What a complete post-mortem includes
The generator produces every section below — the structure used by high-performing SRE and DevOps teams for blameless incident reviews.
Header & metadata
Title, date, severity, detection and resolution times — the at-a-glance facts.
Summary
A 2–3 sentence overview anyone can skim, from exec to engineer.
Customer impact
Who was affected, how badly, and how many — quantify it.
Timeline
Timestamped events from detection to resolution.
Root cause
The underlying cause, not just the surface symptom.
Resolution
What you did to fix it and how you verified recovery.
Action items
Owned, dated follow-ups so it doesn't happen again.
Lessons learned
What went well and what went wrong — blamelessly.
Write the post-mortem while the timeline is still accurate
The hardest part of a post-mortem is reconstructing exactly when things happened. If your monitoring already records detection, escalation, and resolution timestamps, half the timeline writes itself. Alert24 incident alerting captures that record automatically, and the blameless post-mortem culture guide covers how to run the review itself. To size the incident, pair this with the SLA & downtime calculator and the error budget calculator.
Frequently asked questions
What should an incident post-mortem include?
A good post-mortem includes a header with severity and timing, a plain-language summary, quantified customer impact, a timestamped timeline, the root cause (not just the symptom), the resolution and how recovery was verified, owned-and-dated action items, and blameless lessons learned. This generator produces all of those sections.
What is a blameless post-mortem?
A blameless post-mortem focuses on the systems and conditions that allowed an incident, not on punishing individuals. The assumption is that everyone acted reasonably with the information they had. That psychological safety is what makes people share what really happened, which is the only way to actually fix root causes.
Is this post-mortem template free?
Yes. The generator is completely free, requires no signup, and runs entirely in your browser. You can export the finished post-mortem as a Markdown (.md) file or copy it to your clipboard to paste into Confluence, Notion, GitHub, or any doc tool.
Can I use the output in Confluence or Notion?
Yes. The output is standard Markdown, which Confluence, Notion, GitHub, GitLab, Linear, and most wikis import or render directly. Copy it with the Copy button or download the .md file and import it.
Stop reconstructing timelines from memory
Alert24 detects incidents, timestamps every escalation, and keeps your status page current — so your next post-mortem is mostly written before you open the doc.
