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, Telegram, Slack, Discord, or signed webhook in under 60 seconds.

Sentinel — your watcher 24/7

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

Organizations & roles

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

Archer

Embed a live status badge — ring or 30-day bar, light or dark — on your own site.

Alerts you can audit

Every check keeps its own delivery log: what was sent, to which channel, and — the part nobody else shows you — what was skipped, with the reason. A monitor that quietly fails to page you is worse than no monitor.
