You know the drill.

You need to see what a variable was at the exact moment something broke. So you:

1 Add a log statement
2 Push to Git
3 Wait 15 minutes for CI/CD
4 Cross your fingers it reproduces
5 Realize you logged the wrong thing
6 Repeat

Hours wasted. Customer still waiting. And you're thinking: "There has to be a better way."

Maybe you've looked at Datadog or New Relic. $500+/month. Enterprise sales calls. Dashboards built for teams of 50, not teams of 1.

Here's what happened to Alex.

Alex runs a subscription SaaS. Solo founder, Node.js stack, just started getting real customers.

The logs show the Stripe webhook hit the server. Status 200. But the subscription didn't activate. For some customers it works. For this one, it doesn't.

Can't reproduce it locally. Stripe's test webhooks work fine. The bug only happens in production, with real data, at random.
"

I spent two days adding logs, redeploying, waiting. Every time I thought I had it, I'd realize I needed to log something else. I was losing subscriptions.

Then they tried something different.

🎯

Instead of adding another log and redeploying, Alex added a capture point using the TraceKit SDK — one line of code at the suspicious webhook handler. From the dashboard, they enabled capturing and waited.

The next time a webhook failed, the SDK automatically captured the exact request payload, headers, and variable state at that moment. Alex inspected everything from the dashboard — no redeploy needed.

Root Cause Found

A race condition with an async database write. The log statement ran before the failure happened — that's why it never showed anything useful.

Time to find the bug: 10 minutes

Fixed in one deploy. No more lost subscriptions.

What made it possible?

TraceKit

Debug production without redeploying.

Add capture points with our SDK. Control them from the dashboard. Inspect variable state at any moment. See the full journey of every request. No redeploy to debug. No guessing.

🎯

Live Production Breakpoints

Set capture points in your code via our SDK. When issues occur, inspect variables, check state, and trace the exact path - all without stopping your app or deploying new code. Control everything from your dashboard.

Request Lifecycle Replay

Replay any request as a sequence diagram. See exactly what happened: which services were called, in what order, how long each took, and where it failed. Like a DVR for your distributed system.
