The most frustrating bug I ever fought only showed up on a remote device. I was working on an AngularJS component, and for some irritatingly-unknown reason, it would not render on a Samsung Android device. One specific device. It just happened to belong to someone really important.

Debugging remote devices sucks because you don’t have access to your tools. You can’t just open the inspector and dive in–you have to build and deploy custom debugging code. Then do it again with what you missed. And again.

We built RemoteJS to help with this--to help connect easily with troublesome remote browsers with the tooling you'll need to understand what's different there and debug it.

The service is based around the TrackJS agent, with some extensions in place to grab screenshots and execute commands. It establishes a websocket connection to a simplified debugger application, built in React.

Nothing is stored as part of the service, so it's all very inexpensive to run. A few folks might have put us on production sites today, which was a fun load test :)

Thanks for checking it out!
