AndroidLibXrayLite
Lightweight Android library that bundles the Xray networking core
AndroidLibXrayLite is a lightweight Android library that bundles the Xray networking core as an embeddable component for apps. Its purpose is to provide a minimal, size-optimized build of the native core with a clear Java/Kotlin interface to start, stop, and configure network tunnels. By exposing the core as an AAR with per-ABI artifacts, it keeps application footprints small while supporting common CPU architectures. The library abstracts process management and log streaming so host apps can control lifecycles and capture diagnostics. It’s particularly useful for developers who want to integrate secure, rule-based proxying into their own Android apps without re-implementing the native glue. With a focus on stability and easy updates, it shortens the path from concept to a working in-app networking stack. -

Vegeta
HTTP load testing tool and library. It's over 9000!
Vegeta is a versatile HTTP load testing tool built out of a need to drill HTTP services with a constant request rate. It can be used both as a command line utility and a library. You can install Vegeta using the Homebrew package manager on Mac OS X. Both the library and the CLI are versioned with SemVer v2.0.0. After v8.0.0, the two components are versioned separately to better isolate breaking changes to each. CLI releases are tagged with cli/vMAJOR.MINOR.PATCH and published on the Github releases page. As for the library, new versions are tagged with both lib/vMAJOR.MINOR.PATCH and vMAJOR.MINOR.PATCH. The latter tag is required for compatibility with go mod. The JSON format makes integration with programs that produce targets dynamically easier. Each target is one JSON object in its own line. The method and url fields are required. If present, the body field must be base64 encoded. The generated JSON Schema defines the format in detail. -

age
A simple, modern and secure encryption tool (and Go library)
age is a security-oriented tool and library by Filo Sottile. age is a simple, modern, secure encryption utility (and Go library) that emphasizes minimal configuration and strong defaults. It provides small explicit keys, no complex options, and is designed for UNIX-style composability; you can pipe into it, integrate it into scripts, etc. It supports a clearly defined format and promotes interoperability across implementations (there are Rust, TypeScript, etc). The project is well-suited for personal data encryption, backup use-cases, scripting encryption workflows, and embedding encryption in tools. Because of its design philosophy, it avoids the bloat of many older encryption utilities while maintaining strong cryptographic hygiene. It’s especially useful for developers or system administrators who want to adopt encryption without learning a multitude of options. -

Go Container Registry
Go library and CLIs for working with container registries
go-containerregistry is a Go library (with companion tools) for interacting with container images and registries using OCI/Docker formats. It provides primitives to read, write, mutate, sign, and copy images and indexes across registries without shelling out to Docker. High-level utilities like crane and gcrane offer convenient CLIs for everyday tasks—listing tags, copying images between registries, flattening, creating tarballs, and more. The library handles authentication via a pluggable keychain system that understands Docker config files, credential helpers, and environment credentials. It understands multiple on-disk layouts (tarball, OCI layout, remote) and lets you transform images in memory by adding or rebasing layers, adjusting config, and annotating manifests. Because everything is regular Go code, it’s straightforward to embed in CI/CD systems, policy engines, and bespoke supply-chain tooling. -

go-chart
go chart is a basic charting library in go
Package chart is a very simple golang native charting library that supports time-series and continuous line charts. Master should now be on the v3.x codebase, which overhauls the api significantly. Per usual, see examples for more information. Actual chart configurations and examples can be found in the ./examples/ directory. They are simple CLI programs that write to output.png (they are also updated with go generate. Everything on the chart.Chart object has defaults that can be overridden. Whenever a developer sets a property on the chart object, it is to be assumed that value will be used instead of the default. The best way to see the api in action is to look at the examples in the ./_examples/ directory. I wanted to make a charting library that used only native golang, that could be stood up on a server (i.e. it had built-in fonts). The goal with the API itself is to have the "zero value be useful", and to require the user to not code more than they absolutely needed. -

lo
A Lodash-style Go library based on Go 1.18+ Generics
Samber/lo is a Lodash-style Go library based on Go 1.18+ Generics. This project started as an experiment with the new generics implementation. It may look like Lodash in some aspects. I used to code with the fantastic "go-funk" package, but "go-funk" uses reflection and therefore is not typesafe. As expected, benchmarks demonstrate that generics are much faster than implementations based on the "reflect" package. Benchmarks also show similar performance gains compared to pure for loops. In the future, 5 to 10 helpers will overlap with those coming into the Go standard library (under package names slices and maps). I feel this library is legitimate and offers many more valuable abstractions. -

