# Omnigent > Omnigent is an open-source meta-harness for AI agents. It provides a common layer over Claude Code, Codex, Pi, and custom agents, with shared sessions, contextual policies, OS sandboxing, model and credential configuration, real-time collaboration, and multiple interfaces. Use this file to find the most relevant Omnigent documentation for coding agents, custom agents, deployment, collaboration, policies, sandboxing, and end-user interfaces.
