FAQ
Do I need to provide my own AI API keys?
Yes, you will need your own API key (OpenAI, Anthropic Claude, or Groq) so the app runs directly under your usage limits and account. I can guide you step-by-step on how to generate one in under 2 minutes!
Will I need to pay for hosting or database fees?
No to start! We will use the free tiers of Vercel (hosting) and Supabase (database), which are generous enough for thousands of users. You only upgrade if your web app scales significantly.
Do I own the full source code after delivery?
Yes, 100%! Upon completion, I will transfer the full source code to your GitHub repository and connect it to your live Vercel account. You hold full IP rights.
Can you customize the app's calculations and AI prompts for my specific niche?
Absolutely! Whether you need a SaaS spend audit tool, a real estate ROI calculator, or an automated fitness planner, I can fully customize the backend logic, scoring system, and AI prompt template to fit your exact business goals.
What happens if I find a bug after delivery?
I offer post-delivery support to fix any technical issues or bugs related to the agreed-upon scope of work, ensuring your app runs smoothly live in production.
