❓ Frequently Asked Questions
Is the SaaS boilerplate really free?
Yes — completely free, MIT-licensed. No credit card, no signup, no strings attached. Download and use it for any project, commercial or personal. There's an optional Pro tier (€49 one-time) if you want priority support and a year of updates.
What tech stack does it use?
FastAPI (Python), Jinja2 templates, bcrypt for auth, xpub-based BTC/LTC payments, JSON flat-file storage (easily upgradeable to Postgres), and systemd + nginx for deployment. The CSS uses CSS variables with a dark theme and Inter font.
How long does it take to get running?
About 5-10 minutes from download to live. Unzip, run pip install -r requirements.txt, execute python3 main.py, and your app is running on port 8766. The included deploy configs make production setup straightforward.
Can I customize the design?
Absolutely. Pick from 5 accent colors when generating, or edit static/style.css after download. The CSS uses CSS custom properties (variables) so changing the entire color scheme is just a few lines. All templates are clean Jinja2 HTML.
Is the crypto checkout secure?
Yes. The checkout uses xpub (extended public key) — your private keys never touch the server. Addresses are derived deterministically and payments are verified via public blockchain APIs (Blockstream/Blockchair). No hot wallet risk.
What's the difference between this and other SaaS boilerplates?
Most SaaS boilerplates cost $50-300 and lock you into specific stacks (Next.js, Supabase, etc.). Ours is free, built on fast, lightweight Python (FastAPI), and includes native crypto payments — not Stripe-dependent. It's also MIT-licensed so you truly own your code.
