What is Silex?
Silex is an open-source website builder for static websites with a visual editor. The project is run by a non-profit organization, has no investors behind it, and is free to use. The output is based on plain HTML and CSS, with no proprietary formats or platform lock-in. Anyone who exports a finished website gets clean, standard code that can be hosted anywhere.
Silex supports integration with headless CMS systems such as WordPress or Strapi. This allows static pages to be combined with dynamic content, without depending on an all-in-one provider.
Core features
- Visual drag-and-drop editor for static websites based on HTML/CSS
- Export to portable, standards-compliant code with no vendor lock-in
- CMS integration with WordPress, Strapi and other headless systems
- Suitable for portfolios, blogs and business websites without programming knowledge
- Self-hostable, fully open source under non-profit stewardship
Who is Silex for?
Freelancers and agencies that build websites for clients repeatedly will benefit most. They retain full control over code and hosting and do not need to factor in licensing fees. Web designers who understand HTML and CSS, or want to learn, will find a tool that puts that knowledge to direct use.
Anyone who needs a finished website in minutes will find Silex is not the right fit. Setup requires some learning. Those who self-host Silex need to be familiar with the associated infrastructure. The visual editor lowers the barrier, but does not replace a basic grounding in web standards.
Context & alternatives
Silex belongs to the category of static website builders with a visual editor. Commercial reference points in this space include Webflow and similar no-code platforms, which offer more convenience and stronger onboarding, but come with subscription costs and platform dependency. Silex reverses that trade-off: less convenience, but no ongoing costs and no lock-in.
The key difference lies in the organizational structure. A non-profit without investors cannot move the project to a paid model or shut it down without a community fork continuing. Anyone planning long-term and prioritizing independence over convenience is starting from a structurally different position than with commercial alternatives.
