Browser Use vs Google Agent Development Kit (ADK)

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Browser Use Agents	Google Agent Development Kit (ADK) Agents
Tagline	Open-source browser automation harness and cloud platform for LLM agents that drive real websites.	Google's open-source framework for building, evaluating, and deploying production AI agents
Category	Agents	Agents
Pricing	Freemium· Pay as you go: $0 · Dev: $29/mo · Business: $299 · Scaleup: $999	Free· Framework itself is free and open-source (Apache 2.0). Costs come from the underlying model provider (e.g. Gemini API / Vertex AI usage) and any hosting infrastructure (Cloud Run, GKE, Agent Engine).
Model	Multi-model (BYO LLM; Claude in hosted Box)	Gemini (default) plus Claude, GPT-4/5, Llama, and other providers via LiteLLM

Pros	Open-source core with a large, active community Model-agnostic: works with OpenAI, Anthropic, Gemini, or local LLMs Hosted stealth browsers and proxies handle anti-bot defenses Structured DOM representation keeps token costs reasonable Backed by serious funding and Fortune 500 adoption	Genuinely open-source (Apache 2.0) with active Google engineering behind it, not a hosted-only product Multi-language: first-class Python, Java, and Go SDKs — rare among agent frameworks that are usually Python-only Built-in dev UI (`adk web`) with trace inspection, event stream, and session replay speeds up debugging enormously Model-agnostic via LiteLLM — Gemini is default but Claude, GPT, and local models plug in cleanly Rich multi-agent primitives out of the box: SequentialAgent, ParallelAgent, LoopAgent, and hierarchical sub-agents Tight Google Cloud integration for deployment (Cloud Run, GKE, Agent Engine) plus native BigQuery/Vertex Search tools Evaluation harness with trajectory-level scoring is included, not a separate paid add-on First-class MCP (Model Context Protocol) client and server support
Cons	Cloud pricing scales fast for high-volume agent runs Agents still drift or loop on complex multi-step flows Stealth/proxy use lives in a legal grey area for many sites	Documentation and examples lean heavily on Gemini + Google Cloud; non-Google paths work but feel like second-class citizens API surface is still evolving — breaking changes between minor versions have been common through 2025-2026 Multi-agent orchestration primitives are powerful but the graph/callback model has a real learning curve compared to a plain prompt loop Agent Engine deployment is convenient but locks you into GCP billing and quotas TypeScript/Kotlin support lags the Python SDK in features and community examples
