What is Harness?
Harness Open Source is an end-to-end development platform that integrates source code management, automated CI/CD pipelines, hosted development environments (Gitspaces), and artifact registries.
By evolving the legendary Drone CI, Harness provides a modern, cloud-native solution for teams building the next generation of AI-powered applications.

Harness AIDA
AI Development Assistant that automates log analysis, identifies security vulnerabilities, and generates code fixes in real-time.
Cloud Gitspaces
On-demand, pre-configured development environments for AI workloads. Standardize setups and eliminate "works on my machine" toil.
Model Registry
Store and manage not just containers, but AI/ML models with built-in versioning and dependency firewalls for safe consumption.
Model Context Protocol (MCP) Support
Harness integrates with MCP, allowing developers to manage pipelines, security, and cloud costs using natural language directly from their AI-powered IDEs (Cursor, VS Code) or CLI agents.
