Autonomouson-call,end to end.

Tocsin detects, triages, and resolves production incidents around the clock — paging the right responder, running the runbook, posting the status update, and drafting the postmortem. Without waiting for a human in the loop.

How it works

The agent owns the incident — from the first alert to the final postmortem.

Most teams lose hours between “alert fires” and “a human knows what to do.” Tocsin collapses that gap, and most of what comes after it.

01 · Why teams switch

Reliability without the AI tax.

Every Tocsin tier ships with the full agent stack. The features competitors gate behind enterprise add-ons — RAG over your runbooks, in-Slack remediation, draft postmortems — are in the plan you actually buy. Mid-market and growth-stage teams get the same autonomy as the Fortune 500, on the same day they sign.

Every tier
no add-ons
  • Autonomous triage & runbook execution
  • Slack-native incident threads
  • RAG over your wiki + repos
  • Draft postmortems
  • PagerDuty / Datadog / Sentry / GitHub
  • Team seats based on rotation size

02 · Why teams stay

One Slack thread. One source of truth.

The incident lives in a Slack channel, not in a vendor dashboard nobody opens. PagerDuty pages, Datadog graphs, Sentry traces, and the relevant GitHub PR all hang off that thread as collapsible cards. When the alert clears, the channel archives itself with a postmortem already drafted at the bottom.

03 · Why teams leave OpsGenie

A clean migration, before the 2027 sunset.

Tocsin imports schedules, escalation policies, and services on day one. Agent mode and Slack-native UX mean your on-call engineers do not have to relearn the tool while they are being paged. Most teams are fully cut over in a single on-call rotation.

Capabilities

Everything an on-call rotation needs, in one agent.

None of these are add-ons. They ship with every tier.

Capability 01
Tier-1 triage, on autopilot
Agents ingest the alert, read recent history, pull runbooks from your wiki, and decide whether it is a real incident — usually before a human even sees the page.
Driven by service ownership, not rotation defaults.
Capability 02
Right responder, every time
Pages routed by service ownership and who last touched the code — not by a stale rotation CSV. Quieter nights; less "why am I getting this?".
Driven by service ownership, not rotation defaults.
Capability 03
Runbooks that actually run
Tocsin executes the documented steps, verifies the result, and only escalates when it cannot. You keep the playbooks; we stop making you the executor.
Driven by service ownership, not rotation defaults.
Capability 04
A clean handoff, not a cliff
When a human takes over, they inherit the full timeline, the diffs Tocsin tried, and a draft postmortem — no "what happened so far?" at 3 AM.
Driven by service ownership, not rotation defaults.

Modes of operation

Match the autonomy to the risk.

New service we are still learning? Run in shadow. Mature prod with a good runbook? Autopilot. The mode is a per-service setting — not a billing gate.

Tocsin triages, executes the runbook, and posts the resolution. The on-call hears about it after the alert clears.

A real incident

Six minutes, end to end.

Tocsin-owned throughout. The on-call reads the postmortem at standup, not at 3 AM.
