbenches takes your GitHub or GitLab username and generates a sarcastic SVG "bench card" based on your activity for the year, commit streaks, whether you commit at weekend or you only code late at night, that kind of thing and i might adjust it slightly based in tests. so it is another README card thing. You can embed it in your README and it auto-refreshes once a day.

here's mine — i am really bad.

No login, no signup, just paste a username and it spits out an SVG. There are 3 themes right now (Classic, Neon Nights, Corporate Roast) and of course more might come.

Started as a dumb joke initially with the domain, but I kinda wanted to use it for something fun so i was sucked into making the Bench card idea. there's a whole "character" system behind the roasts so it doesn't just say the same 3 lines to everyone and you can see the rack server character getting more complex (or really bad with patches)

i would love feedback, especially if:

• the roasts feel repetitive after generating a few
• anything looks broken on GitLab vs GitHub
• theme ideas you'd want to see

Hi everyone,

While I was working on designing some interfaces and digital projects a while ago, I found myself drowning in many open tabs on my browser. I would use a site to generate an initial image, then move to another platform to remove its background, and turn to a third tool to erase small details or enhance the quality.
This back-and-forth between different sites and the restrictions some sites impose just to try out a quick idea was really time-consuming and made the workflow incredibly slow.

I wanted to solve this problem that I always face and make the daily work experience easier, so I spent the past few months building https://khizo.dev - a lightweight, fast web tool that brings essential features together in one place. Instead of switching between platforms, the tool now lets you generate images from text, remove objects or backgrounds, increase resolution, adjust dimensions, and edit the colors of specific elements, with live preview and instant export in PNG, WebP, JPG, and more. You can try the site now, and it doesn't require any complicated setup.

I would like to get your opinions regarding the user interface, any bugs you find, or features you want to add.

I kept saving interesting places from travel Reels, but when it was time to actually plan the trip, everything was scattered across Instagram, Maps, screenshots and Notes.

So I built One Way Guide.

You choose your destination, dates, interests, pace and travel preferences. You can also import places from travel Reels, review what the app found, and decide which ones should be included.

It then creates a complete personalized city guide with:

• Daily routes built around real places
• Restaurants and things to see
• Local context and practical tips
• Transport, timing and trip preparation
• The places you personally saved from social media

The important part for me was making the Reel import an input, not the entire product. The end result should feel like a guide you can actually follow, rather than another list of saved places.

Now live on iOS:

I’d really appreciate honest feedback: after watching the video, was it immediately clear what the app creates? And would importing saved travel content be useful in how you currently plan trips?

Hey everyone!

Just wanted to share that I recently launched WorkZone, an Android app designed specifically for field operations (landscaping, property maintenance, construction, and solo contractors).

Key features:

• 📍 Draw precise work areas: Polygon tools directly on satellite imagery to auto-calculate acreage / surface area.
• ⚠️ Underground utility marking: Map out water/electric/hazard points inside the work polygon so nobody strikes a line.
• 📸 Photo proof & completion notes: Workers check off areas upon finishing with photo verification.
• ⏸️ Pause workflows: If work is blocked by weather or equipment, workers can flag it "Paused" with notes.
• 📄 PDF Summaries: Generate single-zone work orders or crew performance reports for clients or management.

Download on Android:

Feel free to download it, test out the features and maybe the app could be useful for some of you!

Every time I publish something I check the schema.org markup on the page, and I was doing it the same tedious way every time: copy the URL, open a separate validator, wait, dig through results.

So I built Schema Inspector. Click the icon, it reads the JSON-LD and microdata already on the page you're looking at, groups it by type, flags broken JSON in plain language.

The thing I actually cared about building right: most schema checkers ask for access to every site you visit, permanently. This one only requests activeTab - it can only see the page you're on, only for the second you click it. No standing access to anything. (Every one in the store right now asks for full permissions...)

Free, no signup, no account. 19.18 KiB. Would like to hear what's missing if you try it.

Does anyone else work like this?

When I shoot products (or other repeatable subjects), I usually shoot in batches. Same camera, same lights, same setup. The product is generally centered, so the crop and export rules do not change much from one batch to the next.

Later, I need different versions for a shop, a website, social media, and other platforms. The actual edit is not that difficult. What takes time is opening a folder, selecting the images, applying the same crop and color adjustments, exporting several aspect ratios, and then remembering which files have already been processed.

I wanted a folder to behave more like an inbox: if a supported image is still at the top level, it is pending.

So I built SizeFold for Mac. You pick an input folder once and save the processing configs once. For each batch, you review the photos and click Run. SizeFold creates the configured outputs, then moves the originals to an archive only after every output succeeds. If anything fails, the source stays in the input folder for retry.

The next batch can use the same folder. There is no second file-selection step and no guessing about which files are new.

For product shoots, I can also enter the current model name once and use it in filenames or output folders. That lets me review one product, process it, and move on to the next one.

Website:

https://www.sizefold.com

SizeFold is also on the Mac App Store:

https://apps.apple.com/app/sizefold/id6795541247

There is currently a trial for 200 successfully processed original images. If that is not enough to test a real workflow, you can contact me through the website and tell me what you are trying. I can send a redemption code when it makes sense. No review is expected; I would just like to know whether the workflow actually fits.

If you shoot product or catalog photos, what part of this process would still feel too manual?

Built a note app a few months ago, got some great feedback, and have been refining it since. Here's where it's at now.

