23 Best Google ADK Alternatives & Competitors (2026)
The top alternatives to Google ADK in the Agent Frameworks space, compared on features, pricing, and what they're best at.
Updated March 10, 2026
Why look beyond Google ADK?
Google's Agent Development Kit (ADK) is a flexible and modular framework launched in 2024 for developing and deploying AI agents using a code-first approach. The ADK was designed to make agent development feel more like traditional software development, enabling developers to create, deploy, and orchestrate agentic architectures ranging from simple tasks to complex multi-agent workflows. Available for both Python and TypeScript, ADK emphasizes writing clean, testable, and maintainable code rather than relying heavily on prompt engineering.
Common reasons users explore alternatives
- Optimized primarily for Google Cloud ecosystem
- May be overly structured for simple use cases
- Less flexibility for multi-cloud or non-Google deployments
