Monitor websites, APIs, and cron jobs
in just 30 seconds.

When my websites break, I used to find out only after several days of downtime - from angry clients.

OnlineOrNot tells me immediately when I make a bad deployment, simply and beautifully.

— a freelance developer

We pitch our website to investors and influencers all the time. If the website is down, we look like amateurs.

We know our website is online before these important meetings thanks to OnlineOrNot.

— early start-up founder

Sometimes our app server goes down when pushing changes from dev to prod, and as the founder I don't always notice.

OnlineOrNot helps us catch these issues hours before our customers do.
