Fiber Observability with TraceKit
Fiber is the fastest Go framework -- but fasthttp's zero-allocation design makes debugging harder, not easier. Connection pool reuse hides request context, stack traces become opaque, and standard net/http instrumentation does not work. TraceKit bridges the fasthttp gap.
Fiber observability challenges
Common problems that Fiber developers face in production -- and how TraceKit solves them.
Zero-Allocation Routing Opacity
Fiber uses fasthttp instead of net/http, and its zero-allocation design reuses request and response objects from a pool. This makes stack traces misleading -- the request context you see in a panic may belong to a different request. TraceKit assigns unique trace IDs that survive pool reuse so every request is individually trackable.
fasthttp Instrumentation Gap
Most Go observability tools assume net/http. Fiber's fasthttp foundation means standard OpenTelemetry middleware does not work out of the box -- you need Fiber-specific instrumentation. TraceKit's Go SDK detects fasthttp and instruments Fiber's request lifecycle correctly.
Connection Pool Context Confusion
fasthttp reuses connections and request objects aggressively. When tracing is not pool-aware, spans can be attributed to the wrong request or carry stale context from a previous connection. TraceKit ensures clean context boundaries per request, even with fasthttp's pooling.
Get started in minutes
Add OpenTelemetry instrumentation to your Fiber app with a few lines of code.
import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/contrib/otelfiber/v2"
)
func main() {
app := fiber.New()
app.Use(otelfiber.Middleware())
// Your routes here
app.Listen(":3000")

What you get with TraceKit
Distributed Tracing
Trace requests through Fiber's fasthttp router, middleware chain, and downstream services. Full visibility into your high-performance Go application.
Live Code Monitoring
Set breakpoints in your Fiber handlers. Inspect fasthttp request context, middleware state, and response data in production without redeploying.
Simple Pricing
$29/month flat for your entire Fiber application. No per-connection fees, no per-request charges -- one price even at fasthttp throughput levels.
