Does Hyvä work on Adobe Commerce as well as Open Source?

Yes, Hyvä supports both Magento Open Source and Adobe Commerce. Behaviour is identical for the storefront layer. The differences are:

• Adobe Commerce B2B features (Companies, quotes, segment pricing, approval flows, requisition lists, shared catalogs) all work on Hyvä. The B2B sprint week the calculator allocates covers them on both.
• Page Builder content (Adobe Commerce + paid Open Source extension) renders inside the Hyvä Compatibility Module bridge. No porting work, but you don’t get the Hyvä perf gain on Page Builder pages. Worth migrating heavy-traffic Page Builder content to native Hyvä blocks during the migration.
• Adobe Commerce admin / staging features (Content Staging, Customer Segmentation rules at preview time) are unchanged.
• Adobe Commerce Cloud deployment workflow is unchanged. Hyvä builds with the same setup:static-content:deploy pipeline. CI / CD doesn’t need rework.

Cost of the migration is the same whether you’re on Open Source or Adobe Commerce, the calculator output applies to both. The Hyvä licence cost is also the same.

The one extra consideration on Adobe Commerce: your Magento support contract / SLA may need notifying that you’ve adopted Hyvä for the storefront. Adobe support continues to cover the backend regardless.
