Built Cairn alone for months. No co-founder, no funding, no safety net. Just me and the problem.
First launch ever. First upvote just came in 44 minutes ago from @david_firouzbakht Thanks david! If you're a solo founder who knows what this feeling is I'd love your support today. Upvote Cairn here: Cairn
More and more people ask ChatGPT, Claude, Perplexity or Grok for product recommendations instead of Googling. While building my own projects I noticed many sites never appear in those answers, often for boring technical reasons: AI crawlers are blocked, pages aren't indexed in the search engines these assistants rely on, or there's simply no page that clearly answers the buyer's question.
So I'm building AURA GEO (aurageo.io). You connect a site once, and an agent checks how AI assistants see it, fixes the technical side (robots, sitemap, llms.txt, indexing in Google, Bing and Brave), works through a verified step-by-step plan, and shows how many visitors actually come from each AI assistant. It also works over MCP, so you can drive it from Claude or Cursor.
Every reading app we tried for our two baby girls wanted more of our attention, but excessive screen time is bad for kids. It also felt backwards for something that s supposed to be about paper books and each other.
I've been managing Shopify stores for years, and one thing that always frustrated me was how easy it is to track revenue, but how difficult it is to know what you're actually making.
Between product costs, shipping, payment fees and advertising, spreadsheets quickly become a mess. And many existing profit tracking tools are quite expensive for smaller merchants.
So I built ProfitSimple. It's a simple Shopify profit dashboard that brings your revenue and costs together, so you can see what's actually left.
Epictetus opened his Handbook with one distinction: some things are up to us, most are not. I kept forgetting it in the heat of the moment, so I built a place to practise it.
Yours, Not Yours is a free Stoic practice ground. You sort situations from everyday life (a rejected offer, a gossiping colleague, news you can't stop scrolling) into two boxes: yours or not yours. It goes from quick true or false propositions to "cuts", where you take one situation apart piece by piece, plus true stories from history. Every answer comes with an explanation and a quote. Free, no account needed.
I'm Sri, a solo developer from India, and I recently launched xReach. I've spent the past few months building it, fixing bugs, figuring out payments, and trying to get everything ready. Honestly, getting the product live took a lot more than just writing code.
The best moment so far? Getting my first payment just 6 hours after launch.
