A modular, multi-tenant SaaS platform for enterprise software
Subscribe, spin up your own organization, and extend it with independently deployable plugins — all on a shared, event-driven core.
Atlas is a subscription-based SaaS platform. Businesses sign up, create their own isolated organization (tenant), and pick the plugins they need — CRM, HR, Inventory, Analytics, and more — instead of buying and maintaining separate point solutions.
- 🏢 Multi-tenant by design — every organization gets isolated data and its own users, roles, and configuration.
- 💳 Subscription-driven — plans unlock which plugins and limits an organization gets access to, with a 14-day free trial on every tier.
- 🧩 Plugin marketplace — enable or disable business modules per organization without redeploying the platform.
- 🛠️ Built for extension — new plugins are built once against the Atlas Framework Layer and become available to every subscribed organization.
Atlas separates enterprise software into five layers, with subscription/tenant management sitting on top of the platform:
┌─────────────────────────────────────────────────────────────┐
│ SaaS Layer (Portal & Subscriptions) │
│ Marketing Site │ Signup & Onboarding │ Platform Admin │
└─────────────────────────────┬───────────────────────────────┘
│
┌─────────────────────────────▼───────────────────────────────┐
│ Business Application Layer (Plugins) │
│ Inventory │ CRM │ HR │ Analytics │ ...more │
└─────────────────────────────┬───────────────────────────────┘
│
┌─────────────────────────────▼───────────────────────────────┐
│ Atlas Framework Layer │
│ @atlas/ui │ forms │ grid │ api │ events │ sdk │
└─────────────────────────────┬───────────────────────────────┘
│
┌─────────────────────────────▼───────────────────────────────┐
│ Core Platform Layer │
│ Auth │ Organizations │ Users │ Plugins │ Audit │
└─────────────────────────────┬───────────────────────────────┘
│
┌─────────────────────────────▼───────────────────────────────┐
│ Infrastructure Layer │
│ PostgreSQL │ Redis │ Docker │ BullMQ │ Nginx │
└─────────────────────────────────────────────────────────────┘
How it fits together:
- A prospective customer subscribes through the SaaS portal, choosing a plan.
- This provisions a new Organization (tenant) with its own isolated data.
- The org's admin enables the plugins included in their plan from the plugin manager.
- Every plugin is built on the shared Atlas Framework Layer, so it looks, feels, and behaves consistently.
- The Core Platform Layer enforces auth, roles/permissions, and auditing across every tenant.

New business modules are built against @atlas/atlas-plugin-sdk and dropped into plugins/. Each plugin ships a manifest.json declaring its id, permissions, routes, and widgets — the backend's Plugin Manager auto-discovers it, registers it, and makes it available for organizations to enable based on their subscription.
