Describe a feature.
Claude Code builds it.

OpenSaaS Stack is a config-first Next.js stack built for AI-assisted development. Tell Claude Code what you want and it ships real features — with security and access‑control baked in.

Quick Start Build with Claude Code

One config, fully secured

Define your data and access rules in opensaas.config.ts. The engine secures every database operation automatically.

opensaas.config.ts

typescript

import { config, list } from '@opensaas/stack-core'
import { text, select, relationship } from '@opensaas/stack-core/fields'

export default config({
  db: { provider: 'sqlite', url: 'file:./dev.db' },
  lists: {
    Post: list({
      fields: {
        title: text({ validation: { isRequired: true } }),
        status: select({
          options: [
            { label: 'Draft', value: 'draft' },
            { label: 'Published', value: 'published' },
          ],
          defaultValue: 'draft',
        }),
        author: relationship({ ref: 'User.posts' }),
      },
      access: {
        operation: {
          // Anonymous visitors only see published posts; an access rule can
          // return a boolean or a Prisma filter that scopes the rows.
          query: ({ session }) => (session ? true : { status: { equals: 'published' } }),
          // Only the author can edit their own post.
          update: ({ session }) => (session ? { authorId: { equals: session.userId } } : false),
        },
      },
    }),
  },
})

From zero to feature in three steps

No boilerplate, no manual wiring. Scaffold, run, and let Claude Code do the building.

Step 1

Scaffold your app

npm create opensaas-app

One command sets up a fully configured OpenSaaS Stack project.

Step 2

Start the dev server

pnpm dev

Your admin UI, database, and access control are wired up out of the box.

Step 3
