FAQ
What do I need to provide to get started?
Just your idea and any references you like. If you have a logo/brand, great. Domain and hosting can be yours or I'll guide you through setting them up (most projects deploy free on Vercel).
Can you connect my app to payments, email, or other services?
Yes - Stripe payments, email (Resend/SendGrid), analytics, CRMs, WhatsApp, and custom APIs. Tell me what you need and I'll confirm it in a custom offer if it's beyond the package.
Will I be able to edit content myself?
If you need self-service editing, I can integrate a CMS (Payload, Sanity) or build a simple admin panel - available in Standard and Premium.
Do you provide hosting and deployment?
Yes, deployment is included (Vercel or your own server with Docker). You keep full ownership of the code and all accounts.
My project doesn't fit these packages - what do I do?
Message me! I'll review your requirements and send a custom offer with an exact price and timeline, usually within a few hours.
