About ShopDigest
The Shopify ecosystem, shown through the work
ShopDigest is an independent directory of Shopify work. Developers, agencies and experts publish the projects they’ve actually shipped — migrations, rebuilds, custom apps, headless storefronts — with the results attached.
For merchants, that means judging a partner on evidence instead of a sales page: browse real builds in your category and budget, then reach out directly. For builders, it means one profile that keeps working after the project ships.
No commissions, no pay-to-rank placements. The best work rises because people save and follow it.
