A few months ago I realized the hardest part of building solo wasn't lack of ideas.

It was knowing which ideas were real.

Every "AI startup idea generator" I tried gave me plausible-sounding ideas with fake source links. Made-up "users" who don't exist. Fabricated Reddit threads. Vendor blog posts being cited as proof of demand.

I wasn't validating anything. I was just generating slop.

So I built something different.

Pain Radar pulls real founder problems from Hacker News, GitHub Issues, Stack Exchange, and Lobsters. Every idea links back to the actual person describing the problem in their own words. The AI doesn't generate ideas — it clusters real human posts retrieved from official platform APIs. Every source is clickable and verifiable.

Last week it surfaced a card about helping computing instructors integrate AI into their curricula. The source was a real Hacker News post from a University of Illinois CS professor describing exactly that pain, in his own words, written a week earlier.

That's the point. No fabricated evidence. No AI hallucination. Just real people whose problems you could literally cold-email tomorrow.

What's the hardest part of validation for you right now — finding real users to talk to, or knowing if the idea is even worth pursuing?

Four weeks ago, I released Line Cal - an app that let's users put their calendars on a timeline, with notes and an integrated Kanban task board. I've gotten 40 sign-ups since I launched, am supporting 21 languages, and am continuing to iterate on a consistent basis.

I wanted to share a short demo video of adding an item from the backlog directly onto the timeline to showcase some of what this app can do. Users can use it with or without signing (it uses a local-first architecture, with cloud sync for authenticated users).

I built TestLaunch because I keep seeing Play Store developers posting that they need testers, feedback, or people to join their testing links.

TestLaunch is a free place to list your app, share your testing link, and let testers find projects that need help.

You can add your app name, platform, category, test duration, contact email, description, testing link, and what kind of feedback you are looking for.

The goal is simple: give Play Store developers one clean page to share instead of chasing scattered tester posts everywhere.

It is brand new, so feedback is welcome.

I’ve been building TIPITY ONLINE, a print-on-demand merch platform designed to remove the usual setup wall.

Instead of building a full Shopify store, connecting apps, setting up product pages, fighting mockups, and trying to make everything shareable, the flow is basically:

upload or create an image → choose a product → generate the merch preview → create a listing/share link → share it anywhere.

The buyer lands on the product, picks options like size/color, checks out, and the order routes through the fulfillment flow. It supports regular merch purchases and creator-style merch links where someone can make something and sell it without needing to build a whole storefront first.

I built this because I think a lot of people have ideas, art, jokes, slogans, photos, designs, or small audiences, but they never turn them into products because the setup feels too heavy.

Live app:

I’m looking for honest feedback from people who sell merch, use POD, run small online businesses, or have tried Shopify/Etsy/Printful-type workflows. Does this kind of “make it and share the link” flow solve a real pain point for you, or would you still rather build a full store?

I am an indie developer. I built an Android app. Code worked. Design worked. Then Google told me I needed 12 testers for 14 days before I could publish. I did not have that.

I tried friends. They forgot after day 2. I tried test for test groups. People disappeared. I failed three times. Wasted over a month.

So I built RealAppTesters.

You add our testers emails to your Google Play Console. We provide 12 testers who use your app every day for 14 days. We track daily activity. If someone drops off, we replace them. After 14 days, you apply for production access.

No app to download. No system to learn. No testing other people's apps.

I have helped over 50 indie developers pass closed testing so far. All customers came from Reddit. No ads. No paid promotion.

If you are building an Android app and stuck on closed testing, this is for you.

Hi, I have just l launched my first app but struggling to get any volume of downloads, how are people managing their projects any tips will be greatly appreciated. https://apps.apple.com/gb/app/trekt-travel-tracker-budget/id6762569699 check it out. Thanks in advance.

It is a productivity app for people whose plans keep changing.

The problem is not always laziness or lack of discipline.

Often, people start with a clear plan, but then priorities shift, new work appears, and the system they created last week no longer fits this week.

It helps people turn messy ideas into a clear plan, work in short focus periods, and reflect when things change.

The loop is simple:

Plan → Focus → Reflect → Improve

It is still early and looking for people who genuinely feel this problem.

How would you find early users for something like this? www.ritualy.ai

Reddit, LinkedIn, founder groups, direct outreach, or free project organisation sessions?

Hey everyone

I’ve been building Questa AI and just opened it up for early users — would really value honest feedback.

The problem that pushed me to build this:
people are already pasting sensitive data (client info, internal docs, etc.) into AI tools every day just to get work done faster.

It’s not a “future risk” — it’s already happening quietly inside most teams.

So I built Questa AI as a privacy layer for AI:

• detects & anonymizes sensitive data before it reaches an LLM
• lets you actually use AI with real data (without exposing it)
• adds a layer of control over this whole “shadow AI” issue

It’s still early, and I’m actively shaping it based on feedback from people using it right now.

I’ve made it free to try during this phase, mainly to get real usage and learn what’s actually useful.

If you’re experimenting with AI in real workflows, this might be worth trying now rather than later:

Would genuinely appreciate any feedback — even if it’s just “this doesn’t solve my problem”

Got this traffic for my astrology website in 18 days is it ok

Hey guys, I'm an engineer/lurker here who has built a new product called Stoney! I am the solo founder/engineer on this project.

I built this because requirement drift is one of those problems every dev team has but nobody has good tooling for. A requirement gets written, gets built, and then six months later something changes quietly and nobody connects it back to the original ticket. The failure mode I kept seeing: a requirement like "free tier users get 100 requests/day" starts as a Jira ticket, gets built out, and slowly drifts until different parts of your codebase enforce it differently. No alert fires. No test fails. A customer just gets a weird experience and nobody knows why.

Stoney connects the dots from ticket to code to live API. It builds a registry of the business rules your system actually enforces, watches your repos for drift, and when something breaks it shows you the PR that caused it, the ticket that authorized it, and who owns the rule.

Connect your GitHub, Jira, and Slack in a few clicks and you're running in under 10 minutes. No config files, no manifests.

Free tier is permanent, no card required. Would love honest feedback from anyone. Am I hitting the mark here or is there a gap in what you would expect to see? You can find my product at stoneydev.com

been using this for the last week. drop a file in the browser, share the link, the recipient downloads it directly from your machine. nothing uploads anywhere.

the part i actually like is it doesnt care what device anyone is on. iphone to windows works. android to mac works. no app to install on either side, just a browser tab.

encrypted, no size cap, no account needed.
