What is the Hyvä Compatibility Module, what does it cover?

The Hyvä Compatibility Module is a separately-licensed wrapper that lets Luma-only extensions render their UI inside a Hyvä storefront without rewriting them. It does this by injecting a sandboxed Knockout/RequireJS environment for those specific extensions, while the rest of the page stays Hyvä-native.

What it covers:

• ~95% of paid Luma-only extensions from major vendors (Amasty, Mageplaza, Magefan, Aheadworks, etc.)
• Most Magento Marketplace storefront extensions that haven’t shipped native Hyvä support yet
• Custom Luma extensions written in-house (with some setup work)

What it doesn’t cover:

• Page-builder extensions that try to take over the whole page rendering pipeline
• Extensions that hard-code Luma-specific class names everywhere
• The performance wins, Compat Module re-introduces some Luma JS, so a Compat-heavy store loses 10-30% of the Hyvä perf win. Still way ahead of pure Luma.
