Cursor 3 grew from a change in how the Cursor team itself built software: more work was being delegated to agents, but engineers still had to manage scattered conversations, terminals and windows. Released in April 2026, the new interface brought those agents into a unified workspace across repositories.
The team built this surface from scratch after starting the original Cursor as a VS Code fork. Moving work between local and cloud environments, reviewing changes and inspecting demonstrations became central parts of the workflow. The familiar IDE remained available for developers who needed to move back into the code.
