As a backend developer, I have spent a significant portion of my career setting up the same foundations: secure login, registration, organization management, AI gateway and API structures. Every time I had a new idea or wanted to launch a project with my agency, I felt the friction of those first forty hours of coding.
I wanted to create value and impact people through software, but I was constantly slowed down by a lack of a truly fast, professional process. I realized that if I was feeling this frustration, other developers in the same position probably were too.
That is why I built fast-dj.
Filling the gap in the Django ecosystem
When looking at the current landscape of boilerplates, I noticed two major things missing.
First, while there are many great foundations out there, very few are built from the ground up to handle the current AI wave. Most developers are still manually stitching together OpenAI proxies and tracking tokens in a way that feels like an afterthought.
Second, for those of us working in markets like LATAM, the pricing of existing "professional" boilerplates is often out of reach or doesn't account for our local payment realities. I wanted to build something that offers a complete, high-tier system—the kind of architecture used by top silicon valley startups—at a price point that makes sense for developers who want to scale without breaking the bank.
What is under the hood
The goal of fast-dj is to provide a "production-ready" state on day one. Here is how it handles the heavy lifting:
Advanced Multi-tenancy: It is built for SaaS. You get full data isolation between organizations, RBAC (Role-Based Access Control) with Owner, Admin, and Member roles, and the ability for users to switch between multiple teams seamlessly.
The AI Gateway: Instead of just calling an API, fast-dj includes a unified proxy for major providers. It supports streaming responses via Server-Sent Events (SSE) and, most importantly, precise token tracking and spending limits so you never get a surprise bill.
Hybrid Billing: This was a priority for me. It integrates Stripe for traditional subscriptions and metered billing, but it also includes Mercado Pago for "Credit Packs." This is a game-changer for markets where prepaid models are preferred.
Developer Experience: It comes with a built-in debug dashboard (using Django Orbit) for real-time inspection, a clean Makefile for local development, and extensive documentation to get you from zero to deployed.
Building for impact
I believe that the ability to ship fast is what separates successful projects from those that stay in a folder on your desktop. By automating the "boring" parts—auth, multi-tenancy, and billing—we can focus on the actual value: the AI implementation and the user experience.
If you are a Django developer looking to launch a professional SaaS this year, fast-dj is designed to be your head start. It’s the result of my own need for a faster process, refined into a tool that I hope will help others build their own multi-million dollar ideas.
