Show HN: Make every bug perfectly reproducible (workers.io)
13 points by chaitanyya 42 days ago
We are building a VM that helps you simulate realistic production conditions, model latencies, different interleaving, user requests, and find bugs.

Every non-deterministic property is turned into a knob you or a coding agent can control. We have helped teams perfectly reproduce support incidents and found bugs in some of the world's most well tested software (including a database).

Can you make it clear on your homepage what you have to do to use this? I.e., do I add a library to a codebase? Do I add opentelemetry to every request? Does it read my logs?

I went and tried to skim your docs here (https://workers.io/docs/quickstart) and I still don't get it. Looks like there's something around reading logs?

Thanks, we need a lot of work in the docs and the homepage. A lot of that part was very rushed.

You just need to create a simple workload - think of it like an e2e test case you care about. It can be in any language or lib. Next you need to run this test in our VM.

We then simulate 100s of realistic production scenarios like slow network, different cpu scheduling etc. and save the environments where your test case fails.

Those failing environments can be inspected, you can replay then and they will always produce the exact same result.
