When writing unit-tests for an object, it is often useful to have fake implementations of the object's collaborators. In go, such fake implementations cannot be generated automatically at runtime, and writing them by hand can be quite arduous.

counterfeiter allows you to simply generate test doubles for a given interface.

A Machine Learning library written in pure Go designed to support relevant neural architectures in Natural Language Processing.

Spago is self-contained, in that it uses its own lightweight computational graph both for training and inference, easy to understand from start to finish.

Fully featured and highly configurable SFTP server with optional HTTP/S, FTP/S and WebDAV support. Several storage backends are supported: local filesystem, encrypted local filesystem, S3 (compatible) Object Storage, Google Cloud Storage, Azure Blob Storage, SFTP.

go-callvis is a development tool to help visualize call graph of a Go program using interactive view.

Vale is a command-line tool that brings code-like linting to prose. It's fast, cross-platform (Windows, macOS, and Linux), and highly customizable.

The etree package is a lightweight, pure go package that expresses XML in the form of an element tree. Its design was inspired by the Python ElementTree module.

Memphis enables building modern queue-based applications that require large volumes of streamed and enriched data, modern protocols, zero ops, up to x9 faster development, up to x46 fewer costs, and significantly lower dev time for data-oriented developers and data engineers.

A collection of useful, performant, and threadsafe Go datastructures.

Gain is a high-performance io_uring networking framework written entirely in Go.

Lancet is a comprehensive, efficient, and reusable util function library of go. Inspired by the java apache common package and lodash.js.

DNSControl is a system for maintaining DNS zones. It has two parts: a domain specific language (DSL) for describing DNS zones plus software that processes the DSL and pushes the resulting zones to DNS providers such as Route53, Cloudflare, and Gandi. It can send the same DNS records to multiple providers. It even generates the most beautiful BIND zone files ever. It runs anywhere Go runs (Linux, macOS, Windows). The provider model is extensible, so more providers can be added.

A high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar.
