incident.io vs IncidentRelay

incident.io is a software reliability platform for investigating, responding to, and preventing incidents. Its on-call tools route alerts and support schedules, escalation, and alert insights. Teams can coordinate response from Slack or Microsoft Teams, assign roles, and automate workflows; after an incident is declared, an investigations agent analyzes signals and produces a structured root-cause hypothesis. The pricing comparison says Investigations requires Response. Status Pages can update customers as incidents progress. Listed integrations include Jira, Linear, GitHub, GitLab, PagerDuty, Datadog, Grafana, Zoom, Google Meet, and Slack. The company states that it is SOC 2 Type I and II and GDPR compliant, and that customer data is encrypted using AES-256. It also says it conducts annual third-party penetration tests and weekly vulnerability scans. Basic is free; Team is $15 per user per month with annual billing. Standalone On-call is $20 per user per month, and Pro is $25 per user per month. Enterprise pricing is by custom proposal and includes a listed 99.99% uptime SLA. Interfaces include web, Slack, Teams, mobile, and desktop.

IncidentRelay is open-source software for self-hosted on-call management and incident response. It routes incoming alerts by source, labels, severity, and team ownership, then applies team rules and escalation policies. Teams can manage schedules, shifts, rotations, overrides, and escalation chains; responders can acknowledge, resolve, silence, or escalate alerts and temporarily shelve alert groups. Versioned event rules can enrich, group, route, suppress, and automate events, with execution history showing matches and results. Documented inputs include Alertmanager, AWS SNS and CloudWatch, Grafana, Datadog, Azure Monitor, Zabbix, Sentry, LibreNMS, PagerDuty Events API v2, RMON, heartbeats, and webhooks. Notifications include chat services, email, voice calls, outbound webhooks, and browser/PWA push. The automation interface provides Swagger UI, OpenAPI JSON, route-intake tokens, and personal API tokens. On-call calendars can be exported through CalDAV and ICS. Deployment options include Docker Compose, Kubernetes with Helm, RPM packages, and manual systemd installation. The IncidentRelay plan costs nothing; it is open-source and self-hosted.
