Kestrel

Features

Everything you need to run infrastructure with confidence

Start with servers, websites, APIs and Laravel applications. Grow into dependency mapping, backups and business-level monitoring.

Server monitoring

A single lightweight agent per VPS reports CPU, memory, disk, network, load and critical processes every 15 seconds. Outbound HTTPS only, no remote shell.

Website & API checks

HTTP status, response time, DNS, SSL expiry, redirects, response body and JSON assertions — with failure confirmation so one blip never pages you.

Laravel-aware

An optional Composer package watches queue workers, failed jobs, the scheduler and application health — the things generic uptime tools cannot see.

Incidents that explain themselves

Failures are confirmed, de-duplicated and tied to the right server and service. Every incident keeps a full timeline from detection to recovery.

Alerts where you work

Email, Discord and Slack today. Severity-based rules, repeat reminders until acknowledged, and recovery notices when things are healthy again.

Databases & queues

Track MySQL, MariaDB, PostgreSQL and Redis with read-only credentials. Know about connection exhaustion before your users do.

Built for fleets

Manage 5 or 500 servers per organization with environments, tags and per-team roles. Real-time updates, no page reloads.

Secure by design

Strict tenant isolation, encrypted secrets, signed agent releases, revocable credentials and SSRF-hardened external checks.
