Terminal & CLI Agents — straight answers
What are the best free terminal and CLI coding agents?
Flocci AI Tools lists 13 terminal and CLI coding agents, ordered free tiers first: Aider, Cline, Crush, Gemini CLI and Goose. 12 of the 13 are free or have a free tier. Every entry states what it uniquely does, not a score.
Are there completely free terminal and CLI coding agents?
Yes — 7 of these are marked fully free with no paid plan attached: Aider, Cline, Crush, Gemini CLI and Goose. The rest are freemium, trial or paid, and each row states which.
What should I look for in terminal and CLI coding agents?
Start with what you need to do: let an agent run commands and edit files from your shell. Then check the pricing tier, because "free" here means no paid plan at all while "freemium" means a free tier under paid plans. Every tool on this page lists both.
