All 126 ai agents & automation tools in the catalog across 7 sub-categories, ordered free tiers first.
Flocci AI Tools lists 126 of them, ordered free tiers first: AutoGPT, Bolna, Flowise, Google Opal and Kortix (Suna). 123 of the 126 are free or have a free tier. Each entry states what it uniquely does rather than a score.
76 on this page are marked fully free with no paid plan at all: AutoGPT, Bolna, Flowise, Google Opal and Kortix (Suna). The remaining 50 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, Bolna, Flowise, Google Opal and Kortix (Suna) all work in a browser tab with no install needed — just open the site and go. 52 of the 123 free AI Agents & Automation Tools listed here are browser-based.
Google Opal, Sim, Cloudflare Agents SDK, mcp-use and Botpress support Google sign-in, so you can start without creating a new account. That's 40 of the 123 free AI Agents & Automation Tools on this page.
