Will my Magento extensions still work after Hyvä migration?

Some yes, some need work. Hyvä needs a compat module for each Luma extension to render frontend HTML. Three outcomes per extension:

1. Vendor ships Hyvä compat, install, done. (Mageplaza, Amasty, Magefan, Mirasvit usually fall here.)
2. Community compat module exists, install + test.
3. Custom bridge needed, I rebuild the frontend layer (Tailwind + Alpine partial).

The pre-project audit catalogues every extension on your store and tells you which bucket it’s in. You see the full report before any work starts, no surprises mid-build.
