Workers IO launches: deterministic fault injection to verify AI-written code

Founder chaaai announced Workers IO, targeting the slowest part of modern engineering: verification. AI agents can now write a year's worth of code in days, but validating it still takes months of effort — and the costliest failures surface in production.

Workers IO runs millions of simulated production scenarios on your entire system, dependencies included. Simulations execute in a deterministic hypervisor that injects faults like network delays, disk errors, clock skew and process failures; deterministic execution means every failure replays exactly. Julian Weisser amplified the launch.
