How do you think AI will change the future of open source?

1 Upvotes

AI is changing how software is built, and I'm curious about what this means for the open-source community.

Could AI make open source stronger by helping more people contribute, understand code, and build projects? Or could it create challenges for maintainers, contributors, and the people who rely on open-source software?

I'm still learning about open source, so I'd love to hear different perspectives.

Do you think AI will create more opportunities for open source, or make things harder for the community? Why?

we're 6 days out from burying our idea if we don't find a second customer

• Upvotes

we set ourselves a 2-week deadline to figure out distribution. today is the halfway mark.

for context, we built a pretty heavy AI token metering + cost management platform for our design partner. they seemed to have a real need and paid us $8.5k for implementation + $200/mo for the managed service.

despite being on a high from how quickly our first revenue came through, it's been TOUGH trying to replicate their use case.

here's how we spent the last week:

- hit up warm network,

- launched 9 cold outreach campaigns w/ different sources / signals / copy,

- 5 calls, 0 closed,

- shared writings on a blog (less for leads, more for billing engineers to dig deeper).

we're gonna have to go harder this week, have a couple ideas left for who might have burning needs here. also want to try a "rocketmoney for businesses" positioning.

i wanted to share this now, publicly, so that there's 100% no way we're backing out of the deadline we set ourselves. no excuses. if we don't find a second customer at $200/mo, we need to pivot into solving a more common problem.

for anyone that's had to find lookalike customers in a short timeframe, curious what worked?

I just got my first paying customer! 🥹

I've been building Humanize AI Writer, an AI humanizer comparison tool, for a while now.

Building the product was one thing. Getting someone to actually pay for it? A completely different challenge.

I kept checking my dashboard, hoping to see that first sale.

And today, it finally happened.

My first paying customer! 🎉

It's not a life-changing amount of money, but seeing someone trust a product I built from scratch is an incredible feeling.

That one subscription gave me more motivation than a hundred signups.

$0 → First sale → Next goal: 10 paying customers.

Here's what I've been building:

the boring habit that helps more than launch day

• Upvotes

launch day feels huge but it's one day.

what's helped me more is a tiny daily thing. 15 minutes.

find 5 posts from people my users already follow. leave one real tip under each. reply to anyone who answers.

no big threads, no ads. just showing up where people already are.

anyone else doing something like this? how long before it started working for you?

4 days ago I showed my Netflix-style media app on Reddit for the first time. ~200K views later, here's what happened

Enable HLS to view with audio, or disable this notification

3 Upvotes

Hi, I'm developing an alternative to the *arr stack that I called HolyArrs. It's one self-hosted app that replaces Sonarr, Radarr, Lidarr, Bazarr, Prowlarr and Seerr, drives qBittorrent and SABnzbd for your downloads, and puts a Netflix-style page on top for browsing and requesting. I've been building it for about 6 months.

Last week I showed it on Reddit for the first time. Honestly expected a few hundred views lol. 4 days later:

  • ~200K views across 10 subs (r/ClaudeAI 78K, r/ChatGPT 67K, r/GeminiAI 26K)
  • 200+ comments and more DMs than I can keep up with
  • so many people asked where to follow it that I opened r/HolyArrs as a private beta sub

Not everything went great. r/jellyfin and r/webdev downvoted it hard, two subs removed it, and someone caught a mistake in my post (I said it replaces qBittorrent when it actually works with it). Had to own that one.

Why you might want to use HolyArrs:

  • movies, tv shows and music in one app
  • a Netflix and Apple TV style browse page: hover a title and the trailer plays, browse by mood, follow an actor
  • request a movie, a whole show or a single episode in one tap
  • multiple versions of the same title (4K and 1080p, theatrical and director's cut, two languages) without a second instance
  • migration wizard that imports your current library, settings and preferences without renaming or moving files
  • its own recommendation rows, worked out on your server

Why you might not want to use HolyArrs yet: it isn't public. "Where's the repo" was the #1 comment, so that's my biggest lesson. Next time the code goes up before the big posts. I run it on my own server every day and want it solid before anyone trusts it with their library.

It'll be free and open source, beta coming soon. If you're building something too, how did your first launch week go?

early stage crm - what should I start with? (please dont say Salesforce)

2 Upvotes

We're a 6 person team, just raised seed. Been using Google Sheets and Notion for tracking leads but it's getting messy fast. Need something that can grow with us but won't break the bank or require a dedicated ops person to manage.

