How much does it cost to switch from UptimeRobot?
The software itself is free. For server apps, the main cost is hosting: as a reference point, DigitalOcean lists a 1 GiB server at $6/month and a 2 GiB server at $12/month (checked Oct 29, 2026). Check each project's documented requirements before choosing a size. The hidden cost is time: moving your data and, for self-hosted apps, keeping up with updates and backups.
