Every option in the catalog for when you need to wire apps together and let AI do the middle step — 24 AI workflow automation tools, 23 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 24 of them, ordered free tiers first: Flowise, Google Opal, LangBot, Langflow and Sim. 23 of the 24 are free or have a free tier. Each entry states what it uniquely does rather than a score.
8 on this page are marked fully free with no paid plan at all: Flowise, Google Opal, LangBot, Langflow and Sim. 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.
Flowise, Google Opal, LangBot, Langflow and Sim all work in a browser tab with no install needed — just open the site and go. 19 of the 23 free AI workflow automation tools listed here are browser-based.
Google Opal, Sim, Botpress, Chatbase and Dify support Google sign-in, so you can start without creating a new account. That's 13 of the 23 free AI workflow automation tools on this page.
BISHENG and Coze Studio can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 2 of the 23 free AI workflow automation tools here run offline.
