Tentang Uptime

Uptime checks your websites and services around the clock and writes to you as soon as something stops responding, and again when it is back. Uptime is developed and run in Austria.

What Uptime checks

• HTTP and HTTPS: a response with status 200 to 399 counts as up; anything else, and any timeout, counts as down.
• TCP: whether a connection to a host and port can be opened, for example for mail servers or databases.
• Ping and DNS: whether a host answers and whether a name resolves.
• You decide how often: every minute on the free plan, down to every 30 seconds on larger plans.

How we build Uptime

• No passwords. You sign in with a one-time code by email; there is no password that could be stolen or reused.
• An open interface. Monitors can also be managed through the API, with your own API keys and a public description at /api/openapi.yaml.
• Recognisable checks. Every request carries its own user agent, so you can tell it apart from real visitors in your logs.
• In your language. The interface is available in 13 languages, the public pages with their own addresses per language.
