ReadyKit: Open-source SaaS boilerplate with multi-tenant workspaces and Stripe b

What it does

ReadyKit is an open-source Python SaaS boilerplate that provides the foundational infrastructure for building software-as-a-service products. It includes multi-tenant workspace management, Stripe or Chargebee billing integration, OAuth and multi-factor authentication, audit logging, role-based access control, and a Vue 3 frontend. The boilerplate is built with Flask, PostgreSQL, Redis, and Vue with Vuetify components.

Who it is for

ReadyKit targets indie developers and small teams who want to launch SaaS products without building infrastructure from scratch. The tool is designed for founders who prefer owning their own stack rather than relying on third-party SaaS platforms. It appeals to builders comfortable with Python and comfortable self-hosting their application.

Pricing

The software is MIT licensed and free to use. The site does not list any commercial pricing tiers or paid support options.

How it stands out

ReadyKit ships as a cloneable GitHub repository rather than a hosted service, giving users full control over their infrastructure and data. It includes workspace scoping out of the box, meaning query isolation for multi-tenant data separation is built into the model layer. The three-minute setup process—clone, configure OAuth and billing credentials, run—lowers the barrier to getting a working SaaS skeleton running locally. Unlike some competitors, it supports multiple billing providers (Stripe and Chargebee) rather than locking users into one payment processor.

What a founder should check

First, examine what competitors offer in this space—whether established boilerplates like Django Cookiecutter SaaS or commercial alternatives like Wasp or Supabase handle the same problems better or with less configuration overhead. Second, verify the switching costs: how tightly coupled is ReadyKit's workspace and billing logic to application-specific code, and how difficult is it to fork or modify core components as product requirements evolve. Third, assess the moat: ReadyKit's value depends on keeping setup simple and the codebase maintainable, but open-source boilerplates risk commoditization as other projects add similar features or as cloud platforms (AWS, Vercel) offer more integrated solutions.
