Google ADK vs Zed 1.0

Google's Agent Development Kit (ADK) is an open-source Python framework that brings software engineering discipline to AI agent development. It takes a code-first approach — developers define agent logic directly in Python, making agents testable, composable, and deployable across different environments without lock-in. ADK supports pre-built tools, custom functions, OpenAPI specs, and MCP integrations. It's designed for multi-agent architectures where specialized sub-agents are orchestrated into scalable hierarchies. A built-in development UI makes local testing and debugging far easier than most competing frameworks, and Cloud Run and Vertex AI deployments are first-class deployment targets. With 19,300+ stars and an Apache 2.0 license, ADK is gaining real traction. While optimized for Google's Gemini models, it's designed to be model-agnostic — an important choice that signals Google understands developers want flexibility, not a guided tour of their cloud bill.

Zed — the Rust-built, GPU-accelerated code editor — has officially shipped version 1.0. Co-founded by Nathan Sobo (creator of the original Atom editor), Zed was purpose-built from scratch to be the fastest collaborative editor while being AI-ready by design. The 1.0 milestone marks what the team calls the completion of their founding vision. The AI features have matured significantly: users can now run multiple AI agents in parallel within the same window, each editing different parts of a codebase simultaneously. Zed also ships Zeta — an open-source, on-device model for edit prediction that anticipates your next changes without a round-trip to the cloud. Claude Code and major LLM providers are all natively supported. What sets Zed apart from VS Code forks is the architecture: it's multi-threaded, uses a custom GPU rendering engine, and treats collaboration as a first-class primitive. With 1.0 out, the team is publishing weekly agent adoption metrics publicly — a transparency move that's unusual in the editor space.
