The free OpenAI Codex alternative
OpenAI Codex brings autonomous coding to the terminal and cloud, billed by usage. FreeCoder offers the same autonomy — planning, multi-file edits, command execution — with a free, uncapped built-in model, or your own key if you'd rather route to a specific provider.
