Zed 1.0 Ships. The Editor That Was Built for Agents From Day One
Zed dropped its 1.0 on April 29 after years in beta. The headline is the version number. The actual story is that the editor team has spent the last twelve months retrofitting their performance-first Rust editor into the most agent-native code editor on the market. They beat Cursor and Copilot to the punch on a few specific things, and 1.0 is them planting the flag.
What ships in the box: Parallel Agents — multiple coding agents running in the same window across different projects, which Zed launched April 22. ACP support — the open Agent Client Protocol — so you can plug in Claude Agent, Codex, OpenCode, and anything else that speaks the spec without a custom integration. MCP server connections, Edit Prediction trained on their own open-source LLM. The whole thing is GPL'd at github.com/zed-industries/zed.
The positioning move worth naming is the protocol bet. Cursor went vertical — they own the editor, the agent, the IDE-as-a-product story. Zed is going horizontal — bring your own model, bring your own agent, the editor's job is to be the place where multiple agents work alongside humans. ACP is the open-protocol counter to Cursor's closed loop. If ACP wins, Zed sells the substrate; if Cursor wins, Zed sells nothing. That's a real bet, not a marketing line.
For the running tally: this is the seventh concrete data point in the agent-client-layer thesis in two weeks — Warp open source, Devin for Terminal, OpenAI on Bedrock, Mistral Vibe, jcode, Browserbase Skills, and now Zed 1.0. The category is now real enough that the open-versus-closed split is the next thing to watch.
