Go framework for production APIs

Performance-first Go web framework with production batteries.

elgon stays close to net/http but ships with Spring Boot-like readiness: health, metrics, config, auth, and OpenAPI.

Quick Start

app := elgon.New(elgon.Config{Addr: ":8080"})
app.Use(middleware.Recover(), middleware.RequestID())
app.GET("/health", func(c *elgon.Ctx) error {
  return c.JSON(200, map[string]string{"status": "ok"})
})
log.Fatal(app.Run())

Why elgon

Built for teams that care about latency and operability.

Performance-first core

A low-overhead router and middleware pipeline tuned for stable latency under load.

Production readiness

Health, metrics, secure defaults, and config validation ship as first-party modules.

Modular architecture

Adopt auth, OpenAPI, jobs, and migrations independently as your system evolves.

Testability

Composable interfaces and predictable request flow make handlers and services easy to test.

Feature set

Everything needed to ship and run APIs in production.

Core HTTP & Routing

Middleware

Errors

Validation & Binding

Auth

Observability

Config

DB + Migrations

Jobs

OpenAPI

CLI

Testing

Security Defaults

Benchmarks Module

Benchmarks

Benchmarks are a first-class module, not a side note.

Keep regression checks in your CI and compare route latency, allocations, and throughput over time.

Allocations / op

3 allocs

Router ns / op

350 ns

Throughput

1.2M req/min
