Zero-config markdown blog engine shipped as a family of packages: @yamblog/core handles parsing, typed frontmatter schemas, querying, full-text search, related/adjacent posts, and feed generation, while @yamblog/next, @yamblog/astro, @yamblog/react, and @yamblog/remark adapt it to your framework of choice.
Point it at a directory of .md files and you get a fully typed content API - no database, no CMS, no config. It generates RSS feeds, sitemaps, and llms.txt so both search engines and AI agents can consume your writing.
Dogfooded in production: the blog on this site runs on Yamblog.
