Go HTTP Routers and Toolkits

Chi is a lightweight, idiomatic router and middleware framework for building web services in Go. It is designed to integrate directly with the standard library, providing a set of utilities for managing HTTP request routing, context propagation, and modular service composition. The project distinguishes itself through a radix-tree-based routing system that supports recursive nesting, allowing developers to mount independent sub-routers onto specific path prefixes. This hierarchical structure enables the creation of organized, modular applications where request handlers are grouped and managed

This project is a request router and web framework for the Go programming language. It provides a toolkit for matching incoming HTTP network requests to specific handler functions by evaluating criteria such as URL paths, request methods, headers, and hostnames. The framework distinguishes itself through its flexible matching capabilities, which include support for regular expressions and dynamic variable extraction from URL segments. It allows developers to organize routes into logical hierarchies, share common path prefixes, and maintain a central registry of named routes to facilitate prog

Echo is a high-performance, lightweight web framework for Go designed for building scalable RESTful APIs and web services. It provides a centralized environment for mapping network requests to handler functions, utilizing a fast radix-tree routing engine to ensure efficient request dispatching. The framework is built around a modular, middleware-centric pipeline that allows developers to execute reusable logic for cross-cutting concerns like authentication, logging, and security across the entire application. What distinguishes Echo is its focus on developer productivity through structured da

Gofr is a comprehensive framework for building production-ready microservices in Go. It provides a unified toolkit for developing RESTful APIs and gRPC services, offering built-in support for observability, database management, and distributed system communication. The framework distinguishes itself through its focus on developer productivity and system resilience. It automates common backend tasks such as CRUD handler generation, schema-driven code creation, and database migration orchestration, while preventing race conditions in clustered environments. To maintain stability, it includes in

Iris is a high-performance web framework and API toolkit for the Go programming language. It provides the infrastructure necessary to build HTTP/2 web applications, REST APIs, and MVC-based websites. The project distinguishes itself through a flexible architectural model that supports multiple isolated application instances within a single process and allows for binary-embedded asset loading to eliminate external filesystem dependencies. It features dynamic router hot-reloading and a pluggable view engine for rendering dynamic HTML content. The framework covers a broad range of capabilities,

Gin is a web framework designed for building high-performance web services and APIs. It functions as a middleware-oriented engine that processes incoming HTTP requests through a sequential chain of handlers, allowing for the modular management of cross-cutting concerns such as authentication and logging. The framework utilizes a radix tree data structure to perform request routing, ensuring high-speed path matching with minimal memory overhead. It distinguishes itself by employing a zero-reflection dispatch mechanism that invokes handler functions through static type assertions, avoiding the

httprouter is a high-performance HTTP request router for Go that maps incoming network requests to specific handler functions using a radix tree. It functions as a request dispatcher and path parameter parser, organizing URL paths in a tree structure to ensure efficient lookups. The router specializes in capturing dynamic segments and catch-all wildcards from URL paths to pass directly into request handlers. It implements method-specific routing and automatically manages responses for unsupported HTTP methods. The library covers broader capabilities including request normalization through tr

Fiber is a high-performance web framework designed for building scalable HTTP services with minimal memory overhead. It provides a comprehensive runtime environment for managing the full request lifecycle, utilizing an optimized radix tree for high-speed route matching and an object pooling system to reduce garbage collection pressure during traffic processing. The framework distinguishes itself through its multi-process architecture, which supports prefork socket reuse to distribute incoming traffic across all available CPU cores. It offers a modular approach to application development, feat

Huma is an OpenAPI REST framework for Go designed for building HTTP services with automatic OpenAPI 3.1 specification generation and JSON Schema validation. It serves as a toolkit for developing REST and RPC APIs with typed inputs and outputs, deriving interactive documentation directly from the source code. The framework distinguishes itself by automating the synchronization between implementation and documentation. It uses a content-negotiation engine to manage multiple serialization formats via client headers and employs a JSON Schema input validator to automatically verify request paramet

Fx is a dependency injection framework and application lifecycle manager for Go. It functions as a component model container that automates the instantiation and connection of components by analyzing constructor parameters and return values to resolve complex dependency graphs. The framework distinguishes itself through module-based component bundling, which encapsulates related constructors into reusable units to manage visibility and logic. It provides advanced resolution capabilities, including mapping concrete types to interfaces for decoupling, resolving dependency ambiguities via unique
