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

Every user gets their own workspace. Data is automatically scoped to workspaces, ensuring complete isolation between customers.

• Automatic workspace creation on signup
• Workspace-scoped data models
• Session-based workspace context
• Solo users never see workspace UI (invisible until they need teams)

Stripe Billing

Complete billing integration using Stripe's 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

Invite team members to your workspace with role-based access control.

• Admin and Member roles
• Email invitations
• 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
• Password recovery

Modern Stack

• Backend: Python 3.11+, Flask 3.1, SQLAlchemy 2.0
• Frontend: Vue 3, Vuetify 3 (Material Design)
• Database: PostgreSQL (production), SQLite (development)
