Haven

Haven is a self-hosted website builder that combines a static site generator with a friendly, browser-based editor. You write content and manage pages through a clean web interface, and Haven compiles everything into a fast, static site. It is built with Node.js and stores content in a local SQLite database, making it easy to run on a small VPS or even a Raspberry Pi.

Haven supports Markdown for writing, includes a built-in image gallery, and offers customizable themes via Handlebars templates. It generates RSS feeds, sitemaps, and supports custom domains and HTTPS out of the box. The project is fully open source under the GPLv3 license, and you can extend it by writing your own plugins or modifying the source.

This tool is ideal for developers and hobbyists who want full control over their personal website without relying on a hosted platform. Haven is maintained by a small open source community and is available for free. You can find installation guides and documentation on its official website.
