All 69 code & development tools in the catalog across 12 sub-categories, ordered free tiers first.
Flocci AI Tools lists 69 of them, ordered free tiers first: Aider, Cline, Crush, DeepWiki and Gemini CLI. 62 of the 69 are free or have a free tier. Each entry states what it uniquely does rather than a score.
11 on this page are marked fully free with no paid plan at all: Aider, Cline, Crush, DeepWiki and Gemini CLI. The remaining 58 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.
