So I built a complete, production-ready starter kit that includes everything you need to launch an AI-powered SaaS in days, not weeks.</p> <h2> What's Inside </h2> <p><strong>Next.js 15 (App Router + Server Actions)</strong><br> The latest and greatest from the React ecosystem. App Router for nested layouts, Server Actions for form handling, React Server Components for optimal performance.</p> <p><strong>Authentication with JWT</strong><br> HttpOnly cookies, bcrypt password hashing, login/signup flows, protected routes — all built in and ready to customize.</p> <p><strong>Stripe Subscriptions</strong><br> Monthly and yearly billing with Stripe Checkout. Webhooks for subscription status changes, automatic upgrades/downgrades. Also handles one-time purchases.</p> <p><strong>OpenAI Streaming Integration</strong><br> Chat with streaming responses, credit-based usage limits so you don't get surprise bills. Swap in any OpenAI-compatible API (Azure, Ollama, etc.).</p> <p><strong>Admin Dashboard</strong><br> User management, usage analytics, content moderation — everything you need to run your SaaS.</p> <p><strong>SQLite Database</strong><br> Zero config, no external database needed. Perfect for getting started. Swap to PostgreSQL when you scale.</p> <p><strong>Docker + One-Click Deploy</strong><br> Containerized for development and production. Deploy to Vercel with a single click.</p> <h2> The Tech Stack </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Layer</th> <th>Technology</th> </tr> </thead> <tbody> <tr> <td>Framework</td> <td>Next.js 15 (App Router)</td> </tr> <tr> <td>Auth</td> <td>JWT (httpOnly cookies)</td> </tr> <tr> <td>Database</td> <td>SQLite (via better-sqlite3)</td> </tr> <tr> <td>Payments</td> <td>Stripe (subscriptions + webhooks)</td> </tr> <tr> <td>AI</td> <td>OpenAI streaming + credit limits</td> </tr> <tr> <td>Styling</td> <td>Tailwind CSS</td> </tr> <tr> <td>Deployment</td> <td>Docker / Vercel</td> </tr> </tbody> </table></div> <h2> Why I Built It </h2> <p>Every time I started a new SaaS project, I spent the first 2-3 weeks on the same boilerplate: auth, database setup, payment integration, admin panel. It's tedious, error-prone, and doesn't add any unique value to your product.</p> <p>This kit encodes all those patterns so you can jump straight to what makes your product special — the AI features, the UX, the marketing.</p> <h2> Who Is This For? </h2> <ul> <li> <strong>Indie hackers</strong> who want to ship fast</li> <li> <strong>Agencies</strong> building custom SaaS for clients</li> <li> <strong>Developers</strong> launching their first paid product</li> <li> <strong>Non-technical founders</strong> who want a ready-to-deploy solution</li> </ul> <h2> Get It Here </h2> <p>The full source code, documentation, and commercial license are available here: <a href="https://cyruliks.gumroad.com/l/ghhvqh" rel="noopener noreferrer">AI SaaS Starter Kit</a></p> <p>$997 one-time.
