The last product I built, Sqoot, had a lot of moving parts. We had three databases, a search server, an API, website, and a deal importing system. It’s a marvel that it worked at all! The truth is that it went down pretty frequently. Sadly, our customers were often the first to find out even though we went to great lengths to monitor our apps.
After Sqoot, I briefly worked at TaskRabbit. Because we had an operations team I didn’t have to think about whether or not our code was running. But I did still have to worry about the code itself: thousands of lines scattered across a bunch of apps. We wrote lots of tests to prevent bugs. The slowest tests were our integration tests. These tests actually boot up a server and clicked around the site in a browser like a customer would. These tests were so frustratingly slow that Rob Robbins and I dreamt up Specford. And still anytime someone on my team wanted to push a change, we’d wait 15-20 minutes for the tests to run. Our test suite was the biggest adversary to our speed.
Paradoxically, our code still broke in production. If you want to know with 100% confidence that things are “up,” you just need to check production. There are a few services that will do this kind of monitoring for you but they’re either hard to use, expensive, or both. I want a service that’s affordable and well designed. So I’m building it.
Canary is an uptime monitoring service. Canary tells you when things go wrong before anyone else does. Currently Canary will monitor a URL and send an alert if the URL doesn’t respond or responds unsuccessfully. There are no usage limits or tiered subscriptions; $5/mo gets you everything.
I’ve teamed up with my friend and previous co-founder, Brandon. We’ve built great things in the past and are really excited to build out all the ideas we have for Canary.
