Niceee. If you want to share it with other builders, get your first users, collect feedback, and test it out, we’ve just launched a platform for exactly that. We literally just went live.

PnLytix is the trade journal for live brokerage books and prop desks — honest P&L, firm rules when you need them, and AI that shows the sessions that actually pay.

Built with Codex from @OpenAI: a cemetery for abandoned side projects. Founders write an obituary, preserve the lesson and link to what they're building next. A failed idea might help the next one grow. What would you bury, @sama? #buildinpublic

Free calculators for DIY home projects like woodworking, decks, concrete, and drywall.
u/CaboWabo55 · Reddit
Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.

Free roast, no signup. Reply with your landing page URL. I'll run it through -- 50 AI-simulated customers from YOUR target audience -- and post the verdict here: → score /100 → top objections → the single most brutal verbatim quote First 10 replies.
