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. -

Go QueryString
go-querystring is Go library for encoding structs into URL query
go-querystring is a lightweight Go library developed by Google for encoding Go structs into URL query strings. It simplifies the process of constructing URLs with typed parameters, offering a clean, type-safe approach to building query strings programmatically. The library’s query package exposes a single Values() function that converts struct fields (tagged with url tags) into properly encoded query parameters. It is particularly useful for APIs or HTTP clients that represent query parameters as structs—such as in the go-github client library. Each struct field can be annotated with a url:"name" tag to specify the query key. The encoder supports standard Go data types (strings, numbers, booleans, slices, etc.) and handles formatting and escaping automatically. -

Stash
An organizer for your videos, written in Go
Stash allows you to organize and view your own collection of adult video and image files. Think of it like a private Hub site for your personal porn collection. Every video file has its own scene. Scenes can be rated and tagged with performers, tags, movies and a studio. Bookmark your favorite parts of a scene with markers. Markers can be tagged and appear in the video scrubber when viewing a scene. Images can be rated and tagged with performers, tags and a studio. Galleries are collections of images. Galleries can be automatically created from zip files and folders containing image files. Preview and view all of your scenes and galleries from your web browser on your PC, tablet or phone. Stash directly streams videos to your web browser. Stash supports streaming of a large variety of formats and codecs to most web browsers. -

Casbin
An authorization library that supports access control models
An authorization library that supports access control models like ACL, RBAC, ABAC for Golang, Java, C/C++, Node.js, Javascript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter) and Elixir. In Casbin, an access control model is abstracted into a CONF file based on the PERM metamodel (Policy, Effect, Request, Matchers). So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. Besides memory and file, Casbin policy can be stored into lots of places. Currently, dozens of databases are supported, from MySQL, Postgres, Oracle to MongoDB, Redis, Cassandra, AWS S3. Check the full supported list at: adapters. Casbin is implemented in Golang, Java, PHP and Node.js. All implementations share the same API and behaviors. You can learn Casbin once and use it everywhere. In Casbin, the policy storage is implemented as an adapter(aka middleware for Casbin). -

Go gRPC Middleware
Golang gRPC Middlewares: interceptor chaining, auth, logging, retries
gRPC Go has support for "interceptors", i.e. middleware that is executed either on the gRPC Server before the request is passed onto the user's application logic, or on the gRPC client either around the user call. It is a perfect way to implement common patterns: auth, logging, tracing, metrics, validation, retries, rate limiting, and more, which can be great generic building blocks that make it easy to build multiple microservices. Especially for observability signals (logging, tracing, metrics) interceptors offer semi-auto-instrumentation that improves the consistency of your observability and allows great correlation techniques (e.g. exemplars and trace ID in logs). Demo-ed in examples. This repository offers ready-to-use middleware that implements gRPC interceptors with examples. In some cases, dedicated projects offer great interceptors, so this repository skips those, and we link them in the interceptors list. -

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. -

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. -

GoNB
GoNB, a Go Notebook Kernel for Jupyter
Go is a compiled language, but with very fast compilation, that allows one to use it in a REPL (Read-Eval-Print-Loop) fashion, by inserting a "Compile" step in the middle of the loop -- so it's a Read-Compile-Run-Print-Loop — while still feeling very interactive. GoNB leverages that compilation speed to implement a full-featured (at least it's getting there) Jupyter notebook kernel. As a side benefit it works with packages that use CGO — although it won't parse C code in the cells, so it can't be used as a C kernel. It already includes many goodies: cache between cell of results, contextual help and auto-complete (with gopls), compilation error context (by mousing over), bash command execution, images, html, etc. See the tutorial. It's been heavily used by the author (in developing GoMLX, a machine learning framework for Go), but should still be seen as experimental — if we hear success stories from others, we can change this. -

XLSX
Go (golang) library for reading and writing XLSX files
xlsx is a library to simplify reading and writing the XML format used by recent version of Microsoft Excel in Go programs. Version 3.0.0 introduces some more breaking changes in the API. All methods that can return an `xlsx.File` struct now accept zero, one or many `xlsx.FileOption` functions as their final arguments. These can be used to modify the behavior of the resultant struct, in particular they replace the `…WithRowLimit` variants of those methods with the result of calling `xlsx.RowLimit` and they add the ability to define a custom backing store for the spreadsheet data to be held in whilst processing. The full API docs can be viewed using go’s built in documentation tool. -

