Best incident postmortem software: Complete guide for 2026

Incident postmortem software automates the process of analyzing system outages by capturing real-time data during incidents, thereby eliminating the substantial time engineers typically spend reconstructing events from memory and logs. These platforms, such as incident.io and Rootly, integrate with tools like Slack, Datadog, and Jira to automatically draft postmortems, allowing teams to focus on resolving the root causes rather than documenting them. The software supports continuous improvement by providing analytics and insights, such as Mean Time To Resolution (MTTR) trends, which help teams identify patterns and prevent future incidents. Security features are also crucial, especially for regulated industries, to ensure sensitive data remains private. While some tools are designed for Slack-centric teams, others like Atlassian's Jira Service Management cater to organizations already using their ecosystem, offering flexibility depending on team size, incident volume, and existing workflows. The manual option, using tools like Google Docs, may suffice for small teams with infrequent incidents but becomes inefficient as incident volume increases.
