OpenSAAS - Software Development, Hosting and Integration

A Modern Framework for Admin-Heavy Applications

OpenSaaS Stack is an open-source framework built on Next.js App Router with automatic access control, AI-safe architecture, and production-ready components. Build secure admin interfaces in minutes, not months.

Built for Modern Development

Security, type-safety, and developer experience are at the core

Access Control First

Automatic access control on all database operations. Operation-level, field-level, and filter-based access with silent failures to prevent information leakage.

AI-Safe Architecture

Built to be easy and safe for AI coding agents. Clear APIs, predictable patterns, and automatic guardrails prevent common security mistakes.

Type-Safe

Full TypeScript support with automatically generated types from your schema. Catch errors at compile time, not runtime.

Prisma-Powered

Built on Prisma for reliable, type-safe database operations. Supports PostgreSQL, MySQL, SQLite, and more.

Fully Composable UI

Choose from 4 levels of abstraction: primitives, fields, standalone components, or complete admin UI. Use what you need.

Production-Ready

Built with Radix UI and shadcn/ui for accessibility. OAuth support, file storage, rich text editing, and more out of the box.

Simple, Declarative API

Define your schema, generate your database, and get a full admin UI

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

export default config({
  db: { provider: 'sqlite', url: 'file:./dev.db' },
  lists: {
    Post: list({
      fields: {
        title: text({ validation: { isRequired: true } }),
        content: text(),
        status: select({
          options: [
            { label: 'Draft', value: 'draft' },
            { label: 'Published', value: 'published' },
          ],
        }),
        author: relationship({ ref: 'User.posts' }),
      },
      access: {
        operation: {
          query: ({ session }) => {
            // Public can see published posts only
            if (!session) return { status: { equals: 'published' } }
            return true
          },
          update: ({ session, item }) => {
            // Only authors can update their own posts
            return session?.userId === item?.authorId
          },
        },
      },
    }),
  },
})
