fasthttp vs Gin
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A Go HTTP library tuned for speed, aimed at high-volume servers and clients.
Open source · MIT
A fast Go web framework for building HTTP APIs and web services with a simple routing API.
The short answer
Choose fasthttp if you need…
- Go developers whose server must handle thousands of small-to-medium requests per second
- Teams that have measured net/http and found HTTP handling to be a real bottleneck
- Projects with very high numbers of keep-alive connections, as in the VertaMedia example in the README
- Developers comfortable adapting code to a non-standard API
Choose Gin if you need…
- Go developers building REST APIs
- Teams writing microservices in Go
- Developers who want a Martini-like API with a faster router
- Projects where request throughput matters

What each one is
fasthttp
fasthttp is an HTTP server and client package for the Go programming language, built to be faster than Go's standard net/http package. It reduces memory allocations in its hot paths, which the README says gives higher throughput. The README itself warns that it is designed for specific high-performance cases and that net/http is easier to use and suits most projects.
Gin
Gin is an HTTP web framework written in Go. It gives you a simple way to define routes, handle requests, return JSON or HTML, and use middleware such as logging and panic recovery. The project says it is much faster than many other Go frameworks, citing a GitHub API routing benchmark included in its README.

fasthttp
- Go developers whose server must handle thousands of small-to-medium requests per second
- Teams that have measured net/http and found HTTP handling to be a real bottleneck

Gin
- Go developers building REST APIs
- Teams writing microservices in Go
- Developers who want a Martini-like API with a faster router
- Projects where request throughput matters
Strengths
fasthttp
- The README includes benchmark tables comparing it with net/http, with zero allocations reported for its server GET benchmarks
- Actively maintained, with a v1.77.0 release and a recent push date
- Released under the permissive MIT license
Gin
- Designed for speed, with benchmarks in the README showing low allocation routing
- Simple, Martini-like routing API with a short getting-started example
- Has a large ecosystem of middleware and documentation in several languages
Not ideal for
fasthttp
- Most typical Go web services, because the README says net/http is much better for most cases and easier to use
- Projects that need broad compatibility with net/http handlers and middleware, since the README notes net/http can handle more cases
- Beginners learning Go web development, since the API differs from the standard library
Gin
- Non-programmers, since it is a Go library and requires writing code
- Teams not using Go, because it only works in that language
- Projects needing a full batteries-included framework with built-in ORM or admin panel, as the README describes a focused routing and middleware framework
Trade-offs
fasthttp
- The README explicitly says it is not for most use cases and net/http is usually the better choice
- Benchmark figures come from a single Intel Xeon test setup and may not match your workload
- The latest release has no prebuilt binaries, since it is a library rather than an application
Gin
- Requires Go 1.26 or above, which may be newer than some existing setups
- Performance claims rely on the project's own benchmark, so real results depend on your workload
- Latest release has no prebuilt binaries, since it is used as a library
