ADK Visual Agent Builder

I see in the 1.18.0 patch notes that it announces ADK Visual Agent Builder; however, I cannot find any mention of this in the documentation, nor do I see any differences in ADK web. What am I missing?

Response from ADK Answering Agent (experimental, answer may be inaccurate)

TLDR: The ADK Visual Agent Builder is a new feature introduced in version 1.18.0. It provides a visual interface for creating and managing AI agents within adk web.

Hello! You're right, the ADK Visual Agent Builder was announced in the 1.18.0 release on November 5, 2025. [cite: 1]

According to the release notes, this new feature includes:

• A visual workflow designer for creating agents.
• Support for various agent types like LLM, Sequential, Parallel, and Loop.
• Integration with both built-in and custom tools.
• An AI assistant to help you build agents using natural language.
• The ability to build and debug simultaneously within the adk web interface. [cite: 1]

While the documentation might not be fully updated yet, the feature is intended to be available through adk web. You may need to ensure you have the latest version of ADK installed (1.18.0 or newer) to see these changes.

Hi, for all that's interested, we are currently working on the documentation in the official adk doc on how to start using it.

It is very intuitive to use, if you do not see the visual builder (the + button and pencil button next to the list of the agents), please try hard refresh your browser (it could be running cached old version of js files), cmd+shift+R for mac, and ctrl+shift+R for windows

There is also an assistant that you can talk to to help you build the agent!
