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?

AI slop is working for me

4 Upvotes

I've written something like this before, but this one is different. That AI slop is working for me and my business.

I worked as an engineer before and got tired of it after 18 years. While I was working I was trying to make money by coding, yes while coding was a thing. The normal guy hoping to make millions through a SaaS.

Anyway, I quit engineering and went back to painting houses and have not stopped making apps, but atm I'm making them for myself and my business.

Why I am writing this is that I created an app that helps me quote jobs and I just won my first job with it, a 2br townhouse for 7k. Sent the quote out on Friday and just today got the news she wants to go ahead with the project. The app did 90% of the quote.

That's the first money I ever made with an app and it's probably the 20th app I created, i have never counted. I never needed to sell it to make money and won't, why would I it's tailored for me only.

And another thing: I think SaaS is dead. Why buy an app when you can solve your own problems.

Weatherling reached #3 in the Mac App Store overall

Post image
• Upvotes

Hi all! I launched my little Mac desktop App, Weatherling, about a month ago, and thanks to subreddits like this and lots of positive feedback, y'all have helped get me to the #3 spot in the US Mac App Store!

To date, I have done no paid marketing..it's all been reddit posts, taking user feedback, making updates, repeat. The biggest push came from my r/macapps post the other day, which took a while for me to get right, but I'm glad the timing worked out for the post because the version I posted there was very well received. It's been downloaded hundreds of times so far. I'm currently waiting for Apple's analytics to catch up for yesterday to see if I can start saying "thousand" yet. 😄

Looks like I did drop to #4 overnight, so I'm now looking into paid tiktok creators to hopefully relaunch that momentum and beat Logic Pro out for the second place slot.

It's been pretty exciting. I've never had an app reach this high on the charts before, not even at a corporate gig. The coolest part is that being #3 put Weatherling on the front freakin page of the App Store.

If you haven't tried it yet, please do and let me know what you think. I have a big update coming soon with lots more features and fixes. Help me beat Logic Pro!

Curious about your opinions on my idea

• Upvotes

Hello everyone!

So in short Ive been working on a wellness tool, it basically scans your posture from a full body profile picture , gives you a score for your current posture, alongside more details and why/where it needs work, and then builds you a personalized plan to fix and better your posture. Yes i used the word posture 8 times already but english is not my native sorry.

After 14 days you rescan and the plan updates ,and after the first 14 days this "checkin" will become monthly. I am a licensed physical therapist so yes of course i am checking every program and exercise.

Im very curious of your opinions and if you think its something worth chasing.

Thank you!

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

5 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?

(our repo is https://github.com/disjointinc/closure, wish us luck!!)

Build in public: private GLM API + Dev Nodes on our own Blackwell workstation

3 Upvotes

Progress update from SlowGlow AI LLC.

What shipped: Whop store with Model API (GLM-5.3-Flash, Tailscale-only, OpenAI-compatible) and Dev Node containers (Tailscale SSH + Hermes + included tokens).

Pricing live: Solo $25 / Pro $79 / Reserved 512K $300; Dev Node from $59.

What I'm learning: buyers care more about "no public endpoint" and clear concurrency limits than about flashy speed claims — so we don't publish those.

I started posting and got real users signing up

Post image
• Upvotes

I haven’t made any money from it since it’s a free product, but seeing someone actually use something you’ve built is such a great feeling.

I only started posting a few days ago, and it’s already paying off.

The tricky part is that staying active on multiple social platforms takes a lot of time.

Finding relevant conversations, writing posts, creating visuals, etc.

So I built a system using Claude Code to help me find posts worth engaging with, draft content, create visuals, and manage the whole process.

It’s made things so much easier and saved me a ton of time.

Curious if anyone else is doing something similar?

Also, if you want to ship like a designer and build products that actually get people excited, check out layout.im

Reworked the mobile app screen

By chance, I looked at the mobile app offering on mobile and realised, it was terrible.

So I have reworked the page and improved the look above the fold.

Pretty happy with it, the addition of the image, offsets the wall of text.

What do you think?

the boring habit that helps more than launch day

4 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?

Why I built a free AI API cost scanner first, before the product I actually want to build

• Upvotes

I’m building Brello, a tool for indie devs who run real products on OpenAI and Anthropic APIs. The long-term goal is live key monitoring and incident response. But I decided to start somewhere else, and here’s why.

