Why a starter kit

Skip 120+ hours of boilerplate

Every feature is production-tested and ready to customize. Here's what you're not building from scratch.

~20h

Authentication

JWT with refresh tokens, Google OAuth, password reset, email verification, and permission system.

~25h

Stripe Billing

Subscriptions or credit packs, webhook handling, payment receipts, and customer portal integration.

~20h

Multi-Tenancy

Organizations with Owner/Admin/Member roles, team invitations with expiry, and scoped data access.

~10h

Email System

Switchable Mailgun/SendGrid providers, transactional templates, welcome emails, and purchase receipts.

~15h

Test Suite

91 tests with pytest and factory-boy covering auth, billing, organizations, invitations, and more.

~15h

Docker & Deployment

Docker Compose for dev and production, CI/CD workflows, and deployment guides for VPS and cloud.

Built with

Django 5 PostgreSQL Redis Celery Stripe Docker pytest

What's inside

Production code. Not a tutorial.

Real patterns from shipped products. Webhook handlers, atomic billing, role-based access — the stuff tutorials skip.

Built for AI Products

Ship AI-powered APIs on day one

The AI SaaS Kit is purpose-built for deploying AI-powered products. Credit billing, async job processing, and API key auth — the infrastructure your AI startup needs.

Credit-based billing

Atomic deduction with F() expressions. Users buy credit packs, spend them on API calls.

Async job processing

Celery + Redis for long-running AI inference. Submit, poll, retrieve results.

API key authentication

Machine-to-machine auth for programmatic access. Per-org request logging and analytics.

Two kits

Pick your billing model.

Charging monthly? Go subscription. Charging per API call? Go credits. Not sure? Get both.

Subscriptions

Monthly/annual plans, the classic SaaS model.

✓ Org invitations with expiry
✓ Email verification + password reset

Best for SaaS dashboards, team tools, CRM

Frequently asked questions.

What do I get after purchase?
A download button appears immediately on the confirmation page. You also get an email with a download link valid for 24 hours and up to 5 downloads. The download is a ZIP file containing the full source code, ready to clone and run.
What’s the license?
Personal and commercial use. Build and ship as many products as you want with it. The only restriction: you can’t resell or redistribute the starter kit source code itself.
Do I need to know Django?
Basic Python and Django knowledge is helpful, but each kit includes a comprehensive README with step-by-step setup, environment variable reference, and deployment guides for Render and Railway.
Which kit should I choose?
Charging a monthly or annual fee? Go with the SaaS Starter Kit. Building an AI API where users pay per request? The AI SaaS Kit. Not sure? The bundle includes both and saves you $98.
Do you offer refunds?
Yes, within 14 days of purchase if the product doesn’t work as described or our support team can’t resolve a technical issue. Email hello@mail.starterkit4u.com with your order details and the specific issue. We’ll work to fix it first — if we can’t, you get a full refund.
Will I get updates?
You get the current version of the source code. It’s yours to modify and maintain. Major updates may be available at a discounted rate for existing buyers.

Every day on boilerplate
is a day you're not shipping.

Get the foundation. Build what matters. Your first users won't care about your auth system — they'll care about your product.
