adk-python vs metaharness
adk-python: ADK (Agent Development Kit) is an open-source, code-first Python framework designed for building, evaluating, and deploying sophisticated AI agents with high flexibility and control. It simplifies the creation and orchestration of agent workflows, supporting everything from simple tasks to complex multi-agent systems, while being model and deployment agnostic.; metaharness: MetaHarness is a CLI and browser Studio that mints custom AI agent harnesses from any GitHub repository, creating a repo-aware CLI, coding agent, and local MCP server tailored to the project. It acts as a factory for agent frameworks, allowing users to ship their own branded, npm-publishable AI agents with custom memory, governance, and model routing.
