Claude Code opens public beta of self-hosted environments; v2.1.224 adds cross-session agent messaging
Anthropic
Anthropic launched a public beta letting Claude Team and Enterprise customers run Claude Code cloud sessions on their own infrastructure via `claude self-hosted-runner`, keeping repository checkouts, build artifacts, and secrets inside the organization's network. The same v2.1.224 release also added cross-session `SendMessage`/`ListAgents` APIs so sessions on different machines can message each other; v2.1.225/226 followed on August 8 with gateway spend-limit warnings and MCP OAuth fixes.
Why it matters
Self-hosted runners address a common enterprise blocker (data residency, internal-only services), while cross-session messaging expands multi-agent orchestration — two significant capability jumps in one release cycle.
Importance: 3/5
Two significant capability additions (self-hosted compute, cross-session messaging) in one release, both official-source confirmed.
