Monaco Vim Keys — Jim

Monaco Vim Keys brings NeetCode-style editor settings to the Monaco code editors on popular coding practice sites. It attaches the mature monaco-vim keybinding engine to the editor the site already loads — no remote code, no account, nothing leaves your browser.

Features:

• Full vim key bindings (default ON): NORMAL/INSERT/VISUAL modes, motions (hjkl, w/b/e, 0/$, gg/G, counts), operators (d, c, y, x, r), undo/redo, o/O/A, / search, and more.
• Relative line numbers (default OFF).
• A subtle floating mode indicator (NORMAL / INSERT / VISUAL) next to the editor.
• Per-site enable toggles plus global Vim / relative-line-number toggles in the toolbar popup. Settings persist and apply instantly — no page reload.

Supported sites:

• leetgpu.com
• leetcode.com
• leetcode.cn
• www.hackerrank.com
• www.lintcode.com (caveat: older Monaco without getEditors(); vim attaches when the editor is created or recreated by the page)

Not supported on purpose: neetcode.io and codingame.com already ship native vim support; codewars.com, algoexpert.io, codeforces.com, exercism.org and atcoder.jp do not use the Monaco editor.

Unofficial project — not affiliated with or endorsed by any of the supported sites. Requests no permission besides "storage"; runs only on the listed sites.
