mxr is a command-line tmux workspace manager. Remote machines forget your setup; mxr doesn't. Register named sessions with their working directories, then sync the config and the binary across every machine, so your development environment is one command away, anywhere.
Beyond sessions it wraps the day-to-day: integrated git workflows (commit, push, and open a PR in one command), project scaffolding from templates (Rust, Python, Go, TypeScript, and more), branch automation, deploy targets (Cloudflare Pages/Workers, Fly.io), and Claude Code integration for seeding repos with AI skills. Ships as a dependency-free static musl binary for Linux.
