Offload - Offload your test suite to speed up the agent loop

We built Offload after watching an agent wait 10 mins for an integration run to finish. When you're running parallel AI coding agents, the test suite is where the loop stalls. Agents queue behind a test lock or race for local resources to return flaky results. Offload is an open-source Rust CLI your agents invoke directly. It spreads your test suite across 200+ isolated cloud sandboxes. One TOML config, no test rewrites. On our Playwright suite, it took a 12 mins run to 2, at $0.08 per run.

We're open-sourcing Offload: a test parallelizer for agent fleet workflows. The primary impact of utilizing Offload should be that more parallel agents will be able to complete their work faster. This reduces the amount of time that you spend waiting for work to complete, and keeps you in flow. Some results we saw: - 345 Playwright tests: 726 sec → 120 sec (6.04x) - 5,275 mixed tests: 346 sec → 186sec (1.86x) Eager to hear your feedback and the results you see with Offload!
