OrcaRouter open-sourced OrcaReplay, a record-replay-fork engine for agent runs
Announced via PRNewswire on 2026-09-02T12:38Z and confirmed on GitHub at Continuum-AI-Corp/OrcaReplay (79 stars, 21 forks, created 2026-08-29, last pushed 2026-09-03T11:15Z). It records an agent execution and lets you replay, fork and debug from any step, and is agent-agnostic and model-agnostic with replay data able to stay local, which the announcement pitches at privacy-sensitive debugging, evaluation and security workflows. Forking from an arbitrary step is the piece missing from trace-only observability tools: you can change one decision mid-run and see what the rest of the run does.
