Google Agent Development Kit (ADK) vs Superpower ChatGPT

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

	Google Agent Development Kit (ADK) Agents	Superpower ChatGPT Agents
Tagline	Google's open-source framework for building, evaluating, and deploying production AI agents	Chrome extension that bolts folders, prompt libraries, and bulk export onto the ChatGPT web UI.
Category	Agents	Agents
Pricing	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).	Freemium· Basic: $10 · Pro: $20 · Enterprise: Contact sales
Model	Gemini (default) plus Claude, GPT-4/5, Llama, and other providers via LiteLLM	GPT (via ChatGPT UI)
Editorial score	—	7.0 / 10

Pros	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	Folders, search, and prompt library that the native ChatGPT UI lacks Bulk export to PDF, Markdown, JSON, and TXT Prompt queue lets you chain sequential prompts unattended Conversation tree map makes branched chats navigable Mature with 100K+ users and active development
Cons	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	Only works with ChatGPT, not Claude or Gemini Breaks occasionally when OpenAI ships UI changes Some advanced features gated behind Pro Browser extension means desktop Chrome/Edge only
