Site reliability for every project your team ships.
Monita checks your team's websites and scheduled jobs, alerts the people you choose when one fails, and shows the outage on a public status page. It runs on your own server as one program with one SQLite file.

Install
- Monitors check a URL, a TCP port, a DNS name or a host by ping every 30 s to 5 min, and warn before an HTTPS certificate expires.
- Heartbeats wait for your cron jobs to call in.
- Incidents open after two failed checks or a missed heartbeat, and alert by email, Slack, Google Chat, Discord, Telegram, ntfy or PagerDuty.
- Status pages show 90 days of uptime and the updates your team posts.
- Tickets collect bug reports from the status page or from your app.
- Maintenance windows, pause and locations keep planned work quiet and check from more than one place.
- Roles, two-factor sign-in and scoped API keys let one Monita serve the whole IT department.
Click through the demo first. It runs on sample data and saves nothing.
Install
On a 64-bit Linux server with systemd, 512 MB of memory and 5 GB of disk. On Arm, use monita_linux_arm64.tar.gz.
curl -fsSLO https://github.com/PT-Perkasa-Pilar-Utama/monita/releases/latest/download/monita_linux_amd64.tar.gz
tar -xzf monita_linux_amd64.tar.gz
sudo install -m 0755 monita /usr/local/bin/monita
sudo monita setup
sudo monita service install
monita setup asks for the public URL, the mail server and the first super admin. Put Caddy or nginx in front of 127.0.0.1:7466 for HTTPS.
To try it on a laptop with Docker, create the first account (it asks for a password of at least 8 characters):
docker volume create monita-data
docker run --rm -it -v monita-data:/data -e MONITA_ENV=dev ghcr.io/pt-perkasa-pilar-utama/monita:1 admin create --email [email protected]
Then start Monita and open http://localhost:7466:
docker run -d --name monita -p 127.0.0.1:7466:7466 -v monita-data:/data -e MONITA_ENV=dev ghcr.io/pt-perkasa-pilar-utama/monita:1
The install guide covers a Docker server, macOS, Windows, upgrades and building from source.
Send a ping from a cron job
URL=https://monita.example.com/ping/<token>
if ! out=$(backup.sh 2>&1); then
printf '%s' "$out" | curl -fsS -m 10 --data-binary @- "$URL/fail"
exit 1
fi
curl -fsS -m 10 "$URL"
A missed deadline opens an incident. A call to /fail opens one at once, with the first 1 KB of the body as its cause.
Benchmark
Each tool checked 500 URLs every 60 s against one local nginx, alone in Docker on an Apple M1 (colima, 2 vCPU). Memory and CPU come from docker stats every 15 s for 5 minutes, after a 5-minute warm-up, on 2026-10-27.
| 500 checks a minute | Monita 1.1.0 | Uptime Kuma 2.5.6 | Gatus (latest, built 2026-10-23) |
|---|
| Memory under load (median) | 3.6 MiB | 236 MiB | 45.5 MiB |
| CPU, share of one core | 0.7% | 4.7% | 3.3% |
| Checks done per minute, of 500 | 500 | 464 | 500 |
| Image download (arm64) | 6.5 MB | 603 MB | 24.5 MB |
