Zed – The editor for what's next
Zed's goal is to make your codebase a living, navigable history of how your software evolved, where discussions with humans and AI agents are durably linked to the code they reference and always up-to-date. It's an evolution beyond version control that incorporates not just the code itself, but also the background information of how and why the code got into a particular state—context that AI agents can query to make more informed edits, understanding the assumptions, constraints, and decisions that shaped the existing code.
