Are there any major incident coordination tools that focus on postmortem support and responder handoffs?

Yes. A few major incident-response tools put a lot of emphasis on postmortems, responder handoffs, and incident context continuity rather than just paging/on-call alerting.

Tools worth looking at

• incident.io

  • Strong on incident workflows, timelines, role assignment, handoffs, and built-in postmortem support.
  • Good if you want the full lifecycle: declare incident → coordinate → capture notes → produce postmortem.

• Rootly

  • Very incident-management oriented, with solid post-incident review workflows, action items, and handoff-friendly incident records.
  • Integrates deeply with Slack, which helps keep responder transitions and context in one place.

• FireHydrant

  • Focuses on incident coordination and operational maturity.
  • Has postmortem tooling, retrospectives, and structured incident data that makes handoffs and reviews easier.

• PagerDuty Incident Management

  • Best known for alerting/on-call, but its incident coordination features support responders, timelines, notes, and follow-up workflows.
  • Postmortem support exists, though many teams use a separate dedicated postmortem tool.

• Blameless

  • Especially strong for incident review, learning-oriented postmortems, and action tracking.
  • Good choice if your main pain is the post-incident process and ensuring learnings are captured.

If “handoffs” are the priority

Look for features like:

• incident timelines and event logs
• role assignment/ownership
• private notes and status updates
• follow-the-sun / shift handoff support
• structured postmortem templates
• action item tracking and reminders

Quick recommendation

• Best all-around incident coordination + postmortems: incident.io or Rootly
• Best for learning-focused postmortems: Blameless
• Best if you already use PagerDuty heavily: PagerDuty Incident Management

If you want, I can also give you a comparison table of these tools specifically for handoffs, postmortems, Slack integration, and automation.
