Claude Sessions CLI (claude-sessions) is an open-source, high-performance systems utility developed under the SpaceCorps engineering collective. It solves a common pain point experienced by software engineers and technical teams: when switching accounts or organizations in the official Claude Desktop application, all previous Code-tab sessions vanish from the sidebar despite still residing safely on your workstation's disk.
Modern developer tools should be deterministic, instantaneous, and respect user privacy. We engineered claude-sessions in pure Rust to provide sub-millisecond execution times without managed runtime bloat, external node dependencies, or cloud network latency.
Safety is the primary invariant of claude-sessions. The CLI only ever performs non-destructive file copies. Source session records and project worktrees are never deleted, altered, or moved. Furthermore, the tool provides automated skip logic for sessions already present in the target profile, tombstoned items, and missing worktrees, making repeated runs completely safe and idempotent.
Software development sessions frequently contain confidential intellectual property, API keys, proprietary prompts, and internal architecture diagrams. claude-sessions runs entirely offline on your local machine, performs zero outbound network requests, and requires zero cloud credentials.
