bienphiendoan is a small site for hosting interactive HTML tools, visual demos, and one-off utilities — the kind of thing that would otherwise live as an orphan CodePen.
Principles
Static, fast, and honest. Each tool is a folder of plain HTML, CSS, and JavaScript — no build step, no analytics pixels, no third-party trackers. If a tool needs a server, that comes later and is opt-in per tool.
How it's hosted
Cloudflare Pages on the apex domain. Pushes are one command from the local source folder; routing is whatever the file tree says it is. There is no CMS.
Contact
For now, the site is intentionally one-way. A contact channel will be added if and when it's useful.
