astro-html-editorSelf-hosted HTML editor with live preview

Paste or write HTML, see the result instantly. Files land on the server filesystem — no localStorage, no manual download.

Server-side persistence

Every keystroke (debounced) and every paste (immediate) writes to the server filesystem via node:fs. No browser storage involved.

No React, Vue, or Svelte. The editor is a textarea and the preview is an iframe. Fast, portable, easy to audit.

Files are written to a tmp path first, then renamed. A crash mid-write leaves the previous version intact.

Each file gets a permanent URL at /file/YYYY-MM/name. Paste the URL into another tab to reopen exactly where you left off.

New, Save As, Rename, Clone, Load, Copy, Download, Reset, and Open in new window — all from the toolbar.
