codemax

codemax is a terminal-based development tool that combines multiple AI coding subscriptions into one interface.

Codemax is a terminal interface that brings together multiple AI coding subscriptions, including Claude Code, Codex, OpenCode, Grok, Cursor, and Antigravity. When one agent reaches its usage limit, the tool automatically transfers the task, project history, and context to the next available agent without requiring a restart. It is designed for developers who pay for multiple AI plans and want to prevent mid-task interruptions. Features include daily budget limits, one-step code undo, file attachment support, and second opinions from alternative agents. The software runs locally using existing user logins and requires no pay-per-token API keys.
