Everything you need for distributed testing
Built for engineering teams that need scale without sacrificing control.
BYOC Infrastructure
Tests run on your AWS account. Your data never leaves your infrastructure. Complete sovereignty over every trace, log, and test result.
Parallel Execution
Distribute tests across EC2 Spot instances. Run 1000 tests in minutes, not hours. Pay only for the compute you use.
Playwright Traces
Every test generates a full Playwright trace. Debug failures with timeline, snapshots, and network logs — right in the dashboard.
Smart Sharding
Automatic test distribution across workers. No manual configuration required. TraceLoom detects your test suite and distributes optimally.
Real-time Monitoring
Watch test progress live. Fleet cost tracking to 4-decimal precision. Know exactly what every run costs before it finishes.
