Frameworks

Go’s standard library is unusually capable, so frameworks tend to be thin. The community generally prefers small, composable packages over monolithic frameworks.

HTTP / Web

The standard net/http is good enough for production. Common upgrades add routing, middleware, and validation.

• chi , idiomatic router on net/http.

• gorilla/mux , mature router; the project re-emerged in 2023.

• echo , ergonomic, minimal.

• gin , popular for its API and performance reputation.

• fiber , Express-like, fasthttp-based.

• huma , OpenAPI-first APIs.

• Encore , opinionated framework with built-in infra.

RPC / Service

• grpc-go , official gRPC.

• connect-go , gRPC-compatible plus HTTP/JSON.

• Twirp , simpler RPC over HTTP/Protobuf.

• go-kit , toolkit for microservices.

• Kratos , microservice framework.

ORM / Data Access

• database/sql , standard library; the foundation everything builds on.

• pgx , Postgres driver and toolkit; the de-facto choice.

• sqlc , generates type-safe Go from SQL queries.

• sqlx , thin extensions to database/sql.

• ent , Facebook’s entity framework with codegen.

• gorm , traditional ORM.

• bun , modern, query-first.

• goqu , SQL builder.

CLI

• cobra , the most-used CLI framework (used by kubectl, docker, hugo).

• urfave/cli , alternative.

• kong , struct-tag-driven.

• cli-go (charm), Bubble Tea for TUIs.

Configuration

• viper , many sources (env, files, flags, remote).

• koanf , simpler alternative to viper.

• envconfig / caarlos0/env, env vars to structs.

Background Work / Queues

• Asynq , Redis-backed job queue.

• River , Postgres-backed jobs.

• Machinery, distributed task queue.

• Watermill , event-driven applications.

Testing

• testing , standard library.

• testify , assertions, mocks.

• gomock , mock generation.

• Ginkgo + Gomega, BDD-style.

• httptest , standard library; HTTP integration tests.

Observability

• OpenTelemetry-go, the standard.

• slog , structured logging in stdlib (Go 1.21+).

• zap, zerolog, fast loggers.

• prometheus/client_golang, metrics.

WebAssembly / Edge

• wasmtime-go, wazero, WASM runtimes embeddable in Go.

Why “Boring” Wins in Go

The Go culture is suspicious of magic and frameworks. The most-used “framework” in production is net/http + a router + database/sql + a logger. That stack is hard to beat for clarity and longevity.