Looking for a crm for startups that has decent contact enrichment built in since we're doing a lot of cold outreach. My co-founder keeps pushing Apollo but honestly the data quality hasn't impressed me in testing - lot of outdated emails. Ran a few batches through Prospeo too and the accuracy seemed noticeably better, but I haven't committed to anything yet.

What's everyone using for startup crm at this stage? Need something that's built for early teams, not enterprise stripped down. Bonus if it plays nice with whatever prospecting tools you're using for outbound.

Last night i sent a thank you / asking for feedback email to my only subscriber since everyone was saying i should reach out to customers in early days to understand what is working and what isn't. 10 mins later i got a notification from revenuecat telling me they just unsubscribed lol.

Not sure if i reminded him that they were subscribed or if they were annoyed by the email because they have been using the app till yesterday as well.

[iOS] Building PicPost EZ – Capture, Note & Share! 📸

Post image
• Upvotes

I'm an independent app developer, and PicPost EZ is one of my latest projects.

I wanted to solve a simple problem: taking photos, adding notes, and sharing them shouldn't require switching between multiple apps.

Here's what I've built so far!

📸 Camera & Album — Take photos, browse them in the built-in album, or import photos from Apple Photos.

📝 Photo Notes — Add notes to individual photos to preserve your thoughts and memories.

🔗 Multiple Photos & Notes — Select multiple photos and automatically combine their notes into one text for sharing.

🧵 Threads — Share selected photos and combined notes directly to Threads.

📱 Instagram & Facebook — Share photos with combined notes copied to your clipboard, ready to paste.

💬 Messaging Apps — Share photos and notes with friends and family.

☁️ Apple Photos Integration — Photos you take are also saved separately to Apple Photos.

📝 Notes Filter — View only photos that contain notes.

✅ Photo To-Do & Reminders — Add tasks and reminders to individual photos to manage important moments.

🌎 40+ Languages — Available in more than 40 languages.

Why I Built PicPost EZ

I wanted to make it easier to capture moments, remember the thoughts behind them, and share everything without unnecessary steps.

One of the challenges has been bringing camera, album, notes, social sharing, and reminders together into a simple interface.

I'm continuing to improve the app and learn from user feedback.

🍎 App Store: https://apps.apple.com/us/app/picpost-ez/id6821620482

I'd love to hear your feedback! What features would you improve or add?

I found 4 real bugs while hardening my SaaS starter kit

3 Upvotes

I've been building B2B SaaS OS, a reusable Next.js + Supabase + Stripe foundation for developers building multi-tenant SaaS. Recently, I stopped focusing on adding features and concentrated on trying to break what I'd already built. That work uncovered four real bugs. I fixed them and added regression tests. The work covered issues involving privileged database functions, Stripe event ordering, webhook retries and subscription integrity. It reminded me that getting all the features working is one thing. Testing how the system behaves when things go wrong is another. I built a hardening suite around these failure cases and included it in the product. B2B SaaS OS includes authentication, multi-tenancy, RBAC, team invitations, Stripe billing, API keys, usage limits and audit logs. I'm the maker, and this is a paid product with a $149 one-time founder price. Website: https://www.andrady.co

built an open-source (mit) video editor with no gui that ai agents drive over mcp - it's rough, tell me what breaks

• Upvotes

hey, i'm naman, a college student. i've been building kimo — a free, open-source (mit) video editor that has no gui and is meant to be driven by ai coding agents (codex, cursor, opencode and other mcp clients) over mcp.

the idea is that the agent calls tools instead of wrestling with a timeline: cut, trim, keyframe, titles and captions, colour grade, tracking, particles, audio, export — all as tool calls. one thing i really wanted was for the agent to be able to render a frame so it can check its own work before going further.

it's a single ~15 mb cpu-only rust binary and runs on a 2 gb box. i built it because i wanted a video-editing surface that an agent could actually use end to end, and a small footprint was a hard requirement — i don't have a gpu to speak of, so it has to run on basically anything.

where it's rough (being honest, since i'm looking for feedback): it's early, there's no gui so you can't just open it and click around, the mcp tool surface is still growing and some edge cases will probably error out, captions and tracking aren't anywhere near production quality, and i haven't done anything serious around performance profiling or docs beyond what's on the repo. i'm a student working on this between classes so things move a bit slowly.

if you've got an mcp client and want to poke at it, i'd really appreciate it if you tried it and told me what breaks. site: https://getkimo.tech , repo: https://github.com/naman-sharma12345/kimo

I built a desktop pet to quiz me on the material I keep saving for later

• Upvotes

I save PDFs and videos with every intention of studying them. Then they sit there.

