Our story
A slow site usually has a plain reason you can read in its headers.
I'm Johnny Mobley. I started building systems for other people in 2000, when I was 16, and I've been doing it ever since. Along the way I automated most of my own work, and the tools I built for myself became these companies. Each one runs on rules I wrote down, not on paid AI calls, which is why it can cost so little.
When a page is slow, the first questions are simple: how long until the first byte arrives, and is the page allowed to be cached at all. I built Warpdrive to answer those from a live request and tell you in plain words what to change.
It measures from one place, right now. It isn't a benchmark from many cities and it doesn't watch your site around the clock.
What works today
- Measures a URL's time to first byte and reads its caching rules, with plain suggestions
- Checks whether a domain answers right now and how fast
What it doesn't do yet
UptimeRobot still does things Warpdrive doesn't:
- Checking your site on a schedule and alerting you when it goes down.
- Tests from many locations.
- Status pages.
- Alerts by email, SMS, Slack or webhook.
