Copilot has the deepest editor integration and the broadest reach. Inline suggestions and Copilot Chat are mature and well supported across IDEs.
Copilot is built around autocomplete and chat inside the editor. Vesper Code is built for codebase-spanning changes you run from the terminal, planned and reviewed, not typed one suggestion at a time.
