Introduction

ReadyKit is a production-ready Flask SaaS template that gives you everything you need to build and ship a multi-tenant SaaS application. Instead of spending weeks setting up authentication, billing, and team management, you can focus on building your actual product.

Built on the Enferno framework, ReadyKit adds the essential SaaS features that every subscription business needs.

Key Features

Multi-Tenant Workspaces

Workspaces group each customer's business data. Protected routes check membership, and workspace query helpers filter records. New features must use both protections; ordinary SQLAlchemy queries are not automatically scoped.

• Automatic workspace creation for new OAuth accounts
• Workspace-scoped data models
• Session-based workspace context
• Non-superadmins with one workspace skip workspace selection

Subscription Billing

Stripe or Chargebee - your choice. Hosted pages, no custom checkout UI to maintain.

• Hosted checkout for upgrades
• Customer portal for subscription management
• Webhook handlers for plan changes
• Free and Pro plan support out of the box

Team Collaboration

Workspace admins create member accounts and assign roles. Email invitations are not implemented yet.

• Admin and Member roles
• Member management UI
• Owner protection (can't be removed or demoted)

Authentication

Comprehensive auth system with modern security features.

• Email/password with Argon2 hashing
• OAuth (Google, GitHub)
• Two-factor authentication (TOTP)
• WebAuthn/Passkeys support

Modern Stack

• Backend: Python 3.11+, Flask 3.1, SQLAlchemy 2.0
• Frontend: Vue 3, Vuetify 3 (Material Design)
• Database: PostgreSQL (production), SQLite (development)
• Sessions: SQLAlchemy by default, Redis with the full setup
• Task Queue: Optional Celery with Redis
• Deployment: Docker Compose ready
