Introducing Delta: a multiplayer environment for coding with agents
Zed introduces Delta, a multiplayer environment for coding with agents, now in private beta. At its core is DeltaDB, which replicates both the conversation and the worktree in real time to every participant in a thread, while staying compatible with regular Git repositories. Every edit and conversation is captured between commits, so teammates who never open Delta still see a normal repo. Comments can anchor to any line of code and stay in place as the code evolves, connecting review to the conversation that produced it. The browser client is not a simplified port; it is the same Rust application compiled to WebAssembly and rendered through WebGL. Delta also integrates with third-party agent harnesses starting with Claude Code, syncing terminal sessions live into threads. The interface treats the conversation as an editable document, letting you place your cursor anywhere—on a diff line, a plan step, or a thinking block—and leave comments that the agent precisely understands. A product launch post with solid technical direction but limited hard data.
