Agent Development Kit (ADK) vs Agent Governance Toolkit

Agent Development Kit (ADK) and Agent Governance Toolkit 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.

Agent Governance Toolkit

Policy enforcement, zero-trust identity, execution sandboxing, and reliability engineering for autonomous AI agents.

Attribute	Agent Development Kit (ADK)	Agent Governance Toolkit
Pricing	Free	Free
Free trial	No	No
Open source	No	No
Has API	Yes	Yes
Self-hosted option	Yes	Yes
Platforms	Python, TypeScript, Go, and Java	Available in Python, TypeScript, Rust, Go, and .NET
Languages	Python, TypeScript, Go, and Java	Python, TypeScript, Rust, Go, and .NET
Released	2025-04	2026-04-02
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	First toolkit to address all 10 OWASP agentic AI risks with deterministic, sub-millisecond policy enforcement Framework-agnostic from day one, hooks into framework native extension points so adding governance does not require rewriting agent code Available across language ecosystems with TypeScript SDK through npm and .NET SDK through NuGet Structured as monorepo with independently installable packages allowing incremental adoption Ships with 9,500+ tests and includes SLSA-compatible provenance, OpenSSF Scorecard tracking, CodeQL scanning, and Dependabot dependency monitoring
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	Provides application-level governance, not OS kernel-level isolation; policy engine and agents run in same process, so production recommendation is to run each agent in separate container Toolkit is currently in public preview and may have breaking changes before GA Real-world production adoption evidence still limited (announced April 2026)

Bottom line

Agent Development Kit (ADK) and Agent Governance Toolkit are closely matched on pricing model, openness, and API availability — pick by feature set and platform support in the table above.
