Zed has launched Delta, a new multiplayer environment for coding with AI agents and reviewing their output, now open for private beta signups. Built on DeltaDB, a real-time database that syncs conversations and code together, Delta lets teams comment on any line of code or conversation, invite collaborators into threads, run agents in the cloud, and connect to third-party agent harnesses like Claude Code. Delta is a standalone Rust application (compiled to WebAssembly for browser use), separate from the Zed editor, though DeltaDB capabilities will eventually come to Zed too.

What is Delta from the Zed team and how is it different from the Zed editor?
Delta is a new standalone multiplayer application for coding with AI agents and reviewing their work, built by the Zed team, currently in private beta. Unlike Zed the code editor, Delta centers the conversation with agents rather than the editor, runs on DeltaDB (a real-time database that syncs code and conversation together), and is a separate Rust app compiled to WebAssembly for browser access. daily.dev tracks new agentic coding tools like Delta as teams evaluate where AI-assisted workflows are heading.
Does Delta integrate with Claude Code for agentic coding sessions?
Yes, Delta connects to third-party agent harnesses starting with Claude Code. Developers can keep working in their existing terminal, and the session syncs live into a Delta thread, letting teammates watch the conversation and code evolve, comment in place, and pick up the work with full context. developers weighing agent harness integrations can follow tools like Claude Code and Delta on daily.dev.
