Google Agent Development Kit (ADK) vs Superpowers

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

	Google Agent Development Kit (ADK) Agents	Superpowers Agents
Tagline	Google's open-source framework for building, evaluating, and deploying production AI agents	Opinionated agentic skills framework that turns coding agents into disciplined, spec-driven software engineers.
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· Free: $0 USD · Team: $4 USD per user/month · Enterprise: $21 USD per user/month
Model	Gemini (default) plus Claude, GPT-4/5, Llama, and other providers via LiteLLM	Multi-model
Editorial score	—	7.1 / 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	Works across Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI and more from one repo Forces spec-first, TDD and subagent review instead of vibe-coding Skills auto-trigger after compaction so the discipline survives long sessions MIT-licensed and installable from official plugin marketplaces Backed by a commercial entity (Primeradiant) for enterprise support
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	Opinionated methodology - fights you if you want quick throwaway scripts Quality depends on the underlying coding agent and model you point it at Documentation is harness-fragmented; setup differs per tool
