Ace is an embeddable high‑performance code editor written in JavaScript for the web. It provides syntax highlighting, code folding, multiple cursors and customizable key bindings similar to native editors.
Use cases
- Embed a full‑featured code editor in a web application
- Provide syntax highlighting for dozens of programming languages in a browser
- Add Vim or Emacs key‑binding support to an online editor
- Enable live code editing with auto‑completion and code folding in a SaaS product
- Create a customizable code playground or tutorial platform
When to choose
- You need a lightweight, client‑side editor that can be dropped into any web page
- Your project requires support for many language modes and themes out of the box
- You want customizable key bindings (Vim, Emacs) and advanced features like multiple cursors
- You prefer a BSD‑licensed solution with an active community
When to avoid
- You need a full IDE with integrated debugging, project management, or server‑side compilation
- Performance on extremely large files (hundreds of MB) is a critical requirement
- You require native desktop or mobile applications without a browser environment
