Excalibur (xcb)
Route coding tasks across your Claude, Codex, and Devin subscriptions
Visit xcb.sh ↗What is Excalibur (xcb)?
Excalibur is a terminal agent that manages multiple AI coding subscriptions, automatically selecting the best account and model for each task based on quota availability and reset timing. It works as a standalone coding agent or integrates into existing workflows via a TypeScript SDK, returning results as JSON.
The tool helps developers maximize their subscription value by prioritizing unused quota before resets and continuing work across accounts when limits are reached. It also supports importing and resuming recent Claude and Codex conversations. Built with Claude Code, xcb runs on macOS, Linux, and Windows via WSL2, and is free and open source.
