Mindszi Builder
Build your own product experience: your storefront, your app, your portal, on easy APIs, typed SDKs and AI that builds with you.
Mindszi Builder puts the whole platform behind easy APIs and typed SDKs, so the experience your customers get is entirely your own.
Start building in an afternoon
import { Store } from '@mindszi/store-sdk'
const store = new Store({ apiKey })
const plans = await store.plans.list({ region: 'EU' })
Everything the platform can do, you can build on
The same capabilities behind your storefront, your app and your automations, reachable three ways: call the API, use the SDK, or let AI do it.
| Capability | API | SDK | AI |

Add a top-up button to our account page
Done. It lists your real top-up options and calls the typed SDK to buy.

Connect Claude or any MCP client to your tenant and it works with your real catalogue, calls scoped tools and writes code against the typed SDKs.
const plans =
await store.plans.list()
plans.map(plan => (
<PlanCard plan={plan} />
))
