Express Observability with TraceKit
Express middleware is simple until you have 15 layers and a request takes 3 seconds. TraceKit traces every middleware hop, maintains context across async/await boundaries, and helps you find memory leaks before your users do.
Why Express Needs Better Observability
Common debugging challenges that traditional monitoring tools miss.
Middleware Stack Debugging
Express apps accumulate middleware layers -- body parsers, auth, CORS, rate limiting, logging. When latency spikes, which layer is responsible? TraceKit instruments every middleware automatically so you can pinpoint the slow one.
Async/Await Trace Continuity
Node.js async execution makes traces fragile. Context gets lost across await boundaries, setTimeout callbacks, and event emitters. TraceKit's SDK maintains trace context through the entire async chain.
Memory Leak Detection
Node.js memory leaks are notoriously hard to diagnose in production. TraceKit correlates memory growth with specific request patterns and traces, so you can identify which endpoints are leaking.
Get Started in Minutes
Add TraceKit to your Express project with a few lines of code.
const { NodeSDK } = require('@opentelemetry/sdk-node');
const { getNodeAutoInstrumentations } = require('@opentelemetry/auto-instrumentations-node');
const sdk = new NodeSDK({
instrumentations: [getNodeAutoInstrumentations()],
serviceName: 'my-express-service',
});
sdk.start();What You Get with TraceKit
Everything you need to monitor Express in production.
Distributed Tracing
Trace requests across Express middleware, external API calls, and database queries. Full visibility into your async Node.js request lifecycle.
Live Code Monitoring
Set breakpoints in your Express route handlers. Inspect request objects, middleware state, and response data in production without redeploying.
Simple Pricing
$29/month flat for your entire Node.js application. No per-process fees, no per-request charges -- predictable cost as your Express app scales.
