Silex

Silex is an open-source, self-hosted web app that allows users to visually create static websites. It functions as a visual builder that produces standard HTML and CSS, removing the vendor lock-in associated with proprietary no-code platforms. Users can deploy Silex as a server via Docker or Node.js, use it as a web application, or utilize a desktop app for offline work.

The software is designed for web agencies, freelance designers, and no-code developers who require full CSS control and the ability to host their sites on any provider. By focusing on static output, it aligns with the JAMstack architecture, ensuring that sites remain fast and secure. It is maintained by a non-profit organization and released under the AGPL license, ensuring all features remain free without premium tiers.

Key features

• GrapesJS-based visual editor with drag-and-drop page building
• Static HTML and CSS output for flexible hosting
• CMS integration with WordPress, Strapi, Squidex, and GraphQL APIs
• Compatibility with 11ty for static site generation and CI/CD deployment

The architecture is organized as a monorepo, combining a Node.js server with a frontend editor and a Rust-based server library. It allows developers to bind visual components to dynamic data sources, making it a viable frontend for headless CMS setups. This makes it particularly useful for WordPress developers who want to bypass the theme layer and use GraphQL for content delivery. The system also supports a plugin-config system and shared contracts to maintain consistency across the editor and server components.

Silex is a free and community-owned tool for those seeking a professional visual workflow without subscription fees or proprietary data formats.
