How I Saved 100+ Hours Building a FastAPI & Stripe SaaS Boilerplate

Source: Dev.to

The Problem

Building a new SaaS project is exciting—until you realize you have to rewrite the same infrastructure code over and over. Between tracking pending boxes, managing expedition reports during an internship, and attending weekend classes, free time is virtually zero. The repetitive setup (database schemas, user authentication, payment gateways) is the #1 reason most developers abandon side projects before they even launch.

The Solution

I decided to fix this problem permanently by creating a production‑ready FastAPI + Stripe SaaS Boilerplate. The goal was a clean, scalable, enterprise‑grade structure that lets developers skip the 100+ hours of infrastructure coding and focus on their core product.

Key Features

• Stripe Integration – Subscriptions, checkout sessions, and secure webhook handling are pre‑configured.
• PostgreSQL & SQLAlchemy – Structured with Alembic migrations for painless database upgrades.
• JWT Authentication – Secure login, registration, and password hashing out of the box.
• 100 % Test Coverage – Core logic is backed by Pytest, ensuring reliability.
