Best open-source alternatives to GitHub

Gitea is a self-hosted Git service designed to provide a simple and fast way to run a private code hosting platform. It is written in Go and supports the operating systems and architectures commonly supported by Go, including Linux, macOS, Windows, x86, amd64, ARM, and PowerPC. The project is aimed at users and teams who want to host repositories and collaborate without relying on a third-party platform. The README points to a public demo, a free hosted service with limited repositories, and a cloud trial for dedicated instances, while also directing users to extensive documentation for installation, administration, usage, development, and localization. It additionally notes experimental API support and lists companion projects such as a CLI tool, SDK, and action runner.

Gogs is a self-hosted Git service aimed at being simple to deploy, stable to operate, and extensible for customization. It is positioned for users and teams who want a private Git hosting solution with a relatively painless setup, and it emphasizes portability through an independent Go binary that runs on Linux, macOS, Windows, and ARM-based systems. The project includes the common collaboration features expected from a Git hosting platform, such as repository management, issues, pull requests, wiki support, webhooks, deploy keys, and Git LFS. It also supports multiple authentication methods, database backends, and localization, making it suitable for small teams or organizations that want to self-host source control and integrate with existing workflows. The README also points to experimental API documentation and a live online demo.

All-In-One DevOps Platform. With Git Management, Issue Tracking, and CI/CD. Simple yet Powerful.

GitBucket is a self-hosted Git web platform built with Scala for teams and individuals who want a GitHub-like server they can run themselves. It focuses on ease of installation, an intuitive interface, and extensibility through plugins. The project provides repository hosting with public and private access over HTTP/HTTPS and SSH, along with Git LFS, an online file editor, issues, pull requests, wiki pages, activity timelines, and email notifications. It also supports account and group management with LDAP integration, and the README highlights API compatibility with GitHub plus a plug-in system for extending functionality. Deployment is centered on a runnable WAR file for Java 17, with support for servlet containers such as Jetty or Tomcat.

Self Hosted Git repository management, code reviews, issue tracking, activity feeds and wikis.

A lightweight software forge focused on scaling, federation, and privacy (fork of Gitea).

Opengist is a self-hosted pastebin platform built around Git, aimed at users and teams who want to manage text snippets in a version-controlled way. Instead of storing content in a traditional database-centric paste service, it keeps snippets inside a Git repository, allowing them to be read and modified through the web UI or standard Git workflows. The project supports common snippet-management features such as visibility controls, search, syntax highlighting, revision history, and social actions like likes and forks. It also includes login via OAuth2 providers such as GitHub, GitLab, Gitea, and OpenID Connect, making it suitable for deployments that need external identity integration. Installation is offered through Docker, binary downloads, source builds, and a Helm chart, with documentation and a public demo available.

walgit is a self-hosted Git server designed to run as a single binary backed by object storage. It targets repositories that may be larger than the machine serving them, using the bucket as the source of truth and treating each server instance as a disposable cache. The project is written in Rust and explicitly follows an architecture inspired by Cursor’s “Git at any scale” design. It is aimed at teams or operators who want Git hosting without a traditional database, leader election, or shared local state. The server provides smart HTTP, Git LFS, bundle-based cloning and fetch acceleration, a browser UI, a JSON API with an SDK, push policies, and webhook delivery. The README also describes maintenance and replication behavior, OIDC and token-based auth, and deployment options ranging from a local one-box setup to multi-machine deployments sharing the same bucket.

rgit is a web interface for browsing bare Git repositories, positioned as a modern alternative to gitweb or cgit. It is written in Rust and uses Axum, gitoxide, Askama, and RocksDB to present repository data efficiently while keeping metadata indexed for fast access. The project is aimed at users who want to self-host a lightweight Git browsing service over their own bare repositories. The README describes local deployment options including direct execution with Cargo, building from source, running on NixOS, and containerized operation with Docker or Docker Compose. It also explains repository configuration details such as descriptions, owners, exportability, and cache/database storage.

SCM-Manager is a self-hosted source control management application designed to help teams share and administer Git, Mercurial, and Subversion repositories. It presents itself as an easy-to-install alternative to manual repository hosting setups and emphasizes browser-based administration rather than editing configuration files directly. The project includes centralized user, group, and permission management, a rich web UI, and a full RESTful web service API for integration. It also supports plugins and ships distribution modules for multiple deployment targets, including Docker and Helm. The README points users to the main documentation site and community support resources, and it mentions enterprise support as an available paid service.
