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.
Self-hosted gateway putting an agent in Slack, Telegram, WhatsApp, Signal, Discord and iMessage at once.
One Gateway process fans out to every channel plugin. Needs Node 22.22.3+ (26 recommended); the installer provisions it.
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.
