Workers IO launches: millions of fault-injected production simulations to verify AI-written code
julianweisser · x · 2026-11-04
Dhravya Shah's team announced Workers IO to attack the slowest part of engineering: verification. As agents write years' worth of code in days, the most expensive failures still surface in production. Workers IO runs millions of simulated production scenarios across your entire system including dependencies, inside a deterministic hypervisor that injects faults like network delays, disk errors, clock skew, and process failures. Deterministic execution makes results reproducible, enabling invariant fixing and latency budgets before release.
