Key Differences
Site Architecture
Silex: Generates static output while still supporting dynamic, data-driven content pulled from connected sources.
WordPress: Is a dynamic, database-driven CMS that renders pages via themes and plugins on each request.
Static output can be faster and cheaper to host, while a dynamic CMS offers more built-in interactivity without extra configuration.
Pricing
Silex: 100% free and open source under the AGPL license, with no paid tiers at all, funded by donations.
WordPress: Core software is free under the GPL, but hosting, domains, and premium themes or plugins are separate costs.
Silex has no paid tier to budget for, while WordPress's total cost depends on the hosting and extensions chosen.
Governance & Development Pace
Silex: Maintained by Silex Labs, a nonprofit, funded by donations, which its own listed cons note can mean slower feature development than VC-backed competitors.
WordPress: Backed by a large community, extensive documentation, and a huge developer talent pool actively maintaining core software.
Affects how quickly bugs get fixed and new features ship.
Ecosystem Size
Silex: Has a smaller plugin/integration ecosystem than commercial alternatives like Webflow, per its own listed cons, though it connects to WordPress, Strapi, Supabase, and Squidex as CMS backends.
WordPress: Has tens of thousands of plugins and themes.
A bigger ecosystem means more out-of-the-box features without custom development work.
Code Access & Lock-In
Silex: Built on open web standards with no vendor lock-in and direct access to underlying HTML/CSS while editing visually.
WordPress: Also open source and self-hosted with no vendor lock-in, though functionality is more plugin- and theme-dependent than raw markup editing.
Both avoid proprietary lock-in, but Silex emphasizes direct standard-markup editing as a core design principle.
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.

Use Cases
Choose Silex: Individuals or small teams wanting a fully free (donation-funded, no paid tiers) visual builder that outputs SEO-optimized static HTML/CSS with no vendor lock-in, especially if they want to pull data from Supabase, Strapi, or GraphQL APIs.
Choose WordPress: Anyone needing a dynamic, database-driven site with structured content types, user roles, multisite support, and access to WordPress's tens of thousands of plugins and themes, including e-commerce via WooCommerce.
