Warp alternative: run your own Claude Code and Codex, without a platform
Warp has grown from a modern terminal into an agent platform: its own coding agent, cloud agents triggered from issues and Slack, factories defined as code, and pricing per agent run. If you want that whole stack, Warp is the product for it.
omux is the opposite shape. It doesn't bring an agent, a cloud or a login. It's a native macOS window that runs the Claude Code and Codex sessions you already have, many at a time, and makes them easy to watch and answer. This page is for people deciding between those two shapes.
