JetBrains and Zed Join Forces: A Unified Language for AI Agents in the IDE (The ACP of the LSP World)
JetBrains and Zed are collaborating on the Agent Client Protocol (ACP), a new open standard designed to allow AI agents to work seamlessly across any code editor or IDE.

Think of it like the Language Server Protocol (LSP), but for AI. Just as LSP standardized features like autocomplete and syntax highlighting, ACP aims to do the same for AI-powered coding assistants.
The protocol enables AI assistants to understand and interact with IDEs directly. It defines a universal standard for how agents can perform tasks like writing, refactoring, and running code, as well as how they present information back to the developer.
Key Benefits for Developers
- No Vendor Lock-In: Choose your preferred AI agent and IDE independently.
- Developer in Control: The IDE remains the central hub, allowing you to review agent plans, view diffs, and approve all actions before they are executed.
- Seamless Workflow: The protocol is built with support for streaming and transparency to fit naturally into your existing development process.
- Collaborative Effort: JetBrains is leading the user experience (UX) design while Zed spearheads the protocol's open-source development.
This initiative is a major step toward creating a unified ecosystem where AI assistants can work natively across all development tools.
