The on-call shift
that never spreads
thinner.
Tocsin is an autonomous QA agent that keeps watch over your production web app. Every deploy, it re-runs the flows that matter, files fully-detailed bug tickets when they break, and only pages the engineer when a real user would actually feel it.
No SDK. No nightly queue. One deploy hook, fifty flows, zero dashboards to babysit.

An actual Tocsin post-deploy summary, shown via the public demo.
The regressions that
actually page the on-call.
Every catch produces a ticket with the trace, the network capture, the screenshot, and a one-line repro — filed into the tracker your engineers already use.
False positive suppression
Tocsin learns what your app looks like on a good day. Layouts drift, copy rotates, "DOM changed" is not a regression.
Network-aware assertions
When a checkout "succeeds" but returns an empty array, Tocsin catches it. DOM-only assertions miss half the bugs that hurt users.
Self-healing selectors
Button → button → div[role=button]. When the team refactors, Tocsin follows. Test maintenance stops being a tax.
Journey knowledge graph
Checkout is six steps in your head; in Tocsin it is a graph. When step 3 changes, step 6 stops being a mystery.
One hook in CI.
Production under watch.
Pin your critical flows
Point Tocsin at your app. It maps the user journeys that matter — checkout, auth, onboarding, billing — and learns them as a knowledge graph, so it never breaks when CSS drifts.
Wire the deploy hook
A single CI hook fires Tocsin on every ship. No nightly queue, no waiting for someone to remember to run the suite — your regression suite runs against production the moment code lands.
Real flows, not brittle snapshots
Tocsin re-runs your end-to-end suite against live environments and validates real user behavior — selectors self-heal, network calls are replayed, and DOM snapshots are the last resort, not the default.
Only true regressions page on-call
When a flow breaks in a way that would hurt a user, Tocsin files a richly-detailed ticket — trace, network capture, screenshot, repro steps — directly into Jira, Linear, or GitHub Issues. Slack and PagerDuty get paged. Everything else stays quiet.
Slots in alongside
the stack you already
trust.
Tocsin is one more signal in the observability chain — another last-mile check, not another dashboard. It files where your engineers file, pages when your team pages, and runs against the same environments your customers see.
