Everything is moving faster in 2026. If you are still building Link-in-bio tools from scratch, you are losing money.

I decided to build LinkSync — a high-performance, SEO-optimized boilerplate that doesn't just show links, but handles bookings directly. Here is how I built it and why I’m open-sourcing the core UI.

🛠 The Modern Stack
To make it lightning-fast, I used:

  • Next.js 15 (App Router): For better SEO and instant page loads.
  • Tailwind CSS 4: For the cleanest, most maintainable styling.
  • TypeScript: Because we want zero bugs in production.

✨ The "Secret Sauce"
Most Link-in-bio tools are just a list of buttons. LinkSync is different. It includes:

  1. Modular Components: Easily swappable link buttons and social icons.
  2. Mobile-First Design: It looks like a native app on Instagram and TikTok browsers.
  3. Pro Booking Flow: A 3-step calendar system that actually converts visitors into clients.

🎁 Get the Lite Version (Free)
I believe in giving back to the community. You can grab the entire UI Lite version for free on my GitHub. Start your project today without spending a dime on the interface.