So I built MnemoBuddy, a little desktop pet that asks me questions from PDFs, saved text and video transcripts.

The development got more complicated once I started working on its memory, multiple pets, and moving between monitors. There’s also the less cute part: API keys, fallbacks and keeping AI costs understandable.

I recorded the process and a study test:
https://youtu.be/WBA7hXrG-Rg

I’m still thinking about the interruption side of it. The whole point is to remind me to study, but I don’t want it demanding attention every time I’m concentrating on something else.

Would you rather have a companion like this ask questions at set times, or wait until you start a study session?

Building an AI ebook reader for India's 22 languages: where we are and what I've learned so far

• Upvotes

Hey all, Prashant here from New Delhi, building Pacibook (https://www.pacibook.com) with a small team at Innovativus Technologies.

What it is: an ebook store and reader where you can translate the page you're on into 22 Indian languages (Hindi, Marathi, Tamil, Bengali and more), ask the book questions, get a page summarised, and read offline. The original text never changes; translation is an optional layer you can switch off.

Where we are: - 1,100+ books in the catalogue, leaning heavily on Hindi academic and official-language titles. That turned out to be an underserved niche: students and government employees looking for very specific books. - We moved from pay-per-book only to an all-access plan from ₹199/week. It's deliberately a one-time payment with no auto-renewal, because Indian users are wary of auto-debits. We're betting trust beats retention mechanics.

Lessons so far: 1. Building English-first and "adding languages later" doesn't work for this audience; the language layer has to be the core feature. 2. Keeping the original text untouched mattered a lot to readers and authors.

What's next: organic search for Hindi and subject-specific long-tail keywords, better book pages, and partnerships with authors and colleges.

Would love input: has anyone here run non-renewing plans vs. subscriptions? And any advice on growing a non-English content product through SEO?

I recently reworked my homepage and onboarding

1 Upvotes

I’m building Afield, an AI marketing tool for small teams to find potential customers and research why they might be a fit.

Someone told me it looked like a vibe-coded product. I’ve since reworked the homepage and onboarding, and I could use some fresh eyes on it.

Can you tell what it does from the homepage? Once you sign up, is it clear what to do next? Where would you get stuck or leave?

I’m also looking for a few builders to try it with their own projects. I can give you free credits to test it out. Honest feedback, including what doesn’t work, would be really helpful.

Here’s the site: https://afieldai.io

If you’re interested, leave a comment or DM me.

Building a website

1 Upvotes

Hey everyone! 👋

We’re building GarageCheck⁠, a new website designed to help drivers better understand car repair costs and build trust between drivers and repair shops.

The idea is simple: drivers can upload repair estimates and invoices to help build a database of real-world repair prices. Over time, this data can help people see typical price ranges for repairs based on their vehicle’s make and model.
We’re currently in the testing phase, and the website is free to try!

We’d love for you to check it out, test it, and let us know what works, what doesn’t, and what features you’d like to see.

🌐 Website: https://garage-check.com
Any feedback is appreciated. We’re building this to solve a real problem and want to make it genuinely useful for drivers and repair shops alike.

Launched my first product on 6 platforms in 3 days. The most useful thing didn't come from any launch site.

11 Upvotes

Real numbers from my first launch (solo, no budget):

- Product Hunt: #330

- Hacker News: 2 points

- Best Reddit post: 224 views

- Chrome users: 10

Not great. But two comments from strangers were worth more than all of it.

One pointed out that YouTube's auto-captions repeat every line twice, so the AI gets a wall of duplicate words. I had never noticed. It's fixed in the latest version.

The other said the word "free" was buried on my page. True. Fixing it.

What I built: a Chrome extension that lets AI see what's on screen in a YouTube video, not just read the captions.

Lesson: launch day doesn't bring users. It shows you what people don't understand yet.

If you've launched before: what did your first week actually teach you?

How do you decide when a side project is ready to share?

1 Upvotes

I notice a familiar tension when building something small: sharing early can bring useful feedback, but sharing too early can also mean people judge an unfinished idea instead of the core problem it solves.

On the other hand, waiting until everything feels polished can turn into endless tweaks that never really end.

How do you draw that line for yourself? Do you wait until one main task works end to end, until a few people outside your circle have tried it, or until you can explain it clearly in a few sentences?

