Sourced hands vibe coders real problems people already complain about — with proof someone will pay for the fix, matching free APIs to build it with, and a brief ready for whichever tool you build with.
"Build a todo app for dog walkers" isn't a business — it's a hallucination with a UI. Every card in Sourced starts as a real complaint pulled from a forum, a review, or a job post, from someone already paying for a worse fix or no fix at all.
Every idea earns its place before it reaches your feed.
Reddit threads, 1-star G2 reviews of paid tools, and recurring Upwork gigs — places people already describe what they'd pay to fix.
Ranked on repetition, an existing (mediocre) paid competitor, and whether a solo builder can actually ship it in weeks, not months.
Buyer profile, proof-of-demand quote, MVP scope, matched APIs, and a step brief — formatted for the tool you picked above.
Stage 3 of the pipeline matches each build brief against a structured copy of the public-apis directory — 470k+ stars, MIT-licensed, maintained by the open-source community — so you're never staring at a brief wondering what actually powers it.
Full match list, auth type, and free-tier limits ship with every Builder+ brief. Browse the source directory ↗
41 separate complaints across r/Bookkeeping and r/Accounting in the last 90 days, plus a cluster of one- and two-star G2 reviews on two mid-tier bookkeeping tools naming this exact gap. Several already pay a VA specifically to reformat exports by hand.
Cancel anytime. Every paid plan comes with a 7-day refund, no questions.
From a structured, regularly-synced copy of the public-apis directory — a 470k-star, MIT-licensed community list. We match categories to your idea's build brief; full docs links and rate limits ship on Builder and above.
Any AI-assisted builder — Claude Code, Cursor, Windsurf, v0, Bolt, and more. Pick yours in the hero above and every build brief formats for it automatically.
No — every card starts from a real, sourced complaint, not a generated headline. You can see the source signal behind each idea, not just the pitch.
Some won't — that's true of every idea anywhere. Sourced removes the guessing on whether anyone wants it in the first place; the execution risk is still yours, same as any build.
Go find it — or let Sourced bring it to you every Monday.
