Google's Agent Development Kit (ADK) Python hit v1.0.0 stable on April 17, marking it production-ready for teams building and deploying AI agents at scale. ADK is a modular, code-first framework that applies standard software engineering principles to agent development — graph-based workflow execution, structured agent-to-agent delegation via a Task API, native MCP support for tool integration, and built-in evaluation tooling. Unlike LangChain's general-purpose orchestration or CrewAI's role-based crews, ADK leans into composable determinism: you define explicit graphs of agent behavior that are auditable, testable, and deployable directly to Google Cloud's Vertex AI Agent Engine. It supports Python, TypeScript, Go, and Java, making it one of the few multi-language agent frameworks in production. The 1.0 stable label matters. Google has been iterating ADK roughly every two weeks, and teams that held off on building with it due to API instability now have a stable target. With Vertex AI providing the deployment layer and Agent Engine handling orchestration at scale, this is Google's full-stack answer to the agent infrastructure question.

Langfuse provides LLM observability, prompt management, evaluations, and datasets. Open source with a managed cloud option. The leading open alternative to LangSmith.
Reviewer scorecard
“The 1.0 stable tag finally gives us something to build on. The graph-based execution engine is exactly what I want for deterministic multi-step pipelines where I can't afford unpredictable LLM routing. Native MCP support means my existing tool ecosystem plugs straight in without adapter layers.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“ADK's tight coupling to Vertex AI is a genuine lock-in concern. The 'production-ready' badge comes with an implicit 'on Google Cloud' qualifier. For teams running on AWS or Azure, the deployment story is clunky. LangGraph and CrewAI are more cloud-agnostic and have larger community ecosystems right now.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Google going stable on a multi-language agent framework signals they're treating this as core infrastructure, not a demo. The Agent-to-Agent (A2A) protocol work alongside ADK hints at Google's real play: defining how agents communicate at internet scale, the same way HTTP defined how documents communicate.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“For no-code and low-code builders who want to graduate to real agent workflows, ADK's structured graph model is more approachable than writing raw LangChain chains. The TypeScript version in particular opens this to a much wider pool of front-end developers who want to add agentic features to their apps.”
