md-to-html is a delightfully focused little utility: a tiny markdown-to-HTML bundler that takes plain Markdown documents and wraps them in a built-in CSS theme so they actually look presentable in a browser. No frameworks, no static site generators, no config files demanding tribute — just a straight pipeline from .md to a styled .html file you can open, share, or drop on a server.

What makes this interesting is the niche it carves out. The Markdown ecosystem is dominated by either heavyweight static site generators (Hugo, Jekyll, Eleventy) or raw conversion tools (pandoc, marked) that hand you unstyled HTML and shrug. There's a real gap for the in-between case: "I have a README, a design doc, or a quick writeup — I want it to look nice without spinning up a build pipeline." A bundler that ships sensible default styling solves a problem most of us have hacked around with copy-pasted CSS for years.

Who would benefit?

• Engineers who write internal docs in Markdown and need to share them outside of GitHub or Notion without hosting overhead.
• Technical writers drafting standalone documents — proposals, RFCs, postmortems — that need to look polished as a single HTML file.
• Hobbyists and bloggers who want a one-shot publish workflow without committing to a full SSG ecosystem.
• Tool builders who could embed it as a rendering step in larger pipelines (CLI doc generators, email previews, report builders).

The "bundler" framing is a nice touch — it implies the CSS is inlined or packaged so the output is self-contained and portable, which is exactly the property you want for sharing files via email, Slack, or a cheap static host. Zero stars feels unfair for something this practical; small, single-purpose tools that respect your time deserve more love than yet another React boilerplate.