GoDotEnv
A Go port of Ruby's dotenv library
A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file). Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables. But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped. It can be used as a library (for loading in env for your own daemons etc) or as a bin command. There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows. Existing envs take precedence of envs that are loaded later. -

go-github
Go library for accessing the GitHub API
go-github is a Go client library for accessing the GitHub API v3. Currently, go-github requires Go version 1.13 or greater. go-github tracks Go's version support policy. We do our best not to break older versions of Go if we don't have to, but due to tooling constraints, we don't always test older versions. If you're interested in using the GraphQL API v4, the recommended library is shurcooL/githubv4. go-github is compatible with modern Go releases in module mode. Resolve and add the package to the current development module, along with its dependencies. Alternatively the same can be achieved if you use import in a package. Construct a new GitHub client, then use the various services on the client to access different parts of the GitHub API. Some API methods have optional parameters that can be passed. Using the context package, one can easily pass cancelation signals and deadlines to various services of the client for handling a request. -

Uber Go Style Guide
The Uber Go Style Guide
This repository holds the Uber Go Style Guide, which documents patterns and conventions used in Go code at Uber. Styles are the conventions that govern our code. The term style is a bit of a misnomer, since these conventions cover far more than just source file formatting—gofmt handles that for us. The goal of this guide is to manage this complexity by describing in detail the Dos and Don'ts of writing Go code at Uber. These rules exist to keep the code base manageable while still allowing engineers to use Go language features productively. This guide was originally created by Prashant Varanasi and Simon Newton as a way to bring some colleagues up to speed with using Go. Over the years it has been amended based on feedback from others. This documents idiomatic conventions in Go code that we follow at Uber. A lot of these are general guidelines for Go, while others extend upon external resources. -

retry
Simple golang library for retry mechanism
Simple library for retry mechanism. Context allow to set context of retry default are Background context. Return the direct last error that came from the retried function default is false (return wrapped errors with everything) WithTimer provides a way to swap out timer module implementations. This primarily is useful for mocking/testing, where you may not want to explicitly wait for a set duration for retries. DelayTypeFunc is called to return the next delay to wait after the retriable function fails on err after n attempts. FixedDelay is a DelayType that keeps delay the same through all iterations. DelayTypeFunc accepts a new parameter err - this breaking change affects only your custom Delay Functions. RetryIf controls whether a retry should be attempted after an error (assuming there are any retry attempts remaining). -

Cobra
A Commander for modern Go CLI interactions
Cobra is a library for creating powerful modern CLI applications, and at the same time a program to generate applications and command files. It provides a simple interface for creating powerful CLI interfaces, and will also generate application scaffolding so you can quickly develop your Cobra-based application. This scaffolding includes easy subcommand-based CLIs, fully POSIX-compliant flags, global, local and cascading flags, among many others. The structure of Cobra is based on commands, flags and arguments. The commands represent actions, the central point of the application; flags modify the behavior of commands; while arguments are things. With these easy-to-use concepts, users will natively understand how to use the application. -

Go Katas
A collection of daily coding challenges
Go Katas is a curated collection of practice exercises and coding challenges specifically crafted to improve proficiency in Go, including idiomatic patterns, language fundamentals, and algorithm design. It mirrors the kata practice tradition from martial arts—repetitive, thoughtful practice where each exercise reinforces technique, discipline, and problem-solving approach. Each kata prompt focuses on a precise aspect of Go, such as concurrency patterns, memory management, interfaces, error handling, or performance optimization, giving learners structured practice opportunities that go beyond syntax. Implementations can be tested locally, graded automatically with included test suites, and iterated on so that learners get rapid feedback and measurable progress. Because Go is widely used for backend services, cloud tooling, and systems programming, this repository helps participants build confidence in writing reliable, idiomatic, and maintainable code in real environments. -

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. -

env
A simple and zero-dependencies library to parse environment variables
Parse environment variables to structs in Go. In Go, it’s dead simple to get the value from an environment variable. If you have a type that is not supported out of the box by the lib, you are able to use (or define) and pass custom parsers (and their associated reflect.Type) to the env.ParseWithFuncs() function. Env supports by default anything that implements the TextUnmarshaler interface. That includes things like time.Time for example. The upside is that depending on the format you need, you don't need to change anything. The downside is that if you do need time in another format, you'll need to create your own type. By default, slice types will split the environment value on ,; you can change this behavior by setting the envSeparator tag. If you set the envExpand tag, environment variables (either in ${var} or $var format) in the string will be replaced according with the actual value of the variable.
