orch8 play · WebAssembly · virtual time

Run a workflow without running a server.

The same strict decoder and expression engine as the Orch8 server, compiled to WebAssembly. Days of delays finish in milliseconds; HTTP, LLM and worker steps are recorded instead of called, and you can mock their answers.

This is a dry run, not durable execution — no crash recovery, workers or real I/O. For the real thing, start the local quickstart or try the hosted sandbox.
