Watch every container,
database, and endpoint
— in one place.
Monitoring built for teams that ship fast and don't want to babysit Datadog. Lightweight Rust agent, plugin-based core, one dashboard for everything.

Three things, one dashboard.
No configuration sprawl. No agent fleet. Drop in one binary, register the targets you care about, watch them.
Docker
Live container events, restarts, OOM detection, CPU and memory metrics from the local socket.
Databases
Postgres, MySQL, Redis. Connection probes, slow-query insights, replication lag.
HTTP endpoints
Latency, status codes, error rates. Public APIs or internal services behind a firewall.
Read-only by design.
We don't host your database. We don't ask you to copy data anywhere. For database monitoring, you give us a user with the smallest footprint possible — and we pull metrics, never your data.
-
01
One read-only user
You create a user with
SELECT-only access to system catalogs and built-in stored procedures —pg_stat_*,INFORMATION_SCHEMA,performance_schema. Nothing else. -
02
No access to your tables
The user can't read application schemas, can't see row data, can't write anything. We literally cannot view what's in your database.
-
03
Metrics only — over your network
We pull connection counts, slow-query stats, replication lag, cache hit ratios. The connection runs from your environment to ours; nothing inbound is required.
Why we're building this.
We were fed up juggling a different tool for every layer — one for container logs, another for database health, a third for uptime checks, a fourth for alerts that never quite worked. So we built Sentinel to put all of it in one place. Watch a Docker container and inspect its logs and crash pattern in the same view. Probe Postgres, MySQL, or Redis for slow queries and connection drops without spinning up a second dashboard. One timeline of what failed, when, and why. Pricing is pay-as-you-go — start free, pay only for what you actually monitor. Some of the building blocks stay open source so you can see exactly what runs on your machines.
