Comparison
vs CodePen / JSFiddle / StackBlitz
Cloud editors. Your files live on their servers, subject to their terms, their uptime, and their account system. astro-html-editor is self-hosted — files are on your machine.
vs VS Code + Live Server
VS Code is a full IDE with syntax highlighting, IntelliSense, extensions, and multi-file projects. astro-html-editor is a single-purpose tool: one file, one preview, in a browser tab. No install beyond Node.js, no local port conflicts to manage.
If you're working on a multi-file project, use VS Code. If you want to paste a snippet and see it render without switching applications, use astro-html-editor.
vs saving files locally and refreshing
The traditional approach: edit in a text editor, save, switch to browser, refresh. astro-html-editor removes the switch-and-refresh step. The preview is always current.
vs Monaco Editor-based tools
Monaco (the VS Code editor component) is around 3-5 MB of JavaScript. It adds syntax highlighting, IntelliSense, and multi-cursor editing. It also adds complexity: a web worker, a language server protocol shim, and significant initial load time.
astro-html-editor uses a plain textarea. Tab handling and line numbers are the only custom behavior. The entire client-side script is under 4 KB. On a slow connection or a low-spec machine, this matters.
