Workers IO simulation platform
Deterministic-simulation testing platform that runs a customer's system unmodified in virtual machines, searches millions of interleavings, faults and timings for the conditions that break its stated requirements, and returns every failure as a reproducible case with its injected faults and execution trace; a coding-agent feedback loop verifies each agent change under the same scenarios. Professional is $2,500 per month with 2,500 simulation hours and $3.60 per extra hour; Enterprise is a custom annual contract.

Security page (browser read 2026-10-22, updated July 4, 2026) says customer data is encrypted in transit and at rest. It and the home page also show a SOC 2 Type II badge, worded as policies and controls that support SOC 2 compliance and are verified by an independent auditor, so no certification is recorded; zero data retention is listed as a default for workload data without a contractual statement, so it is left unknown.
