Jukebox OS is a deterministic flight recorder, ACID tool sandbox and time-travel runtime for multi-agent systems. Its Rust and WASI core with a Python SDK records what agents did so you can drop the needle on any frame and replay it, and it runs tool calls inside an ACID sandbox so a failed or half-applied action can be rolled back rather than left behind. It is MCP compatible and ships a live web inspector for walking through recorded runs.

Let the runtime capture every tool call and state change as it happens.
Drop the needle on any point in the recording and inspect the state the agents were in.
Run tool calls inside an ACID sandbox so a failure does not leave partial writes behind.
