How OpalSite
compares

Webflow pioneered the visual-first web builder and still does that part beautifully. The problem starts the day you want to leave. Every element, every interaction, every CMS item is locked inside Webflow's proprietary XML. You cannot eject to clean code — you can export a static snapshot, and then you're starting over.

It also has zero AI story. The assumption is still that a human designer drags boxes around by hand. When Claude Code or Cursor writes a site in twenty seconds, pasting it into Webflow to regain a CMS feels like walking backward through a door you already opened.

OpalSite flips the order: your code is the source of truth, the CMS is generated on top, and AI tools write to the same repo the editor reads from. Nothing is proprietary. Nothing is trapped.

Sanity is a developer's content platform, and that's both its superpower and its ceiling. You have to hand-author a schema in code for every content type before anything appears in the studio. For a sprawling marketing site with dozens of one-off sections, that means writing — and maintaining — hundreds of field definitions.

The studio itself is form-based. Clients edit title fields and body fields in rows of inputs, not on the actual page they're publishing. Preview is a separate iframe they have to open. For non-technical clients this consistently causes drift between what they see and what goes live.

And then there's the content lake — your content ultimately lives in Sanity's hosted API. Leaving means writing a migration script. OpalSite auto-detects content from your existing HTML, edits it where it lives, and never asks you to define a schema at all.

WordPress still runs a third of the web, and for good reason — it's free, battle-tested, and has a plugin for everything. That's also the issue. A real WordPress site is a Jenga tower of fifteen plugins, four of which haven't been updated in two years, all fighting over the admin screen.

Security is a constant tax. Every plugin is a new attack surface, and every week brings another CVE. Clients who just wanted to update a headline end up paying their developer to patch Gutenberg, Yoast, and a form builder they barely use.

OpalSite keeps the “anyone can edit” spirit of WordPress but ditches the PHP monolith. Your site is static and fast. Your CMS is a thin editing layer you can turn off at any time. There's no database to harden and no wp-admin to break into.
