Build sites at the speed of save.

Baybay is a zero-config static-site generator. Markdown in, HTML out, deployed in under a minute — no bundler, no plugins required, no framework lock-in.

Quick start

Four steps from empty folder to live URL.

Why Baybay

Small on purpose. Every feature earns its bytes.

  • zero-config

    Sensible defaults

    A new project builds with no config file at all. Add baybay.config.js only when you need to override something.

  • markdown-first

    Markdown is the source

    CommonMark plus front matter, smart quotes, heading anchors, and footnotes. HTML files pass straight through.

  • < 40 ms

    Incremental rebuilds

    The dev server rebuilds only what changed and hot-swaps the page in place. No full-refresh flicker.

  • i18n built in

    Multilingual by default

    Declare i18n.locales once and Baybay mirrors your routes per locale with automatic hreflang tags.

  • no lock-in

    Plain output

    The build is static HTML, CSS, and your own JS. Move hosts, or stop using Baybay entirely — your site still works.

  • one binary

    Deploys itself

    baybay deploy talks to Netlify, Vercel, GitHub Pages, and plain rsync targets out of the box.
