Show HN: Share your Claude Code sessions with others (github.com)

AgentBeam is an open-source tool that lets Claude Code developers share complete working sessions peer-to-peer: conversation context, memory files and the exact codebase state are packaged and sent directly between machines with no servers, accounts or uploads. The basic flow is simple — run agentbeam beam-session to create a ticket and wait for a recipient, who runs agentbeam receive <ticket> (optionally --target) and can immediately pick up work with claude --continue. There’s a test mode, .beamignore support, and defaults to a 5GB workspace cap (configurable). Technically, AgentBeam uses Iroh’s QUIC-based stack for encrypted P2P transfers with NAT hole-punching (~90% success) and automatic relay fallback (~100% success) when strict NATs or corporate firewalls block direct connections. Transfers are end-to-end encrypted, use disk-backed blob storage (FsStore) and Collections for multi-file streaming, support resume on interruption, respect ignore patterns, and perform RAII cleanup of temp data. For the AI/ML community this accelerates collaborative debugging, reproducibility and handoffs of live agent state while minimizing reliance on cloud intermediaries — though users should note enterprise network restrictions and confirm security posture for sensitive data despite relay servers being unable to decrypt payloads.
