Catch production failures before customers do
Ordinary tests prove the happy path. Workers IO runs the workflows your business depends on under production-like timing, network, retry, crash, and service behavior, then preserves the exact failed case so your team can fix it.
Test the risky path
Choose a workflow users rely on, like checkout, job processing, sync, provisioning, or retry recovery.
Expose production conditions
Run it when timing shifts, dependencies slow down, retries happen, crashes occur, or services return surprising responses.
Keep the failed case
Save the inputs, state, and sequence so engineers can reproduce it and verify the fix.
A new development reality
More code now reaches customers faster than ever.
AI has made code faster to write and ship. The bottleneck is no longer producing changes; it is proving important workflows still work when production behaves badly.
A new reliability problem
Tests pass, but production still breaks.
Most tests check expected behavior in clean environments. The incidents that hurt teams usually come from timing, retries, crashes, duplicate jobs, partial outages, or unexpected third-party responses.
A new way to test risk
Test the conditions that make failures expensive.
When simulation detects a failure, it captures the conditions that caused it: the request, inputs, timing, service responses, system state, and faults. Engineers can inspect what went wrong and rerun the same case to confirm the fix works.
1. Capture the failed case
Record the inputs, timing, service responses, system state, and faults that made the workflow break.
2. Reproduce it on demand
Recreate the same conditions so engineers can inspect and debug the issue without guessing.
3. Verify the fix
Rerun the captured failure to confirm the software now behaves correctly.
Built for agent-driven engineering
Give coding agents the feedback loop senior engineers need.
Agents can change code quickly, but without a reliable way to recreate production failures they guess. Workers IO gives them a captured case to inspect, rerun, and use as proof that the fix works.
Built for security reviews
Bring production-like testing to sensitive systems.
Built for teams that need SSO, encryption, audit logs, VPC support, and configurable data controls before testing realistic failure cases against production-adjacent systems.
SOC 2 Type II
Controls mapped for enterprise security review.
