Observability without the bill shock
Metrics, errors and on-call — from €2 a month
Vigilly is the simple, cheap alternative to Datadog, Sentry and PagerDuty. Ship metric dashboards, deduplicated error tracking and on-call alerting — from €2 per host a month, all tied to your GitHub repo. You pay the p99 of hourly hosts, so autoscaling spikes don't count.
Works on every device — phone, tablet and desktop. Works with OpenTelemetry, Datadog, Prometheus and Sentry SDKs. Try it without a card — hosts show a live data sample until you add one.

Everything you need to watch production
Metrics & dashboards
Push metrics over the Datadog or Prometheus protocol and build Datadog-style dashboards and widgets.
Deduplicated errors
Sentry-compatible error tracking that uses AI to group every occurrence of a bug and charts the last 7 days.
On-call & alerting
Teams, schedules and escalation policies that page the right person over SMS, voice, push and email.
Tied to your repo
Every service links to a GitHub repository, so metrics, errors and alerts all point back to the code.

How it works
Register a service
Create a service and link its GitHub repo — metrics, errors, traces and logs are all ready to receive from the start.
Send your data
Point your Datadog agent, Prometheus remote-write or Sentry SDK at the service's ingest key.
Get alerted
Set thresholds and on-call schedules — Vigilly pages the right person the moment something breaks.

Frequently asked questions
Yes. Vigilly ingests OpenTelemetry (OTLP) traces, metrics and logs, so you can point your existing OTel exporters straight at it — plus the Datadog and Prometheus protocols for metrics.
Point your Sentry SDK at your organization's DSN for exceptions, and export OTLP traces, metrics and logs using a substrate API key you create in Settings — your components (apps, databases, queues, caches) appear automatically from each service.name.
Each signal is billed cheaply per host, per month — the p99 of hourly concurrent hosts, so short autoscaling spikes aren't punished — and on-call is a flat price per team. Without a card you can still try it: new hosts show a live data sample for free until you add one.
Retention is fixed per signal server-side — shorter for high-volume traces and logs — and every service's data is isolated to your organization with row-level security.
