From detect
to resolve, lined up.
Log every stage of an incident — detect, alert, triage, mitigate, communicate, resolve, postmortem — with times, severity and who acted. See detect→ack, ack→mitigate and mitigate→resolve durations, catch out-of-order stages and long gaps. Free, and nothing leaves this browser.
A working timeline you can export.
Add events with a local time, title, category, actor/role, severity (SEV-1 through SEV-4 or Info), status and notes. The tool sorts chronologically, groups by category, measures milestone durations and flags stages that appear out of order or with multi-hour gaps. A labelled fictional checkout-latency incident is loaded so you can try exports immediately.
Sample: checkout latency.
The sample walks a fictional outfitter from a synthetic latency detect through mitigate, a status-page note, resolve and a planned postmortem — so durations and exports are real before you add your own events.
Milestone durations
Detect → acknowledge, acknowledge → mitigate, mitigate → resolve, and full detect → resolve, computed from the first event in each stage.
Order & gap checks
Flags when a later stage is timed before an earlier one, and when consecutive events are four or more hours apart.
Markdown, CSV, .ics
Export a Markdown timeline, a formula-safe CSV, an optional iCalendar file of milestone moments, and JSON you can reload later.
