ilert vs IncidentRelay

ilert combines alerting, on-call management, incident response, and status pages in one incident management platform. Responders can receive push, SMS, voice-call, and messenger alerts, then acknowledge them with one click without logging in. Teams can build follow-the-sun rotations, swap shifts, and manage overrides from the mobile app. Incident tools include severity settings, parallel escalations, and incident commander assignment. Status pages can be public, private, or tailored to an audience. AI SRE examines logs, metrics, traces, and change data to provide a root-cause hypothesis, supporting evidence, and a proposed action for human review. Integrations cover monitoring, ticketing, chat, and collaboration tools, alongside Email, SMS, Heartbeat monitoring, and a custom Event API. ilert is available on Android, iOS, web, and through an API. The Free plan is free for up to five users and one status page, with 100 SMS/voice notifications monthly; that quota is a hard limit, and notifications stop until reset unless the account moves to a paid plan.

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.
