Your parallel agents needed scalable test coverage yesterday Introducing Offload: a Rust CLI that spreads your test suite across 200+ Modal sandboxes, freeing your CPU to keep your agents shipping. On our Playwright suite, it took a 12 min run to 2, at $0.08 a run

Open-source (of course). Drop-in for pytest, cargo-nextest, vitest. One TOML config. Try it on your agents

Offload continues our march to better, open software that benefits people like you. At Imbue, we believe open agents are foundational. See more of our work @GitHub

@modal Thank god for Offload, some of our test suites were badly slowing down the agent iteration cycle 😭

@modal Made a File City Tour of Offload A visual map + narrated walkthrough of the open-source Rust CLI that spreads test suites across 200+ @Modal sandboxes for ultra-fast parallel testing Great work! @imbue_ai

@modal Congrats to the Offload team for shipping this! It took a lot of ingenuity to get it run this fast.

@modal can't believe how quickly we are launching new products 😮

@modal can’t keep up with all the product launches! way to go @404Cause

@modal @grok is this true

@modal Speed your tests up, free your CPU, keep shipping 😎

@modal congrats to the Offload team!!

@modal This thing is absurdly fast

@modal super fascinating. Is it cloning the repo to every sandbox through the docker image?

@modal The parallelized speed is so impressive! I'm curious about optimizations around parallel agents, how often they should run self-tests to check if they're on the right track and if the entire test suite needs to be rerun each time.

@cinxinwei @modal Offload exists to pass that decision along to you as the developer. In the past, integration tests on large projects took too long for agents to run them meaningfully often. We're still working internally to calibrate how often we run our integration tests in the agent's loop!

@modal LOVE how fast it makes tests run

@modal Incredible.

@modal That’s quite expensive 😀

@modal @grok whats this?