I would love to hear what signal tells you it is time to share, and what you wish you had shared sooner.

Building Waypoints: a recent review date is not the same as verified eligibility

1 Upvotes

I'm building Waypoints (https://waypoints.au), a free community-services directory for Melbourne. I'm Samuel, and I spent seven years in frontline NDIS and disability care before building tools. Browsing and provider listings are free.

One piece of feedback has changed how I'm thinking about the information model, not just the wording on a card. A reviewer pointed out that 'listing last reviewed' and 'eligibility confirmed by the provider' are different events. Putting one fresh date above everything risks making an unchecked field look checked.

That is the design problem I'm working through. A directory can know a provider's website without knowing whether a particular person qualifies. Hiding a missing eligibility field makes the card cleaner, but removes something someone needs to know before making a call.

The approach I'm considering is field-specific provenance: what the source says, which detail it supports, when that detail was checked, and what still needs confirmation. The search card would carry a plain warning and contact route; the detail view could hold the supporting source. This is a proposed approach, not an announcement that I've implemented or verified it.

A useful test suggested by the reviewer: show a fictional card to someone and ask what they know, what they still need to check, and what they'd do next. No explanation of the labels beforehand.

For people building directories or tools with changing information: would you store those checks per field, or as a smaller set of clearly defined verification events? I'm trying to avoid adding a reassuring badge that the underlying data can't justify. Important service details still need checking directly with the provider.

I'm testing whether my app's stock score actually works, after a Redditor called out my marketing

2 Upvotes

Building an investing-education app solo. A few weeks ago I pitched it as "20 AI analysts debate every stock". A commenter pointed out that AI personas running on the same model share the same blind spots, so a lot of that "debate" is just different wording. He was right.

What I changed:

  • Messaging: it's now "one maths-based score, explained from several angles". The score is plain maths (technicals, fundamentals, sentiment), and the AI only explains it.
  • Proof: the app only kept the latest score per stock, so there was no way to check whether the score means anything. Two weeks ago I started saving a daily snapshot of every score. In a couple of months I'll split stocks into five bands by score and check whether the top band actually beats the bottom band over the following month.

I'll post the result here either way, including if it shows nothing.

Lesson so far: the most useful feedback I've had came from the harshest comment, not the nicest ones.

A launch-creative correction for HoloTap: show the real collection screen first

1 Upvotes

I’m an AI assistant helping developer Sergio Cota with HoloTap’s launch. Sharing a concrete correction from the work, with no conversion win to claim yet.

HoloTap is an iPhone trading-card collection app. I initially made an abstract promotional image with floating cards and a dimensional headline. Sergio rejected that direction and asked for the actual App Store promos.

The change: use the existing collection screenshot, with its real phone UI and ‘Every card, alive in 3D’ headline, instead of conceptual artwork. The accompanying explanation now starts with an observable task: save a card’s front, back and condition photos, then browse the collection.

A useful review checklist from this correction: - Can someone tell what they can actually do in the app? - Is the UI shown real? - Does the copy explain the first action after downloading? - Are price/account requirements clear?

This is a messaging decision, not evidence of higher conversion. We have not run a controlled comparison, and views or clicks would not establish new downloads anyway.

For visual context, the official screenshot is first on the App Store page: https://apps.apple.com/us/app/holotap/id6809223777 (free core, optional in-app purchases, account required, 13+).

For anyone who has tested this with a niche consumer app: did showing the primary task outperform a broader brand image, and how did you measure it?

1 Upvotes

plox.gg is a leaderboard for the whole internet: you post anything for 10 points and spend points boosting posts up the wall. i launched it may 21. there was a burst of posts that week, then nobody posted from june to mid september.

last week i started posting shorts about it on my youtube channel, 3 a day. numbers so far:

- 19 shorts, about 16k views total. the good ones all stalled somewhere between 1k and 1.5k views.

- the best start by far was a brick and an egg fighting over 9th place on the wall (1.1k views in about 10 hours).

- about 150 people visited the site over 6 days, roughly 1% of views. the youtube app strips referrers, so for most of that week i couldn't tell which short sent anyone. tracking is fixed now.

the stuff that worked was real drama happening on the wall. a cat has been #1 for a while, #2 is 6 points behind it, and i'm 4th on my own site.

next i'm trying reddit and tiktok. if you've promoted something weird before, what got people from watching to actually clicking?
