Found Better Pagerduty Alternative

FluidifyAI released Regen, an open-source alternative to PagerDuty and Grafana OnCall, offering unlimited alert noise reduction, on-call schedules, and AI-powered incident summaries with self-hosting options. The tool supports BYO AI keys, 1-click imports from competitors, and claims sub-10ms webhook ingestion with zero-downtime deploys.

Reproduce yourself: make load-test and make chaos-db . Full methodology in docs/RELIABILITY.md . Zero-downtime deploys — rolling restarts drain in-flight requests before pod shutdown SIGTERM → 30 s drain → exit PostgreSQL HA — Patroni manages automatic primary election; HAProxy re-routes to the new primary within one health-check interval 3 s . No app restart, no config change. Redis Sentinel — 3-node quorum detects primary loss; workers reconnect to new master automatically Kubernetes-native — HPA, health-gated rolling deploys, resource limits out of the box Webhook flood protection — rate limiter returns 429 before the DB sees load spikes; validated at 3,917 RPS with zero OOM events Full observability — /metrics Prometheus + pre-built Grafana dashboard in deploy/grafana/ curl -X POST http://localhost:8080/api/v1/webhooks/prometheus \ -H "Content-Type: application/json" \ -d '{ "receiver": "fluidify-regen", "status": "firing", "alerts": { "status": "firing", "labels": {"alertname": "TestAlert", "severity": "critical"}, "annotations": {"summary": "Test alert from curl"}, "startsAt": "2024-01-01T00:00:00Z" } }' An incident is created automatically. If Slack is configured, a dedicated channel appears within seconds. Connecting Slack:Regen uses Slack's HTTP Events API signed POST to /api/v1/slack/{events,interactions,commands} — not Socket Mode. Local dev needs a public tunnel ngrok . Full setup, including the three Request URLs and troubleshooting, is in docs/getting-started/connecting-slack.md . Authentication : bcrypt cost 12 , timing-safe comparison, 5-attempt account lockout, HTTP-only SameSite=Strict session cookies No SQL injection surface : All database access uses GORM parameterized queries — no raw string interpolation Webhook verification : Slack HMAC-SHA256 + replay protection , Teams RSA/OIDC , CloudWatch RSA + SSRF-safe cert validation Rate limiting : Redis Lua script enforcing three tiers — 10/min on auth endpoints, 120/min unauthenticated, 600/min authenticated Security headers : CSP, HSTS 2 years , X-Frame-Options, X-Content-Type-Options, Permissions-Policy on every response Container hardening : non-root UID 1001, read-only filesystem, all Linux capabilities dropped CORS : explicit allowlist via CORS ALLOWED ORIGINS ; dev-only fallback to localhost Frontend : no dangerouslySetInnerHTML , no secrets in bundle, session token never accessible to JavaScript Review the Production Security Checklist — TLS, PostgreSQL password, Redis auth, and CORS origins for prerequisiste checklist.