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. -

Distribution
The Docker toolset to pack, ship, store, and deliver content
Distribution is a repository that contains the Open Source Docker Registry implementation, which is for the storage and distribution of Docker and OCI images using the OCI Distribution Specification. The goal of this project is to provide a simple, secure yet professional-grade and scalable content distribution system that lets users store, package, manage and exchange content in a reliable and efficient way. It also allows users to hack or roll their own content atop healthy open source components and implement their own solutions. The repository has three main components: the registry, libraries for interacting with distribution components, and the documentation related to the registry. -

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. -

eBPF
ebpf-go is a pure-Go library to read, modify and load eBPF programs
Package ebpf is a toolkit for working with eBPF programs. eBPF programs are small snippets of code which are executed directly in a VM in the Linux kernel, which makes them very fast and flexible. Many Linux subsystems now accept eBPF programs. This makes it possible to implement highly application-specific logic inside the kernel, without having to modify the actual kernel itself. This package is designed for long-running processes which want to use eBPF to implement part of their application logic. It has no run-time dependencies outside of the library and the Linux kernel itself. eBPF code should be compiled ahead of time using clang, and shipped with your application as any other resource. Use the link subpackage to attach a loaded program to a hook in the kernel. Note that losing all references to Map and Program resources will cause their underlying file descriptors to be closed, potentially removing those objects from the kernel. -
17
go-toml
Go library for the TOML file format
Go library for the TOML format. This library supports TOML v1.0.0. Full API, examples, and implementation notes are available in the Go documentation. As much as possible, this library is designed to behave similarly as the standard library's encoding/json. While go-toml favors usability, it is written with performance in mind. Most operations should not be shockingly slow. Decoder can be set to "strict mode", which makes it error when some parts of the TOML document was not present in the target structure. This is a great way to check for typos. When most decoding errors occur, go-toml returns DecodeError), which contains a human readable contextualized version of the error. TOML supports native local date/times. It allows to represent a given date, time, or date-time without relation to a timezone or offset. To support this use-case, go-toml provides LocalDate, LocalTime, and LocalDateTime. -

Ebiten
A dead simple 2D game library for Go
Ebiten is an open source game library for the Go programming language. Ebiten's simple API allows you to quickly and easily develop 2D games that can be deployed across multiple platforms. In Ebiten, everything is an image: the screen, data from an image file, and even offscreen items are all represented as image objects. Most rendering operations consist of drawing one image on top of another. Ebiten games work on desktop (Windows, macOS, Linux, and FreeBSD), web browsers (through WebAssembly), and even on mobile (Android and iOS)! Plus, Ebiten is implemented in pure Go on Windows, so Windows developers do not need to install a C compiler. Nintendo Switch™ is also supported! While Ebiten's drawing API is very simple, Ebiten games run very fast with GPU power. Multiple images are integrated into a texture atlas internally, and drawing operations are automatically performed in batch when possible. -

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. -

go-datastructures
A collection of useful, performant, and threadsafe Go datastructures
Go-datastructures is a collection of useful, performant, and threadsafe Go datastructures. Interval tree for collision in n-dimensional ranges. Implemented via a red-black augmented tree. Extra dimensions are handled in simultaneous inserts/queries to save space although this may result in suboptimal time complexity. Intersection determined using bit arrays. In a single dimension, inserts, deletes, and queries should be in O(log n) time. Bitarray used to detect existence without having to resort to hashing with hashmaps. Requires entities have a uint64 unique identifier. Two implementations exist, regular and sparse. Sparse saves a great deal of space but insertions are O(log n). There are some useful functions on the BitArray interface to detect intersection between two bitarrays. This package also includes bitmaps of length 32 and 64 that provide increased speed and O(1) for all operations by storing the bitmaps in unsigned integers rather than arrays. -

ws
Tiny WebSocket library for Go
Zero-copy upgrade. No intermediate allocations during I/O. Low-level API which allows building your own logic of packet handling and buffers reuse. High-level wrappers and helpers around API in wsutil package, which allow to start fast without digging the protocol internals. Existing WebSocket implementations do not allow users to reuse I/O buffers between connections in clear way. This library aims to export efficient low-level interface for working with the protocol without forcing only one way it could be used. Library is tagged as v1* so its API must not be broken during some improvements or refactoring. Example applications using ws are developed in separate repository ws-examples. We can apply the same pattern to read and write structured responses through a JSON encoder and decoder.Zero-copy upgrade helps to avoid unnecessary allocations and copying while handling HTTP Upgrade request.
