Every option in the catalog for when you need to hand a multi-step task to an AI and walk away — 24 autonomous AI agents, 22 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 24 of them, ordered free tiers first: AutoGPT, Kortix (Suna), Agent Zero, AgenticSeek and CowAgent. 22 of the 24 are free or have a free tier. Each entry states what it uniquely does rather than a score.
12 on this page are marked fully free with no paid plan at all: AutoGPT, Kortix (Suna), Agent Zero, AgenticSeek and CowAgent. The remaining 12 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.
AutoGPT, Kortix (Suna), Flowith, Genspark and HyperWrite AI Agent all work in a browser tab with no install needed — just open the site and go. 9 of the 22 free autonomous AI agents listed here are browser-based.
Flowith, Genspark, HyperWrite AI Agent, Manus and MiniMax Agent support Google sign-in, so you can start without creating a new account. That's 8 of the 22 free autonomous AI agents on this page.
