Both are open source harness options with comparable terms, so the choice comes down to which model of the problem you prefer — compare the descriptions below rather than the licence.
Open-source meta-harness that orchestrates Claude Code, Codex, Cursor, OpenCode, Hermes and Pi from one session, on any device.
A common orchestration layer over other harnesses rather than a harness of its own — swap Claude Code/Codex/Cursor/etc. in and out, enforce policies, and run sessions in cloud sandboxes (Modal, Daytona, E2B and others).
Everything is a plugin — the model adapter, the tool registry, the sandbox and the agent loop itself are all swappable.
Web UI first — `dsh web` serves on 127.0.0.1:3080 rather than taking over the terminal. Built on Cordis. Still a developer preview: DeepSeek warns of compatibility-breaking changes, so pin the version.
