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.
Why Fiber Needs Better Observability
Common debugging challenges that traditional monitoring tools miss.
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 TraceKit to your Fiber project 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
Everything you need to monitor Fiber in production.
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.
