Offload is a parallel test runner that distributes your test suite across multiple sandboxes, either locally or on Modal cloud, cutting test runtimes by up to 6x compared to standard local runs.

It supports pytest, cargo nextest, and vitest out of the box, plus any custom test runner through its generic default framework with configurable discovery commands.

You can configure per-group retry counts, and any test that passes on retry is flagged as flaky with a distinct exit code so intermittent failures never block your pipeline.

Yes. The local provider runs tests in parallel processes on your own machine, while the Modal provider is only needed for scaling out to remote cloud sandboxes.
