Do any of these sound familiar?

It's 11pm. A user messages you: "Your app has been broken for the last hour." RateLimitErrorHundreds of them. The API started throttling at 10:03pm your users have been staring at a loading spinner for 57 minutes. You had no idea.

Or maybe it wasn't an error. Maybe it was the bill. You open your OpenAI dashboard on a Tuesday and see a number that doesn't match your mental model. Something changed last week a new feature, a longer prompt, a loop that ran one too many times. You have no trace. You change things and hope the next bill is lower.

Or it's latency. Users say the app "feels slow." Is it the model? The prompt length? The server? A tool call that timed out? You're guessing. That's not engineering that's luck.

The problem isn't that your AI app breaks. The problem is that you're the last to know.

How it works

2 lines of code. Full visibility.

1Step 1

Install the SDK

One package. Works with Node.js, Python, and PHP. No agents, no sidecars, no YAML.

2Step 2

Add one line per LLM call

Wrap your existing call with kora.track(). Your code doesn't change just one line after the response.

3Step 3

Get alerted before your users do

Errors, latency spikes, and cost anomalies hit your WhatsApp or email in real time. No dashboard to open.
