Interactsh
An OOB interaction gathering server and client library
Interactsh is an open-source tool for detecting out-of-band interactions. It is a tool designed to detect vulnerabilities that cause external interactions. Interactsh Cli client requires go1.17+ to install successfully. interactsh-client with -sf, -session-file flag can be used store/read the current session information from user defined file which is useful to resume the same session to poll the interactions even after the client gets stopped or closed. Running the interactsh-client in verbose mode (v) to see the whole request and response, along with an output file to analyze afterwards. Using the server flag, interactsh-client can be configured to connect with a self-hosted Interactsh server, this flag accepts single or multiple server separated by comma. Default servers are subject to change/rotate/down at any time, thus we recommend using a self-hosted interactsh server if you are experiencing issues with the default server. -

Kafka-Pixy
gRPC/REST proxy for Kafka
Kafka-Pixy is a dual API (gRPC and REST) proxy for Kafka with automatic consumer group control. It is designed to hide the complexity of the Kafka client protocol and provide a stupid simple API that is trivial to implement in any language. Kafka-Pixy is tested against Kafka versions 1.1.1 and 2.3.0, but is likely to work with any version starting from 0.8.2.2. It uses the Kafka Offset Commit/Fetch API to keep track of consumer offsets. However Group Membership API is not yet implemented, therefore it needs to talk to Zookeeper directly to manage consumer group membership. Kafka-Pixy does not support wildcard subscriptions and therefore cannot coexist in a consumer group with clients using them. It should be possible to use other clients in the same consumer group as kafka-pixy instance if they subscribe to topics by their full names, but that has never been tested so do that at your own risk. -

Typhon
A wrapper around Go's net/http to provide safety and convenience
Typhon is a wrapper around Go's net/http library that we use at Monzo to build RPC servers and clients in our microservices platform. A wrapper around Go's net/http to provide safety and convenience. At Monzo, Typhon forms the basis of most clients and servers in our microservices platform. Forgetting to body.Close() in a client when the body has been dealt with is a common source of resource leaks in Go programs in our experience. Typhon ensures that – unless you're doing something really weird with the body – it will be closed automatically. Marshalling and unmarshalling request bodies to structs is such a common operation that our Request and Response objects support them directly. If the operations fail, the errors are propagated automatically since that's nearly always what a server will want. -

chi
Lightweight, idiomatic & composable router to build Go HTTP services
chi is a lightweight, open source composable router for building Go HTTP services. It also helps in writing large REST API services, keeping them maintainable as the project evolves. Having been built on the latest context package, it can easily handle signaling, cancelation and request-scoped values across a handler chain. chi was built with the sole focus of providing an elegant and comfortable design for writing REST API servers. Its design chiefly considers project structure, maintainability, standard http handlers (stdlib-only), developer productivity, and deconstructing a large system into many small parts. It is very lightweight and fast (according to benchmarks), yet is still able to include several useful subpackages (middleware, render and docgen). -

goflyway
An encrypted HTTP server
master is the active development branch and contains v2 code, for the stable v1 release (though it was once called v2.0), please refer to v1.0 branch. goflyway v2 is a special tool to forward local ports to a remote server securely, just like ssh -L. goflyway uses pure HTTP POST requests to relay TCP connections. There is no CONNECT involved nor needed because goflyway is designed mainly for those people who are behind a CONNECT-less HTTP proxy or want to accelerate connections through static CDNs. However pure HTTP requesting is definitely a waste of bandwidth if you already have a better network environment, so use -w to turn on WebSocket relay, or -K to turn on KCP relay if possible. In HTTP mode when the server received some data it can't just send them to the client directly because HTTP is not bi-directional, instead, the server must wait until the client requests them, which means these data will be stored in memory for some time. -

gorilla/mux
HTTP router and URL matcher for building Go web servers
Package gorilla/mux implements a request router and dispatcher for matching incoming requests to their respective handler. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are that it implements the http.Handler interface so it is compatible with the standard http.ServeMux, requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers, URL hosts, paths and query values can have variables with an optional regular expression. Also, registered URLs can be built, or "reversed", which helps maintaining references to resources, Routes can be used as subrouters: nested routes are only tested if the parent route matches. And many more features. -

plow
A high-performance HTTP benchmarking tool
Plow is an HTTP(S) benchmarking tool, written in Golang. It uses excellent fast HTTP instead of Go's default net/http due to its lightning-fast performance. Plow runs at specified connections (option -c) concurrently and real-time records summary statistics, histogram of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration( option -d), for a fixed number of requests(option -n), or until Ctrl-C is interrupted. The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by Prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking. -

COW
HTTP proxy to automatically identify blocked sites
HTTP proxy written in Go. COW can automatically identify blocked sites and use parent proxies to access. COW's design goal is automation. Ideally, users don't need to care about which websites are inaccessible, and they can directly connect to the website without slowing down the access speed due to the use of secondary agents. As an HTTP proxy, it can be provided to mobile devices; if deployed on a domestic server, it can be used as an APN proxy. Support HTTP, SOCKS5, shadowsocks and cow itself as a secondary proxy. Multiple secondary agents can be used to support simple load balancing. Automatically detect whether the website is blocked, and only use the secondary proxy for the blocked website. Automatically generate PACs containing directly connected websites, you can bypass COW when visiting these websites. Built-in common websites that can be directly connected , such as domestic social, video, bank, e-commerce and other websites (can be added manually). -

EGO
A simple and component-based microservice kit for go
EGO is a microservice-oriented governance framework implemented by golang, which integrates various engineering practices. Through the component-based design pattern, it is guaranteed that the business development can use various components in a unified way. For us engineers to improve component proficiency, we must first read a lot of open-source component documentation and code, and then insist on using it for a long time in order to form muscle memory and improve our speed of doing business. And the time and energy invested in all of this is enormous. To reduce this input cost and allow more developers to better use excellent open source components, EGO's approach is to standardize all open source components, encapsulate them, and unify various behaviors. -
23
FastHTTP
Fast HTTP package for Go
FastHTTP is the fastest and reliable HTTP implementation for Go. FastHTTP is tuned for high performance, with zero memory allocations in hot paths. In benchmarks, both FastHTTP server and client have shown to be up to 10 times faster than those of net/http. However, FastHTTP does not provide an API identical to net/http, but it is better to write FastHTTP request handlers by hand so as to make use of all its advantages. One of its key advantages is that unlike net/http it does not limit many optimization opportunities, such as reusing existing objects per request and avoiding unnecessary memory allocations. -
24
Go Safe Web
Secure-by-default HTTP servers in Go
go-safeweb is a security-focused HTTP framework for Go that bakes in secure defaults so common web vulnerabilities are harder to introduce. Instead of leaving headers and policies to ad-hoc middleware, it sets Content Security Policy, X-Frame-Options, and other protections by default, and centralizes template escaping rules. Request handling emphasizes principled APIs for parsing and validating input, reducing the risk of injection and deserialization bugs. The framework’s routing and response layers are designed to be explicit and auditable, making it clearer when unsafe behaviors are being opted into. It also offers utilities for CSRF protection, secure cookies, and safe resource embedding that work well with Go’s standard library. By turning security posture into a first-class concern, go-safeweb helps teams achieve defense-in-depth without scattering security logic across a codebase. -
25
Gzip Handler
Go middleware to gzip HTTP responses
This is a tiny Go package that wraps HTTP handlers to transparently gzip the response body, for clients which support it. Although it's usually simpler to leave that to a reverse proxy (like nginx or Varnish), this package is useful when that's undesirable. Call GzipHandler with any handler (an object which implements the http.Handler interface), and it'll return a new handler which gzips the response.
