Delta

A multiplayer coding environment where developers and AI agents collaborate in shared threads with full context.

Delta is a multiplayer development environment built by Zed Industries that brings developers and AI agents together in shared, synchronized threads. Unlike traditional code editors, Delta treats the conversation and the codebase as one unified, replicated workspace powered by DeltaDB. Teams can invite teammates into live threads to review, comment, and work alongside agents in real time, with every prompt and decision preserved alongside each code change. This means code review begins with full context rather than a cold diff. Delta runs on desktop, web, or cloud runners, keeping conversation and code continuously synchronized across environments. It is designed from the ground up for the way modern software development actually works.
