In their own words
IncidentRelay
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.
PagerTree
PagerTree helps teams share on-call responsibility and respond to incidents. Its scheduler supports rotations, overrides, reminders, calendar sync, and public, private, or password-protected schedules. Escalation policies allow unlimited layers, configurable timeouts, repeated alerts up to three times, and reassignment. Notifications can arrive by push, email, SMS, voice, WhatsApp, or Slack. PagerTree can aggregate and deduplicate similar alerts, with aggregation periods configurable from 15 minutes to 30 days. Integration options include email, webhook, and custom webhook. Single sign-on uses SAML 2.0 and supports identity providers such as Azure, Okta, and Google. PagerTree says data is encrypted at rest with AES-256, communications use SSL/HTTPS, and encrypted database backups run hourly. Basic costs nothing for up to five users and two teams, with three months of data retention. Pro is $15 a month per user; Elite is $19 a month per user. SMS and voice coverage varies by country.
