Notifier

Notifier とは？

We built Notifier because we're bootstrappers who wanted simple, affordable uptime monitoring. Add your URL, pick how you want to get notified, done. If your site goes down, we alert you via email, SMS, phone call, or Slack within seconds. Every plan, including free, comes with SSL monitoring so an expired cert never takes your site down. Free plan: 10 monitors, 5 status pages, no credit card, no catch. Built by a small self-funded team since 2018. Setup takes 30 seconds.
