About The Agent Development Kit (ADK) is a flexible, open-source framework for building and deploying AI agents. It is tightly integrated with Google’s ecosystem, including Gemini models, and supports popular large language models (LLMs). ADK simplifies the development of both simple and complex AI agents, providing a structured environment for building dynamic workflows and multi-agent systems. With built-in tools for orchestration, deployment, and evaluation, ADK helps developers create scalable, modular AI solutions that can be easily deployed on platforms like Gemini Enterprise Agent Platform or Cloud Run.	About FlowRunner is a visual workflow automation platform with native AI agent orchestration. Agents run workflows autonomously and pause for human judgment where it is required. The difference is how oversight works. On most platforms, approval is a step the workflow passes through. In FlowRunner, an agent invokes a human as a callable tool at runtime: it assembles the context and choices, routes to a named person by email, Slack, WhatsApp, or phone, and resumes with the answer. A run can stay suspended for up to a year, so a decision that takes three days does not time out. Audit trails, RBAC, and SLA tracking arrive at mid-tier, not in a custom enterprise contract, and a BAA is available. Every tier includes unlimited users, unlimited workflows, and the entire integration catalog, with nothing gated by seat or connector. Billing is per workflow run, not per action step. Agents use your own AI provider keys, with no markup on inference. Cloud-hosted or self-hosted.

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.
