Silex is an open-source, visual website builder focused on creating fast static websites while still supporting dynamic data via APIs and CMS integrations. It can be used online or deployed on your own infrastructure, and also allows code-level control when needed.
Key Features
- Drag-and-drop visual editor for building static websites
- Built-in HTML, CSS, and JavaScript editors for advanced customization
- Plugin architecture for extending the editor and adding integrations
- Works well in composable/headless workflows (static front-end with external CMS/API)
- SEO-oriented static output and support for publishing/hosting workflows
Use Cases
- Building marketing sites and landing pages without writing code
- Creating static front-ends backed by a headless CMS or custom APIs
- Web studios producing client sites with a visual workflow and optional code control
Silex is a flexible option for teams and individuals who want a Webflow-like visual experience while keeping output based on web standards and portable static files. Its extensibility and headless-friendly approach make it suitable for modern JAMstack-style deployments.
