I built Lancer Write with a $0 budget.</p> <p>The Tech Stack:</p> <p>Framework: Next.js 15 (App Router)</p> <p>Auth: Clerk (Free tier)</p> <p>Database: Supabase (Free tier)</p> <p>AI: Groq + Llama 3.3 (Zero latency, ultra-cheap)</p> <p>Payments: PayPal Developer SDK</p> <p>The "Aha!" Moment<br> I noticed ghostwriters were struggling with client management. I built a system where the "back door" is automated via webhooks. When a user pays via PayPal, a Supabase webhook triggers, updating their is_pro status instantly.</p> <p>The Killer Feature: Magic Links<br> I bypassed the "Account Fatigue" problem by using secure, unique tokens in URLs. Clients can approve content without ever creating a login.</p> <p>I’m outreaching to some BETA TESTERS who would like to become a part of LancerWrite and get a FOREVER ACCOUNT for JUST $15. For any ghostwriters out there, feel free to reach out any time</p> <p>Take a look at the live build: <a href="https://lancer-write.vercel.app/" rel="noopener noreferrer">https://lancer-write.vercel.app/</a></p> nextjs ai saas webdev
