Self-hosted alternatives to UptimeRobot
UptimeRobot pings your endpoints on a schedule and alerts when they stop answering. The monitor here does the same and keeps the history — provided you give it somewhere reliable to run.

The bill
The subscription against a server
Both figures are editable, because only you know which of them you actually pay. The server is sized from the figure the recipe recommends — the same one the catalog calls a comfortable fit on your profile — and not from the cheapest row of a price list.
Uptime Kuma asks for 1 GB of RAM, 1 vCPU and 2 GB of disk — $6 a month on DigitalOcean Basic.
The difference
- Per month
- $3
- Per year
- $36
- Over three years
- $108
Hosting it yourself is cheaper — $36 a year stays with you.
Not counted: your own time, a domain, and a backup kept anywhere other than that same server. A machine you already run costs nothing extra — set the server to zero.

Migration
What changes when you host it yourself
The data stops leaving your network, and so does the responsibility for it: backups, the restore you have actually tested, and the disk it all sits on.
Feature parity is never exact. Read what each recipe states about limitations and the smoke test before planning a migration.
The bill turns into work: updates, certificates and an eye on the release notes. The catalog shows how much of that each recipe asks for.

Guides with these applications
- A home server that earns its keepA modular home-server starter set: passwords, DNS, sync, monitoring, notifications, media and household recipes. Choose the services you need and add them gradually.
- Applications with a minimum of 1 GB RAM or lessSmall declared resource requirements for a VPS or thin client, with new metrics, notifications, notes and utility recipes. The limit applies to each application separately.
- What a Raspberry Pi can actually runA shortlist for 32-bit ARM systems, plus the newer options a 64-bit Pi can consider. Check the actual architecture test result before choosing a recipe.
- Knowing when your server stopsAvailability checks, server-resource history, notification delivery and a shared dashboard serve different jobs. Build only the layers you need and monitor from outside the server.
