Cursor vs. Claude Code: IDE or terminal

Cursor is built for a short loop: select, ask, inspect the diff, revise. Its agent searches the codebase, edits files, runs the terminal, and uses a selected model. Project Rules and AGENTS.md provide persistent architectural context.

Cloud Agents can work in an isolated VM, install dependencies, run tests, and attach logs, screenshots, or video—useful when a green unit test is not enough.

Claude Code fits naturally into a terminal. It sees the repository, runs commands, and can integrate with an IDE, but interaction remains text-first and scriptable. Checkpoints support rollback, hooks run checks, and subagents isolate research.

This approach combines well with shell tooling, CI, and remote environments and is less dependent on a particular editor.

When a task starts from a visual defect, Cursor usually offers the more direct loop: code, diff, terminal, and image are close together. When the task is a reproducible procedure—upgrade a package, run a codemod, repair types, and execute a suite—the terminal-first model often feels more natural.

The decision is about where you want to stand during the work: inside the editor or above the process.

A cloud agent may need repository, network, and secret access. Prompt injection is a real risk when commands run automatically. A local agent is not safe by default either.

Use least privilege, a separate branch or worktree, secrets only when necessary, and mandatory human review. Convenience should never replace a threat model.
