Where IsDown is stronger

  • Broader coverage — 6,320+ vendors.
  • Team features and integrations like Datadog and PagerDuty, plus granular alert filtering by component and severity.
  • Hosts your own status pages and can monitor your own endpoints.

Where Outage Observer is different

  • Free, with no account. IsDown is paid after a 14-day trial.
  • Official feeds only — no crowdsourced signals. IsDown blends official and crowdsourced data; we don't, so a wave of user reports never triggers a false “down”.
  • Channels you already use, free: Telegram, Slack, Discord, browser push, RSS, a native Mac app, and an installable web app.
  • Privacy-first: no accounts, no tracking, your watch list stays on your device.

Which should you use?

Choose IsDown if you're a team that needs more vendors, enterprise integrations, or to host your own status page.

Choose Outage Observer if you want free, no-signup, official-source-only alerts for the services you depend on.
