Workers IO launches to verify AI-written code with millions of fault-injected production simulations
julianweisser · x · 2026-11-06
Workers IO launched to tackle the slowest part of engineering in the AI coding era: verification. It 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.
The team's stated goals: minimize compute spent finding customer-relevant failure scenarios, with zero false positives. In a first customer case, it surfaced 10+ critical/high-severity issues for an infra company serving tens of millions of daily requests — all confirmed legitimate after just a few hours of simulations.
