Harness

Harness is a software delivery platform using AI agents to automate pipelines, manage security testing, enforce runtime protection, and optimize cloud costs.

Harness provides an autonomous platform for managing software delivery lifecycles. It utilizes specialized AI agents to handle tasks like pipeline automation, code quality checks, and risk governance. The software delivery agent manages changes from commit to production, while the security testing agent identifies vulnerabilities and supply chain risks. Users can implement runtime protection for APIs and AI agents, alongside cost management tools that track cloud spend by token and outcome. Policy-as-code guardrails based on OPA define operational boundaries, allowing organizations to maintain human oversight or full autonomy based on configured levels.
