Zed Delta is a standalone agent interface rather than a conventional editor with chat attached. Projects are organized around threads, and DeltaDB records the operations between commits so a developer can move from a line of code to the conversation that produced it, or from a conversation back to the corresponding changes.
The app remains compatible with existing Git repositories while adding multiplayer collaboration through CRDTs. Teammates can join a shared thread, inspect its history, edit prompts and continue working with the same agent. A WebAssembly browser version uses the same Rust application without requiring a local installation.
In the demonstration, the agent inspects a new Next.js project, asks clarifying questions, writes and commits a design specification and implementation plan, then works inside an isolated DeltaDB-backed clone. It checks the project baseline, consults bundled framework documentation, writes tests first and commits each stage while keeping the thread and repository history synchronized.
Delta can use hosted models, a ChatGPT subscription, API keys or GitHub Copilot, and it also supports Claude Code sessions through the Agent Client Protocol. Cloud runners can continue after a laptop closes. The product was still in early access with unannounced pricing, while Zed said DeltaDB would be open sourced with optional paid services. Closing membership and donation requests are omitted.
