Every option in the catalog for when you need to describe an app in English and get a running one — 18 AI app builders and vibe-coding platforms, 17 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 18 of them, ordered free tiers first: Cloudflare VibeSDK, bolt.diy, a0.dev, Amazon PartyRock and Base44. 17 of the 18 are free or have a free tier. Each entry states what it uniquely does rather than a score.
2 on this page are marked fully free with no paid plan at all: Cloudflare VibeSDK and bolt.diy. The remaining 16 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
