Why Silex?

Most no-code tools lock you in: proprietary formats, forced hosting, subscriptions. Silex is different.

• Your data is yours — standard HTML/CSS output, export everything, host anywhere, leave anytime
• Real web skills — everything you learn in Silex (HTML, CSS, JAMstack) is transferable knowledge
• Community-owned — maintained by Silex Labs, a non-profit recognized as being of general interest. No investors, no exit strategy, transparent finances
• Free forever — always free software (AGPL), all features included, no premium tier

"The only open source alternative to Webflow." — "The most powerful and graphically precise website builder that I have experienced."

Who is Silex for?

• WordPress developers — visual frontend, content from WP via GraphQL, ditch the theme layer
• Freelance webdesigners — create client sites without code, export standard HTML, host anywhere
