Show HN: Make every bug perfectly reproducible

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)

I you would like to try it out, I am giving away $100 in free credits to first 100 signups.
