Developers

Real code.
Governed runtime.

Relpin apps are real TypeScript or Python projects with a governed SDK. This page is the honest state of the developer surface: what is live, what is being written, and what is planned.

SDK & Libraries Live

Two runtimes.
One governed SDK surface.

TanStack Start / React / TypeScript projects and a Python / FastAPI runtime with table helpers. Both author in Studio, both deploy through pinned releases, both query server-side.

Component Library Live

shadcn/ui-style components.
Shipped with every template.

App templates include workspace UI packages — tables, forms, sheets, and charts built on the same primitives as this site. Components live in your project: inspect, extend, or replace them.

Surface Status

The rest of the surface.
Stated plainly.

We publish the state of every developer surface instead of pretending it all exists. This board is updated as the beta progresses.

Surface Status
Documentation Live Public docs now cover the app lifecycle, SDKs, OpenCode, data access, and beta limits.
API Reference Planned No public platform API yet. Studio includes an interactive runner for your app’s own endpoints.
Self-Hosting Planned Managed cloud only during beta — EU data residency (Frankfurt). Dedicated isolation on request.
Status Page Planned No public status page yet. Incidents are communicated directly during beta.
Honest surface map · Updated during beta
Developers

Read code.
Not promises.

The fastest way to evaluate the SDK is inside Studio — every template is a real project you can open and edit.
