How Uptime Kuma is wired
Uptime Kuma, MariaDB and the Email add-on ship together. The public hostname serves the dashboard and your status pages. Monitors, history and settings live in MariaDB.
- MariaDB holds the data
- Monitors, check history, status pages and settings live in the attached MariaDB database, with passwords generated at deploy.
- Files are on the volume
- Status page logos and browser monitor screenshots live on a 5 GB volume at /app/data, so they stay after a restart or redeploy.
- Mail goes through the Email add-on
- The Email (StackBlaze) notification uses the platform relay and your project’s sending address. Its settings follow the add-on on every restart.
- One instance, always on
- Uptime Kuma runs as a single replica that checks your monitors around the clock and serves the dashboard over HTTPS.

Common questions about Uptime Kuma
How do I sign in after deploy?
Open the public URL and sign in as admin with the password generated at deploy, shown as ADMIN_PASSWORD in the app’s Variables in the dashboard. The account exists before the app goes live, so there is no setup page to finish.
How do I get email alerts?
Open Settings, Notifications and edit Email (StackBlaze). Enter your address in To, save, and tick the notification on your monitors. It sends through the platform Email add-on, so there is no mail server to set up.
Can I get alerts in chat apps instead?
Yes. Uptime Kuma has many notification services built in, such as chat apps and webhooks. Add them under Settings, Notifications with the details from that service.
Can my users see a status page?
Yes. Create one under Status Pages, pick the monitors to show and publish it. It is public at /status/<slug> on your app URL, without a login.
Where is my data stored?
Monitors, history and settings are in MariaDB. Status page logos and browser monitor screenshots are on the app volume.
Can I use my own domain?
Yes. Attach a custom domain from the dashboard, for example status.example.com, and point your status page at it. Custom domains
What does it cost?
You pay for the compute, storage and bandwidth Uptime Kuma and MariaDB use, and for the emails it sends, not per monitor or per seat. Pricing
