Kynth Postmortems vs incident.io
The writeup shouldn't cost per responder.
incident.io is the incident-response platform a lot of great teams run on: declare in Slack, coordinate roles and statuses, page on-call, and — on the Pro plan — draft post-mortems with an AI-native editor. It's transparently priced per user, $19–$25 a month per responder, with on-call as an add-on and the richest post-incident tooling gated to Pro. Kynth Postmortems does the after part only: it reads the incident channel and the commits, reconstructs the timeline, drafts the blameless writeup, and files the action items in Linear so the fixes actually happen — $19 a month flat, no per-seat meter. Here's the honest comparison.

No success fee, no usage meter, no demo call. 30-day money-back guarantee.
Ten responders on incident.io Pro is 10 × $25 = $250 a month — before the on-call add-on at another $20 per user. Kynth Postmortems is $19 a month flat no matter how many engineers touch the incident, with a 30-day money-back guarantee.
The honest recommendation
- You want the whole incident lifecycle in one place — declaring, coordinating, paging on-call, and status pages — not just the writeup at the end.
- Your team is small enough that per-user pricing stays cheap, or the free Basic tier covers you while you grow into it.
- You want customizable post-incident processes and incident analytics across the org — that's Pro-tier incident.io, and Kynth Postmortems doesn't try to be it.
- Your incident response already works — you just never get the postmortem written, and you want the timeline, writeup, and action items done without adopting a platform.
- You don't want the writeup tool metered by responder count — $19/mo flat covers the whole team, and the best post-incident drafting isn't gated behind a higher tier.
- You want the price up front — it's printed here, the live demo needs no account or card, and the 30-day money-back guarantee covers the rest.
