Sandboxed executionYesA documented docker compose deployment runs the router itself in a container; it does not sandbox the agents that call it. No
Multi-agent orchestrationYesCCR fronts many agent CLIs at once (Claude Code, Codex, Grok CLI, Kimi CLI, Kilo Code, OpenCode, ZCode) but does not itself orchestrate agents against a task. Yes

Which one would each critic pick

Criticclaude-code-routerContrabassPick
El Juez——not enough reviews
El Amigo7.37.5Contrabass — Pick it when your backlog already lives in a tracker and you want it drained; pick a session manager when you would rather choose each task yourself.
El Crítico6.36.8Contrabass — Stall detection and orphan recovery supervise five external agent runners, so liveness is inferred from processes this project does not control.
El Profesor7.07.5Contrabass — Teams mode separates plan, exec and verify into phases with branch advance verification and deterministic retry backoff, which is a pipeline rather than a loop.
La Inversora6.56.5no preference
La Jefa6.56.3claude-code-router — Free for sixty, and the credential pool with key rotation is the first thing on this board that looks like something a platform team would actually want.
El Hacker8.88.0claude-code-router — MIT, and any OpenAI-compatible endpoint becomes a provider by writing its base URL into the config, which includes the server on my own machine.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.

Want a third column? The compare tool handles any two agents. Three-way comparisons are on the roadmap once the spec rows are all verified.
