All Quiet vs IncidentRelay

All Quiet is an incident management and on-call platform for engineering teams. It sends interactive alerts through iOS and Android apps, push notifications, SMS, phone calls, email, Slack, and Microsoft Teams. Smart alert handling routes, groups, and deduplicates incoming alerts from more than 50 monitoring tools, while escalation tiers reroute alerts that remain unacknowledged. Incident reporting records timelines, post-mortems, MTTA, and MTTR. The maker lists more than 50 integrations, including AWS CloudWatch, Datadog, Grafana, Prometheus Alertmanager, Sentry, Jira, and Linear. Native mobile apps support incident collaboration, iOS Critical Alerts, and Android Do-Not-Disturb override. All Quiet states that it is ISO 27001 certified and GDPR compliant, with EU and US data regions. Standard costs $4.99 a month per user and retains incidents for six months. Pro costs $9.99 a month per user with 12-month retention. Enterprise pricing and retention are custom, and a 14-day trial is listed.

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.
