Will my favorite extension work on Hyvä?

Probably yes — the answer depends on the extension category:

• Storefront-impacting paid extensions (Amasty, Mageplaza, Magefan, etc.): ~95% have native Hyvä support in 2026, or work via the Hyvä Compatibility Module.
• Marketplace storefront extensions (free): ~70% native or compat-supported. Some niche ones may need a port.
• Admin-only extensions (reporting, exports, RMA): 100% — they don’t touch the storefront so Hyvä doesn’t affect them.
• Heavy frontend customisation extensions (page builders, layered nav, configurators): 80 – 90% have Hyvä parity, but check each one before committing.

The audit step in any migration starts with a per-extension compat check — no surprises mid-build.
