Fayz Dev Center

Build working products with the Fayz SDK

From zero to a live app — plugins, Supabase, deploy.

Quickstart · 5 min See the full tutorial

Start here

From npm install to an app running on mock data, in five minutes.

Fayz app (the defineSaas shell) or Fayz Headless — pick yours.

The 7-step journey, from the first command to going live.

Build

Build your own plugins

Create your plugin in the incubator and follow the contract manifest.

Data with Supabase

The data model, fayz db apply and multi-tenant RLS.

Brand tokens, dark mode and surface customization.

Made for agents

Your app as a data layer

Every app is born agent-ready: the aiTools contract, typed and permission-scoped.

Connect your agent

llms.txt, a .md per page and the scaffold's AGENTS.md — the map your agent reads.

Connectors and channels

The connector spine, Google Calendar/Stripe and the WhatsApp roadmap.

Reference

Every SDK plugin with its status, capability and version.

Every fayz command, with flags and the env contract.
