One TypeScript SDK. Any backend. Zero rewrites.
February 2026
Build on Salla? Everything is Salla-shaped. Migrate? Rewrite 100% of your integration layer.
Different data shapes, auth flows, price formats, and pagination. No standard exists.
Agencies maintain separate codebases per backend. Costs multiply linearly.
A product is a product. A cart is a cart. An order is an order. The shape differs — the concept doesn't.
| Salla | Medusa | |
|---|---|---|
| Auth | OAuth tokens | JWT + pub key |
| Prices | 10.00 (major) | 1000 (minor) |
| Cart | No cart API | Full CRUD |
| Pagination | page / per_page | offset / limit |
Same composables. Same frontend.
Same test suite. All green.
Map backend APIs to 26 unified types. Salla, Medusa — more coming.
Plug in payments (Tap), email (Resend), analytics (GA), delivery (Armada).
SQLite / Postgres fallback fills adapter gaps automatically. No custom code.
+ 6 more providers on npm
From architecture → adapters → providers → apps → docs → CI/CD → deployment
The Vercel model: open source creates distribution, Cloud creates revenue.
Pay for infrastructure, not for success. Unlimited orders, products, and customers on every plan.
