Hey Tal, we focus on the frontend and don't officially support node. That said, or community has built a node agent that several folks use. It works, but it's not our focus.

Hey Tal, I'm Todd from TrackJS. Despite my obvious bias (trackjs is the best), I'll attempt to share my overall thoughts. Some of the services are general purpose error trackers (sentry and BugSnag) and bring together data from multiple platforms, while the rest (TrackJS) focus on JavaScript. The former are better at "whole system visibility", while the latter give you better information and and tools on the JavaScript space. Your first decision is which kind of tool you need. Beyond that, each tool has a different balance of tracking data and visual priorities. TrackJS focuses on highly compatible agents that provide context about what happened before the error, and visually simple and easy to understand. The contrast to this is that we lack some more powerful custom reporting capabilities that we feel are difficult to understand. The best way to decide is really to just try them out. TrackJS is just a drop-in install and totally free for 30 days. I imagine the others are similar. Give it a try, ask some questions, and see how it feels for you and your team. Let me know if I can help. Todd at trackjs.com. Best of luck on your project! Todd.
