See a caught regression — Tocsin demo

Interactive demo · no signup

See exactly what Tocsin catches the second a deploy breaks something.

Watch three real user journeys auto-rerun the moment a deploy lands. Two pass clean. The third hits a regression on its last step — and Tocsin files the bug, with the failing step, expected vs. actual, and a replay ready in your hands.

Bug ticket #4711

Onboarding › save preferences
Preferences form posted with a stale schema after the deploy; the server returned 422 and the UI swallowed the error into a generic toast. The submit button kept firing with the same shape, so a real user could not progress past step 3 of onboarding.
