cast
safe and easy casting from one type to another in Go
Cast is a Go library that provides easy and safe conversion (casting) between different types in Go programs. Especially when dealing with interface{} or dynamic/reflect-heavy code, it becomes cumbersome to assert types or convert values reliably; cast addresses that by offering a suite of functions to convert from any input to the target type with predictable behaviour. Rather than relying purely on raw type assertions, it offers ToInt, ToString, ToBool, ToTime, etc., and their “error-returning” counterparts like ToIntE. It is particularly useful when dealing with data from YAML, TOML, JSON or other formats where the type can be uncertain. The design choice is to avoid guessing about conversions: e.g., only a string strictly representing an integer can convert to int. The library is mature, tested, and widely used—thus ideal for projects that must handle dynamic input gracefully. -

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. -

Go Jsonnet
This an implementation of Jsonnet in pure Go
go-jsonnet is a pure Go implementation of the Jsonnet data templating language, which extends JSON with variables, functions, imports, and a standard library so you can generate complex configuration safely. Instead of hand-maintaining massive JSON files, you write concise, reusable templates that evaluate to JSON or YAML, with deterministic semantics and rich error messages. The repository ships both an embeddable VM for Go programs and a command-line interpreter, making it easy to integrate templating into build systems, CLIs, and services. Import paths and custom resolvers let you structure large configuration trees across directories or remote sources, while top-level arguments and external variables parameterize builds per environment. Native functions can be registered from Go to expose domain-specific helpers without forking the language. Tooling such as a formatter and linter-friendly errors encourages clean, consistent templates that scale across teams. -

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. -

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. -

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. -

Amazon EC2 Instance Selector
A CLI tool and go library which recommends instance types
A CLI tool and go library which recommends instance types based on resource criteria like vcpus and memory. There are over 270 different instance types available on EC2 which can make the process of selecting appropriate instance types difficult. Instance Selector helps you select compatible instance types for your application to run on. The command-line interface can be passed resource criteria like vcpus, memory, network performance, and much more and then return the available, matching instance types. If you are using spot instances to save on costs, it is a best practice to use multiple instances types within your auto-scaling group (ASG) to ensure your application doesn't experience downtime due to one instance type being interrupted. Instance Selector will help to find a set of instance types that your application can run on. -

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. -

Negroni
Idiomatic HTTP Middleware for Golang
Negroni is a middleware-focused library for Go with an idiomatic approach. It is similar to Martini, but comes in a small, non-intrusive package. Negroni is not a framework. It is designed to work directly with net/http. It is also BYOR (Bring Your Own Router), and plays well with most http routers available in the Go community by fully supporting net/http. Negroni is currently translated in a number of different languages, and comes with some default middleware that can be used for most applications and makes getting started with some of Negroni’s features a lot easier. -

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. -

Go Examples
Go(lang) examples
Now with an online live editor with Golang support. Try out and edit the examples directly in the browser. These examples explain the basics of Golang. There will be more examples from time to time. The examples are divided into three levels of difficulty. The Beginner section contains very easy examples, starting with Hello World but also containing a few easy algorithms. The Advanced section uses more complicated features of Golang. Finally, the Expert section contains applications like telnet-clients or http-server (even with SSL). If you want even more Golang examples, you can take a look at my other go repositories at GitHub. To execute a Golang program, write go run at the cli followed by the name of the file. You also can convert the file to a binary executable program by the command go build. One great aspect of Golang is, that you can start go applications via go run name.go, but also compile it to an executable with go build name.go. -

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. -

gqlgen
Go generate based graphql server library
gqlgen is a Go library for building GraphQL servers without any fuss. You get to Define your API using the GraphQL Schema Definition Language. You should never see map[string]interface{} here. We generate the boring bits, so you can focus on building your app quickly. Still not convinced enough to use gqlgen? Compare gqlgen with other Go graphql implementations. You need to tell gqlgen that it should only fetch friends if the user requested it. gqlgen will be able to automatically bind to strings or ints for models you have written yourself. gqlgen is a schema-first library, before writing code, you describe your API using the GraphQL Schema Definition Language. By default this goes into a file called schema.graphql but you can break it up into as many different files as you want. By default gqlgen will use any models in the model directory that match on name. -

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).
