Know your site is down before your customers do

Get notified when things actually go down.

Monitor with confidence

Everything you need to be sure that your website is running smoothly

Configurable Uptime Monitoring

I love when I get alerts for the dozens of client sites we manage, and the site isn't actually offline.

— No one, ever.

Your people should only get alerts for things you actually care about. OnlineOrNot lets you configure your monitoring in several ways to ensure your uptime monitoring isn't a distraction.

Text Search

Want to detect when your page stops showing certain text? OnlineOrNot can search your page for text to catch error pages that don't send error codes.

Configurable Alerts

You don't want alerts for sites that aren't really down for everyone. Configure retries, and how many minutes of downtime to wait before sending an alert.

Fast Alerts

Getting alerts hours after your site goes down isn't great. We use email deliverability best-practices so your alerts get delivered, fast.

Alerts where you need them

Get notified when your site goes down, and when it comes back via Email and Slack. Alerts via SMS and phone call coming soon.

Your users could love your page speed.

Play, as a team

Keeping the lights on is a team effort. OnlineOrNot is designed for teams in mind.

Bring the whole team

Monitoring is your whole team's job, not the responsibility of just one person. Bring your whole team at no extra cost.

Alerts where you need them

Notify a single person via email, or let your whole team know via Slack.

Tired of unreliable, slow, extremely "enterprise software"-feeling monitoring apps, I built OnlineOrNot to get false-positive-free alerts whenever your pages become unreachable.
