Every option in the catalog for when you need to wire apps together and let AI do the middle step — 17 AI workflow automation tools, 16 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 17 of them, ordered free tiers first: Langflow, Windmill, Activepieces, Botpress and Chatbase. 16 of the 17 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: Langflow and Windmill. The remaining 15 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.
