Local-first execution with replay semantics

Musketeer is an execution system for deterministic, replayable runs. No cloud required. Your data stays local.

Deterministic execution

Runs produce the same results given the same inputs. Every execution is reproducible.

Replay semantics

Replay past runs to debug, test, or verify. State is recorded and can be reconstructed.

Local-first

No accounts, no cloud, no network required. Everything runs on your machine.

Quick start

# Initialize a project
musketeer init
