Sovereign infrastructure monitoring, hosted in France.

HTTP(S), heartbeat/cron, SSL/TLS and domain checks — alerts confirmed across two EU regions before you get paged, delivered by email, Slack, or signed webhook in under 60 seconds.

Sentinel — your watcher 24/24 7/7

HTTP(S) checks

Status code, latency, body and header assertions. Interval from 30s to 24h.

Heartbeat & cron

Your job pings us after each run. Silence past the grace period is a failure.

SSL/TLS & domains

Certificate expiry at D-30/14/7/1, invalid chain detection, domain/DNS expiry.

Multi-probe confirmation

A failure only pages you once it's confirmed from a second, independent region — no single-region false positives.

Alerting

Email, Slack incoming webhooks, or a generic HMAC-signed webhook — routable per check.

Organizations & roles

Owner/admin/member, per-org API keys, team invitations.

Tower — status pages & incident management

A public status page for your infrastructure. A check going down auto-drafts the incident; your team takes it from there — post updates, merge components, close it out.
