Weights you can download, runtimes you can install and frameworks you can read — for privacy, cost control, or just not wanting a dependency on someone's API.
Flocci AI Tools lists 69 of them, ordered free tiers first: Agno, Aider, AnythingLLM, AWS Strands Agents and Cline. 67 of the 69 are free or have a free tier. Each entry states what it uniquely does rather than a score.
50 on this page are marked fully free with no paid plan at all: Agno, Aider, AnythingLLM, AWS Strands Agents and Cline. The remaining 19 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.
