Klaxon — Unified alert aggregation
Start free Free tier available — no credit card required

Alerts come from Uptime Kuma, Grafana, Datadog, AWS, and three other places — every tool with its own Slack channel, email thread, and SMS sender. Klaxon pulls them into one feed, deduplicates the noise, and routes by severity so the real pages actually reach you.

Replace Opsgenie at a fraction of the cost. Stop missing real alerts inside a flood of duplicates.

klaxon.naptownlabs.dev — unified feed live
Uptime Kuma — api.example.com DOWN critical slack + sms
Grafana — CPU > 90% on web-01 warning slack
Custom webhook — deploy failed on staging warning email
Uptime Kuma — api.example.com UP resolved slack

What you get

Universal ingestion One webhook endpoint for everything — Uptime Kuma, Grafana, Prometheus, Datadog, or any custom script that can POST JSON.
Smart routing Rules engine lets you send critical alerts to SMS + Slack, warnings to email, and info events to the log. You define the logic.
Deduplication The same alert firing 50 times sends one notification, not 50. Grouped summaries instead of a flooded inbox.
Escalation chains If a critical alert goes unacknowledged for 5 minutes, escalate to the next person on the on-call list. No missed pages.
On-call schedules Rotate through team members automatically. Set hours, define overrides, and let Klaxon handle who gets woken up at 3am.
Alert history Full searchable log of every alert, acknowledgment, and resolution. Reconstruct any incident timeline after the fact.
