Gin vs Echo vs Fiber for a Go API

Gin, Echo, and Fiber all give Go a router, middleware, and helpers for binding and rendering JSON. The decision rarely comes down to routing syntax. It comes down to which HTTP engine sits underneath, what that means for the libraries you can reuse, and which major version you would be starting on.

HTTP foundation

Gin and Echo build on Go's standard net/http. Gin's Engine has a ServeHTTP method that "conforms to the http.Handler interface," and Run starts a standard http.Server (source). Echo's ServeHTTP likewise "implements http.Handler interface" (v4 source). Both therefore inherit the standard library's connection model: http.Server.Serve creates a new service goroutine for each connection.

Fiber is different. It describes itself as an Express-inspired web framework built on top of Fasthttp, and the fasthttp README states plainly that its API "is incompatible with net/http." Fiber v2's README says "Fiber is not compatible with net/http interfaces" and names gqlgen and go-swagger as examples of what that excludes (Fiber v2 README). Fiber v3's README says its router accepts existing net/http handlers directly and points to the adaptor middleware for converting handlers and middleware in both directions.

Request context rules

Fiber reuses request objects to avoid allocations. Its documentation warns that values returned from fiber.Ctx "are not immutable by default and will be reused across requests": use them only inside the handler, copy anything you need to keep, or enable the Immutable setting. Fasthttp itself forbids holding references to the request context after the handler returns.

Gin and Echo hand you a context wrapped around the standard *http.Request. Both also take that context from a pool and return it when the handler finishes, so a goroutine that outlives the request must not keep the framework context. Gin's documentation says to pass a copy made with c.Copy() to goroutines; with Echo, read what you need from the context before starting the goroutine.

Middleware and library fit

Any library that ships a net/http handler or middleware (auth servers, metrics exporters, OpenAPI tooling) fits Gin and Echo with a thin wrapper: Gin has gin.WrapH and gin.WrapF, and Echo has echo.WrapHandler and echo.WrapMiddleware. With Fiber, the same library goes through an adaptor, so check every net/http dependency you plan to use.

Each framework also has its own middleware set. Gin's documentation lists middleware support, panic recovery, JSON validation, route grouping, error management, and built-in JSON, XML, and HTML rendering. Fiber ships built-in middleware and officially maintained contrib packages. Echo describes itself as a minimalist Go web framework.

Major-version status

This is the criterion most likely to affect a new project, and it is where the generated code needs a decision from you:

• Gin v1.12.0 was released on 2026-02-28 (releases).
• Echo v5.0.0 was released on 2026-01-18. Its release notes describe major breaking changes, including Context becoming a struct, so handlers take *echo.Context, and state that v4 is supported with security updates and bug fixes until 2026-12-31.
• Fiber v3.0.0 was released on 2026-02-02, with a migration tool (fiber migrate --to v3) linked from the release notes. The v2 line still receives patch releases; v2.52.15 was released on 2026-08-12.

What Better Fullstack generates

The three commands below differ only in --go-web-framework:

bun create better-fullstack@latest my-api \
  --ecosystem go \
  --go-web-framework gin \
  --database postgres \
  --go-orm gorm \
  --go-logging zap \
  --auth none

bun create better-fullstack@latest my-api \
  --ecosystem go \
  --go-web-framework echo \
  --database postgres \
  --go-orm gorm \
  --go-logging zap \
  --auth none

bun create better-fullstack@latest my-api \
  --ecosystem go \
  --go-web-framework fiber \
  --database postgres \
  --go-orm gorm \
  --go-logging zap \
  --auth none

Add --dry-run to preview any of them without writing files. All three share the same layout and data layer: cmd/server/main.go, plus internal/database, internal/models, and internal/handlers. GORM auto-migrates User and Post models at startup, and the handlers expose list, get, create, update, and delete routes under /api/users and /api/posts. godotenv loads .env, and zap handles logging. The framework-specific code sits in main.go and the handler signatures:

The generated projects have limits to plan for:

• Echo and Fiber are generated on their previous major versions, v4 and v2. Moving to Echo v5 or Fiber v3 is a code migration, not a version bump, and Echo v4's announced support window ends on 2026-12-31.
• When DATABASE_URL is empty, the database package opens a local SQLite file, app.db. It uses the PostgreSQL driver only when the URL starts with postgres. .env.example contains a PostgreSQL URL to copy into .env.
• Handlers reach the database through a package-level *gorm.DB, and no _test.go files are generated.

If you leave out --auth none, the Go default adds go-better-auth, which is mounted as a standard net/http handler: Gin wraps it with gin.WrapH, Echo with echo.WrapHandler, and Fiber with adaptor.HTTPHandler from gofiber/adaptor. That is the net/http difference from above, showing up in generated code.

These are generated projects, not runtime-verified deployments. Run go build ./... and exercise the routes against your database before committing to one.
