Most boilerplates hide their core behind paywalls. We open-sourced the essential stack so you can inspect the quality before spending a single dollar.
FastAPI 0.115+, async SQLAlchemy 2.0 with PostgreSQL, Alembic migrations, and Pydantic v2 schemas.
Next.js 16 App Router, React 19, Tailwind CSS v4, Lucide icons, Sonner toasts, and dynamic theme switching.
End-to-end type safety directly synchronized from backend openapi.json with openapi-fetch.
Multi-stage Dockerfiles for backend and frontend, docker-compose, and passing GitHub Actions workflows.
The PRO edition adds the complex, high-friction modules that take weeks of engineering time to build and test properly.
Native adapters for Anthropic Claude 3.5, OpenAI GPT-4o, and Google Gemini with auto-reconnect, keepalive pings, atomic balance locks, and auto-refunds on provider failures.
Turnkey subscription checkout, customer portal for self-serve invoice/card updates, and cryptographically verified webhook handlers with deduplication tables.
Organizations with custom slugs, seat limit enforcement, 7-day cryptographic email invitations, and owner/admin/member access control.
Create and revoke environment-prefixed API keys (sk_live_... / sk_test_...) with SHA-256 hashing and granular permission scopes.
High-concurrency SQL quota increment locks preventing overages. Structured HTTP 402 Payment Required responses aligned with billing periods.
One-click personal data JSON export (Art. 15/20) and safe account erasure/anonymization (Art. 17) while preserving B2B organization integrations.
Building the infrastructure plumbing of a production SaaS is identical on every project. Calculate what your time is actually worth:
One-time purchase. Full source code. Commercial license.
Great for learning the basics or building a personal hobby app without billing or AI.
Everything you need to launch a production-grade AI micro-SaaS or B2B platform this week.
The moment you pay, the entire repository is yours: source code, tests, commit history. There is nothing to return, so a refund button would be pure theatre. That is precisely why a fully functional free edition exists on GitHub, and why my contact information is on this page. Inspect the code first, ask me anything, and buy only when the decision is obvious.
