SaaS Boilerplate - Open Source and free SaaS stack that lets you build SaaS products faster in React, Django and AWS. Focus on essential business logic instead of coding repeatable features!
A full-stack SaaS starter from a Polish dev shop (Apptension) built on React 19 + Django 5 + AWS CDK. It gives you auth, Stripe subscriptions, multi-tenancy, RBAC, real-time notifications, and a CRUD scaffolding generator out of the box. Aimed at developers who want to skip the boilerplate and own the infrastructure rather than pay for a platform like Render or Railway.
The multi-tenancy implementation is genuinely complete — RBAC with custom roles, SCIM 2.0 directory sync, SAML/OIDC SSO, and per-tenant encrypted backups with restore conflict handling; that's not something most boilerplates touch. The AWS CDK infrastructure is first-class code, not a pile of console screenshots — you get real multi-environment deployments (QA, prod) with a proper CI pipeline. The Cursor rules directory ships with the repo, which means the coding conventions are machine-enforceable, not just a wiki page. The CRUD generator (Plop-based) that produces GraphQL operations, forms, and tables from a single command is a real time saver once you're past the learning curve.
The stack is opinionated to the point of being a lock-in bet: React + Django + AWS CDK with GraphQL (Apollo + Graphene) means you're carrying four distinct ecosystems with their own upgrade cycles — the Graphene Django library in particular has historically lagged Django releases. Windows is explicitly second-class (WSL2 required, not optional), which will irritate some teams. The AI integration is OpenAI-only with no abstraction layer, so swapping providers means touching the integration code directly. At ~2900 stars and backed by a single agency's roadmap, the governance risk is real — if Apptension's priorities shift, maintainers thin out fast, and you're left holding a large custom codebase.
