Delta
Points and comments are a snapshot, not live.
Zed announces Delta, a multiplayer environment for coding with agents and reviewing their work.
Delta is a new application from the Zed team, built on DeltaDB, which replicates conversations and the worktree in real time. It connects code and conversations, allowing developers and agents to collaborate with full context. DeltaDB works with existing git repositories, capturing edits between commits. Delta features in-place comments anchored to evolving code, thread sharing with browser access via WebAssembly, and integration with third-party agent harnesses like Claude Code. The thread, not the editor, is the center of the application. A private beta is now accepting signups.
Zed chose to build a separate application instead of adding DeltaDB directly to Zed to avoid disrupting existing users and to iterate quickly on the new primitives.
What commenters are saying
Many commenters are skeptical about the verbosity of AI code summaries, finding that long prose often obscures rather than clarifies. Several observe that reading a paragraph to understand a few lines of code is inefficient, and that summaries frequently miss edge cases. Some commenters note that the value of AI summaries depends heavily on careful prompting to be concise. Others argue that while raw AI output is poor, a rewriting pass can yield useful results. A few commenters question the product's timing, suggesting that rapid advances in frontier models may have overtaken Delta's vision. One camp prefers manual coding and finds AI-generated code buggy and frustrating.