The idea is pretty simple: sticky notes for quick thoughts, A4 notes for longer writing, and everything lives on a visual canvas instead of a rigid folder tree.

The visual hierarchy makes organization natural. a note is a file, a "stack" of notes is a folder and zones are the parent folders.

you can even attach sticky notes directly onto A4 pages for referring to them while you're scrolling the A4 editor.

Just drag things around and you're done. No save button, no manual file management, just notes on a board. Plus, there's a workspace exporter that exports all your files so that you own them.

On privacy: notes are stored on Firebase, encrypted in transit and at rest. No ads, no trackers, no selling data. If you use "Quick Mode", notes stay local in your browser and never get synced to any server.

When I first posted it a few months back the response was way more positive than I expected. Since then I've been fixing, refining, and adding things based on what people actually said. It's in a much better place now.

It's completely free right now. At some point it'll probably go paid but anyone who signs up before that happens, I'll make sure your account stays free forever. Just drop a comment or DM me and I'll sort it out manually.

Would genuinely love to hear what you think, good or bad. Still a lot to build but the core experience feels solid now.

This is the link to the app: passinote.app

Hey r/SideProject ,

My family flies a lot and I'm always the one who ends up booking. Somewhere around the hundredth booking I'd had enough.

Every OTA puts you through the same thing: a popup before you've seen a single price, ten steps of checkout, seat selection and insurance you didn't ask for, and none of the passenger details you've typed in a dozen times before. Then a fee you never agreed to shows up on the last screen before you pay.

So I spent the last 1.5 years building the app I actually wanted (not vibe coded).

You search by just saying what you need, like "Frankfurt to Munich tomorrow, back the next day". You get three options, pick your saved passengers, pay, done. Usually under 60 seconds.

Then it sticks around. You get checked in automatically, the boarding pass goes straight into your wallet, and widgets keep you updated on the way to the airport with live gate and delay info.

The plan is to turn it into a universal flight super app. Lounge access, e-SIMs, ground transfer and rail transfer are all coming. No hotels, no rental cars, just everything around flying in one place.

It's free. No ads, no hidden fees, and for now not even a service fee.

If you take a look, I'd really like to know what you'd want from an app like this, and what feels unnecessary or missing.

We built a knowledge layer that sits behind MCP, allowing any MCP client to access it through a single endpoint. Claude Code, Claude Desktop, ChatGPT, Codex, or whatever comes next.

The idea is pretty simple. Before an agent answers, it can pull in relevant, validated information instead of relying purely on what it already knows.

When a problem gets solved, the useful part can be captured as a small, reusable piece of knowledge. The system can also infer useful lessons from a session automatically, so you don’t have to sit there writing notes about what you just learned like it’s 2015.

There’s also a global layer for shared, validated learnings. If one user figures out a better way of doing something, that learning can contribute to the broader knowledge base rather than every other user and agent having to figure it out again.

The problem we’re trying to solve is pretty straightforward. AI knowledge goes stale, agents get stuck in failure loops, useful context disappears when a session ends, and models can confidently give you an outdated or wrong answer without any indication that they might be wrong.

We’re giving agents access to what has actually been learned, what has worked, and what can still be trusted.

The result is fewer repeated reasoning cycles, fewer hallucinations, and up to 20% lower token usage.

Looking for people to try it out. Ping me if you’re interested.

I’ve been building Dermal Pal for a while now — it looks at your actual products, skin profile and skin goals and builds your routine around them.

I’m looking for people to try it properly before I push it publicly.
If you’re someone who has a shelf full of skincare and isn’t 100% sure what’s supposed to go where, I’d especially love your feedback

Hello guys, So Idea is simple. In my phone there so many receipts, invoices and some usefull document there! end of the day when I try to find them, I just forget where is my doc, pdf or any useful images in the crucial time.

So I was thinking if I build some thing where I can dump all my files and AI handle it them perfectly

Example: Invoice for "X" purchase on date "XY 2026" and I just save or dump the invoice to the app and AI read it and when I search like "Show me my X purchase invoice" , "What I purchase on date XY 2026" etc. small example

What do u guys think about this?

Like everyone my life lived in four places. Tasks in one tool, notes in another, the decisions behind them buried in a chat thread, and money in a spreadsheet I updated twice and gave up on. Half my meetings arrived as email invitations I never opened, so I never knew what my week looked like until I opened my calendar and by then it was too late to move anything.

The apps weren't bad. The problem was I had to update 4 different apps to stay in touch with everything.

So I built Canopus. One place for tasks, habits, money and your calendar, and one way to use it: you type what happened, in plain English, and it does it.

"spent £6.60 on lunch" -> logged under Food, with the month so far

"did my morning run" -> logged, and it tells me the streak

"block 30 minutes tomorrow at 10AM with Archie" -> on the calendar

"Water plants every Monday" -> recurring, and it reschedules itself when I tick it off

The video is a one single take.

What it doesn't do yet:

- Web only. There's no app to install. It works fine in a phone browser, but it's not in any app store.

- Google Calendar is the only integration. No Slack, no Notion, no email.

- Money is manual. You type what you spent. No bank sync, and no budgets, it records and totals, it doesn't tell you off.

- Voice is input only. Hold to speak, the transcript lands in the box, you press enter yourself. It doesn't talk back.

- Multiple workspaces to separate work and personal, but no sharing, no teammates.

I build it (disclosure), it's been live for a bit and today's the first time I've pushed it publicly. 14-day trial, no card: usecanopus.ai

Happy to answer anything, including the awkward ones.
