Honest, side-by-side comparisons. We name what each tool does well before the contrast.
Cursor puts the agent inside a forked editor. Vesper Code puts it in the terminal, next to git, your tests, and your build, so it composes with the rest of your workflow and you keep the editor you already use.
Both are terminal-native. The difference is the loop: Vesper Code splits work across specialized agents and runs an independent reviewer with fresh context before a change reaches you.
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.
Both are open source. Vesper Code differs in the loop: a dedicated planner and an independent reviewer reduce the babysitting an autonomous single agent often needs.
