incident.io is a software reliability platform that handles on-call, incident response, investigations and status pages in one product. Teams declare and run incidents from Slack or Microsoft Teams, where roles, workflows and AI call transcription keep the response organized. Its agent starts root cause analysis the moment an incident is declared, scanning signals and returning a structured hypothesis. The Basic plan is free forever, Team costs $19 per user per month ($15 billed annually), and Pro is $25 per user per month, with on-call available as an add-on.
Engineering managers, SRE leads and on-call engineers are the core audience, and the customer list runs from fast-growing startups to large enterprises. Zendesk modernized incident response across more than 1,200 engineers, and companies such as Linear, Airbnb and Fin appear in customer quotes. Smaller teams can begin with the free tier, growing teams move to multi-team on-call and workflows on Team, and enterprises add access control, security and compliance, a dedicated success manager and a 99.99% uptime SLA.
Typical scenarios include routing an alert to the right person with AI filtering out noise, opening a dedicated Slack channel and call when an incident starts, letting an agent propose a root cause from telemetry, deployments and past incidents, and posting automatic updates to a status page so customers stay informed. After resolution, teams run postmortems with custom post-incident flows and review trends in Insights dashboards. Standalone on-call at $20 per user per month suits teams that only need scheduling and escalation.
