Pros & Cons from Real Users Pros ADK feels like a serious framework for people who want to build real agents, not just quick demos. It gives developers a structured way to define agents, connect tools, coordinate multi-agent workflows, and move from local testing toward production. I like that it is open source and supports multiple languages. Python is great for AI work, but TypeScript, Go, Java, and Kotlin support make ADK more realistic for teams building inside existing engineering stacks. The production focus is the biggest advantage. ADK is built around debugging, evaluation, deployment, and reliability, which are exactly the things teams need once an agent goes beyond a prototype. Cons ADK may be more framework than you need for a simple chatbot or one-off automation. If the use case is small, a lighter tool may be faster to set up.
