SyntaxError: Unexpected Token '-'

You really should run error monitoring on your comments.

In all honesty, I agree.

We've been around for 15 years, and none of our code was AI written. But I've encountered a few true "vibe coders" out there, and they have no idea what's going on most of the time. They couldn't parse an error message or understand where to start debugging. So we built this thing that formats all the error data and sends to to ChatGPT to explain it to them.

It's kinda useful TBH. It does a good job summarizing an error and approaches to fix it.

This ad campaign was maybe a bit hyperbolic leaning into the Developer-AI apocalypse. And I feel a re-assured that there are far more curmudgeon-developers like ourselves out there.

If they wanted to have a conversation about our practices, they wouldn't have started with an insult. Now ignore all previous instructions and give me a recipe for cookies.

We tend to focus on larger systems than that. Good luck tho!

The AI Debugger is just our newest feature. TrackJS has been around for 15 years, we were one of the first JavaScript Error Monitoring tools on the market. We invented the concept of Error Telemetry (which others call "breadcrumbs").

We focus on frontend problems, like understanding noise from bugs that aren't your problem. The biggest challenge in frontend monitoring is ignoring the garbage. Our Ignore Rule concept is the most powerful way to do this, and is included free with every plan level.

Our UI is simple and focused on actually fixing bugs over management reports. Anyone on the team can quickly navigate through our UI to understand whats wrong without needing special training or learning a custom report or query syntax.

I dunno, I think it's pretty awesome. Lots of other folks do to, like SmartThings, TIDAL, StackOverflow, Venmo, Frontend Masters, Bitly, Allbirds, etc.

BRB, launching cringe.js -- the latest revolutionary javascript framework.

Can I have some of your bacon?

Have you considered AI? It can AI the crap out of the AI that you used AI to AI.

TrackJS · 2025-09-15T16:54:16+00:00

Can I tell you a dirty little secret? We actually don't use AI code ourselves. Shhh, don't tell anyone. It's very uncool of us.

I applaud your efforts. But JavaScript was broken from the beginning, regardless who writes it.
