Site Mode · websites & web apps
Find the race conditions before your users do.
Synthetic users complete real flows on your site — signup, checkout, onboarding — at population scale. Race conditions, conversion drop-offs, and broken flows surface before launch day, not on it.

What Site Mode finds
The bugs your existing tests can't see.
Unit and integration tests prove a single flow works. Oracle Bot proves a population of users doesn't break it.
- Race conditions under concurrent user load
- Conversion funnel drop-offs you can't see in QA
- Cold-start latency cliffs
- Auth flow brittleness at scale
- Inventory contention and double-booking
