Open Source CI/CD Software Delivery Platform

Harness Gitness is an open-source end-to-end developer platform that combines Git source control management, CI/CD pipelines, hosted developer environments (Gitspaces), and artifact registries for engineering teams seeking a self-hosted DevOps solution.

🚀 Overview

Gitness is a platform-agnostic, open-source DevOps platform built by Harness that provides a unified experience for code hosting, collaboration, automation, and delivery. It evolved from the Drone CI project, adding full Git repository management, cloud dev environments, and artifact handling while maintaining Drone's powerful pipeline engine.

This project solves the fragmentation in DevOps tools by offering an all-in-one self-hosted alternative to proprietary SaaS like GitHub + GitHub Actions + package registries, ensuring data sovereignty, customization, and no vendor costs. It eliminates local setup hassles with instant Gitspaces and prevents environment inconsistencies.

It's built for developers, engineering teams, and organizations of all sizes who need scalable, secure CI/CD without lock-in. Harness created it to provide enterprise-grade open-source tools, enabling faster, reliable software delivery.

✨ Key Features

Git repositories with commits, branches, pull requests, code reviews, security (secrets scanning, protected branches), and webhooks
Production-ready CI/CD pipelines for any language/platform (Linux/Windows/Mac), with reusable YAML templates for Java, Go, Node, Rust, Android, Docker
