AI 原生代码编辑器，基于 VS Code 分叉改造，Tab 补全与 Agent 模式可跨文件理解整个仓库并自动改写，是目前 AI 编程的标杆产品。

全仓库理解和多文件改写确实改变开发习惯，Tab 补全手感最好；重度 Agent 使用要留意额度，让它大改前先 commit。

An AI-native code editor built as a fork of VS Code, so your existing extensions and keybindings carry over. Its distinguishing feature is repository-wide indexing: it understands how files relate across a project rather than only the file you have open, which makes multi-file refactors and "where is this defined" questions work properly.

The most balanced coding tool overall, and the one I would recommend first to most developers.

Where it winsRepo-wide context. Asking it to rename a concept across twelve files, or to trace why a build is failing, is where the indexing pays off and where chat-window assistants fall down. The VS Code base means near-zero migration cost.

Where to be carefulIt is a subscription on top of your model costs, and the agent mode can be over-eager — it will happily make changes you did not ask for, so keep the diff view open. Very large monorepos can get sluggish.

VerdictThe default recommendation for day-to-day development. If you prefer the terminal, Claude Code or Codex are stronger there; if you want maximum control over which model you use, an open-source agent is the better fit.