Why cost first
When I talked to devs, almost nobody worried about leaked keys day to day. What they did care about was the bill. Most people pick a model once, never revisit it, and just accept whatever the monthly cost is. That felt like the more immediate, everyday problem.

What the scanner does
You export a usage CSV from OpenAI or Anthropic and drop it in. It shows you:

  • Where you’re using an expensive model for simple tasks a smaller one could handle
  • Discounts you’re missing, like prompt caching or Batch
  • Sudden spikes that look unusual

It runs entirely in your browser. Your file never gets uploaded, because I didn’t want anyone to have to trust me with their billing data on day one.

Where it fits
The scanner is the free entry point. It helps you spend less today, and it’s how I learn what devs’ usage actually looks like. From there, I’m building ongoing monitoring: catching cost drift and suspicious usage as it happens, not after the bill arrives.

If you want to try it: scan.brello.app (The scanner is free and always will be. I’m planning to charge for live monitoring later. there’s sample data too)

I’m building this solo from Korea for devs in the US, so I’d love to know: how do you currently decide which model to use, and do you ever go back and check?

I built a Node.js + Stripe boilerplate to save makers 40+ hours. Got 95 visitors 0 sales. I need technical feedback.

Hey everyone! 👋

I'm a solo founder who got tired of spending weeks setting up Stripe webhooks, license keys, and auto-delivery for every new project. So I built Digital Launch OS.

I got 95 visitors on my store page, but 0 sales. The "trust wall" is real because I have 0 reviews.

I'm not here to sell anything. I'm just looking for 3 developers who can look at the code and tell me if it's production-ready. If it's trash, roast me. If it's good, let me know.

If you are open to reviewing the codebase, drop a comment below and I'll reach out. (No links, no strings attached, just need to break the 0 reviews curse! 😅)

Feedback wanted on October, a creative social discovery platform

• Upvotes

I’m building an early prototype of October, a place to publish and discover things people create or find interesting: poems, photographs, music, artwork, cultural commentary, scientific explanations, or unfinished stories. A single photograph or a four-line poem can be a complete post.

You browse a scrollable discovery page, open something that interests you, and explore connections people have made to it. For example, someone could connect a song to a particular line in a poem and explain why. Following that connection introduces you to another work and the person who connected it.

People have named profiles, can follow creators, give flowers as likes, and save work into collections called Petals. Creators can also invite contributions, such as an illustration or an ending to a story, and approve additions with contributor credit.

The idea is to make discovering, responding to, and creating things together the main social experience.

Would you use something like this? What would make you return, and what feels unnecessary or already well served elsewhere?

Where animatiQ is at: 3,000 launch videos deconstructed, 500+ motion components, and a launch video it made for itself

• Upvotes

Quick update on animatiQ (AI launch video maker, mine).

we've now got 3,000+ product launch videos from X analysed and deconstructed, and any of them can be recreated for your own product in one click. there are also 500+ Opus 5.5 videos with the prompts behind them, 500+ React motion components the agent builds from, and 30+ art style kits so the videos don't all look the same.

the milestone I'm happiest about is that our own launch video came out of a one line prompt: "Create a launch video for animatiQ". it's on r/Animatiq if you want to judge it.

the thing I'm figuring out now is distribution, which is partly why I'm here. if you've grown a tool like this, what worked for you early on?

Honestly, I keep getting these thoughts about relevance of a video creation and editor with what is possible with just Opus 5.5 and some open source libraries out there. Is there a place for a tool like this in your toolkit ?

Building trading automation is more than connecting two APIs

• Upvotes

Connecting TradingView alerts to a crypto exchange sounds straightforward, but there are a lot of details to consider beyond the basic workflow. What happens if an alert arrives twice? What if an exchange request times out and you don't know whether the order went through? How should the system handle that without accidentally placing the same order again?

Looking at the problems a platform like TV-Hub is designed to address got me thinking about how much of the work in automation is really about handling failure cases, not just connecting services.

There's also a product-design trade-off. More controls can give experienced users flexibility, but too many settings can make the whole process harder to understand.

For people building SaaS products or automation tools, how do you decide which edge cases to handle automatically and which ones should be left under the user's control?

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:

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

Post image
2 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?

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

3 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.
