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.

Recall
Find any file on your machine with a sentence — no tags, no indexing

Recall is a local-first multimodal semantic search tool that lets you find any file on your computer using natural language — images, PDFs, audio, video, and text — without any manual tagging, folder organization, or metadata. Ask "that invoice from the dentist last spring" or "photo of the whiteboard with the Q3 roadmap" and it surfaces the right file. Under the hood, Recall uses Google's Gemini Embedding 2 to generate semantic embeddings for all your files and stores them in ChromaDB, a local vector database that runs entirely on your machine. Nothing leaves your device. The Raycast extension adds a visual grid UI so you can search from anywhere on macOS without opening a terminal. First-run indexing can take 20-30 minutes for large libraries, but subsequent queries are near-instant. The project is MIT-licensed and built by a solo developer. It's a clear response to the frustration that Spotlight, Find, and Windows Search still rely heavily on filename and metadata matching even in 2026. As Gemini Embedding 2 is free within generous limits, the operating cost is essentially zero for personal use.
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.”
“ChromaDB + Gemini Embedding 2 on local files is a setup I'd have spent a week configuring from scratch. Recall packages this cleanly with a Raycast extension that makes it actually usable day-to-day. The MIT license and zero vendor lock-in seal the deal for me.”
“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.”
“Re-indexing after file changes, cold-start latency on large libraries, and the dependency on Gemini Embedding 2 (which isn't truly offline) are real friction points. Apple Intelligence already does some of this natively on-device. Wait for broader platform support before switching your file workflow.”
“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.”
“Semantic search for personal files is the foundation for personal AI agents. If your agent can find any piece of information you've ever touched, you unlock genuine memory at human-years scale. Recall is primitive but points at something important.”
“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.”
“I have 80,000 photos, hundreds of PDFs, and years of Figma exports I can never find. The idea of describing an image or document and having it surface immediately is worth every minute of setup time. This is the dream of local AI finally shipping.”
