In their own words
Silex
Silex is a visual builder for static websites, with a visual editor, CMS integration, and several publishing choices. It is free and open source under the AGPL license, and can be used as a cloud service, desktop app, or self-hosted setup. The Cloud option publishes through GitLab Pages and supports custom domains and automatic CI/CD builds. Listed CMS and data connections include WordPress, Directus, and Squidex; any GraphQL API can also serve as a CMS or data source. Publishing choices include GitLab Pages, FTP/SFTP, ZIP download, and CapRover. The free GitLab tier has a five-user maximum per private group, 400 CI/CD minutes per month per namespace, and 10 GB total storage. Self-hosted GitLab CE has no user or storage limits, according to the maker, and supports Docker, CapRover, or npx. Silex Desktop is an early-alpha app for Windows, macOS, and Linux; it edits offline, publishes to a local folder, and needs no account. An experimental on-device AI assistant is included in the desktop app, and a local MCP server is listed for AI integration. The maker says sites have no tracking or third-party cookies and user data is not for sale. The listed Cloud and Self-Hosted plans are free, and Desktop is free.
