Console Fatigue is Real.

You didn't become a developer to parse JSON with your eyes.

The Endless Scroll

Your app spits out 500 lines of JSON per second. You're hunting for one userId. Your eyes glaze over.

"2,847 lines. One error. Good luck."

The Copy-Paste Ritual

Copy log line. Open browser. Paste into JSON formatter. Realize you grabbed the wrong line. Repeat.

"Your clipboard knows too much."

Cloud Console Hell

You just want to see what happened 30 seconds ago. GCP Logs Explorer takes 8 seconds to load. Then another 4 to filter.

"Waiting for AWS to show you your own logs."

Logs are supposed to help you debug. Instead, they've become the thing you need to debug around.

From Chaos to Clarity in 3 Steps.

Get started in under a minute. No account required. Everything configurable through the UI.
