Built like infrastructure
Data stays in your Hetzner
Events live on a node inside your own Hetzner project. Belvador's control plane only keeps settings and counts.
Fleet Command
One screen for every app: new issues, regressions and node health across your whole portfolio.
Traces and logs, next to the error
Send traces and logs from any OpenTelemetry SDK; Node.js, Python, Go and Java are tested. They are stored on the same node and linked to the errors they explain.
Cron, uptime and SLOs
Know when a job never ran, a URL stops answering or an error budget burns too fast. URLs are checked from Europe, the US and Asia; alerts use the same channels.
Alerts without noise
Telegram, Slack and email within a minute of a new issue — and never the same issue twice in 30 minutes.
Pricing
BetaFree during the beta. You pay Hetzner directly for your node, and Belvador will never bill per event.
