Where we differ
- No ads. The consumer site stays free and ad-free. Business plans pay for it.
- We check for ourselves. User reports matter, but they arrive late and are easy to spam. We also run our own checks and read official status feeds. 仕組み.
- “Is it me?” Every status page can test your own connection, so you can tell whether a problem is yours or everyone’s. Also try インターネットが落ちてる？
- Free tools. Free alerts, Slack/Discord/webhook alerts, 稼働率ランキング, the API and the MCPサーバー.
