Agent Development Kit (ADK) vs Langflow

Agent Development Kit (ADK) and Langflow are both agent frameworks tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Agent Development Kit (ADK)

ADK is the open-source agent development framework that lets you build, debug, and deploy reliable AI agents at enterprise scale.

Langflow

Open-source visual builder for constructing AI agents and RAG applications via drag-and-drop interface with Python extensibility.

Attribute	Agent Development Kit (ADK)	Langflow
Pricing	Free	Paid
Free trial	No	No
Open source	No	Yes
Has API	Yes	Yes
Self-hosted option	Yes	Yes
Platforms	Python, TypeScript, Go, and Java	Linux, macOS, Windows (Desktop); Cloud-agnostic (AWS, Azure, Google Cloud, etc.)
Languages	Python, TypeScript, Go, and Java	—
Released	2025-04	2023-02
Pros	Context is treated like source code with structured assembly of sessions, memory, tool outputs, and artifacts, automatic filtering of irrelevant events, summarization of older turns, lazy-loading of artifacts, and token usage tracking to keep agents fast, efficient, and reliable by default Multi-language support with Python, TypeScript, Go, and Java implementations Model-agnostic and compatible with other frameworks while optimized for Gemini Built-in development UI for testing, evaluating, debugging, and showcasing agents When deploying to Google Cloud, agents inherit managed infrastructure, built-in authentication, Cloud Trace observability, and enterprise-grade security without code changes	Fully open source (MIT license) with no vendor lock-in Visual builder reduces boilerplate while allowing full Python customization Extensive pre-built component library for major LLMs, databases, and APIs Deploy as API, MCP server, or JSON export for flexible integration Active development and enterprise backing (IBM/DataStax)
Cons	Optimized primarily for Google Cloud deployment and Gemini models, though model-agnostic capabilities exist Development version builds directly from latest code commits may contain experimental changes or bugs not present in stable release	Requires infrastructure management and DevOps knowledge for production deployment Steeper learning curve than some competing low-code platforms for non-technical users Cost complexity due to dependency on external services (LLM APIs, cloud hosting, vector databases)

Bottom line

Agent Development Kit (ADK) is free while Langflow is paid; Langflow is open source. Choose based on which difference matters most for your workflow.
