Codeband: letting Claude Code and Codex collaborate on the same coding task

Reddit r/AI_Agents Tools

Summary

Codeband is an open-source tool that enables Claude Code and Codex to collaborate on coding tasks by facilitating context handoff between agents via the BAND protocol.

I’ve been experimenting with a workflow where one coding agent implements and another reviews. For example, Claude Code writes the code, then Codex critiques it, or vice versa. It feels a bit like **ensemble learning** for coding agents. The value isn’t just “more agents”, but different models with different strengths and blind spots reviewing each other’s work. That’s why we built Codeband: an open-source demo that connects Claude Code and Codex through BAND so they can hand off context without manual copy-paste between terminals. I wrote more about the idea in a blog post - see below in the comments. Curious if others are trying similar cross-model coding workflows.
