If your team prefers everything inside Git Markdown, versioning, PR reviews, CI/CD Docusaurus is still one of the most dependable options. It does require setup and a bit of discipline, but when it’s configured properly, it’s incredibly powerful. I tend to recommend it for engineering-heavy teams that already live in GitHub.

pattern-craft
Professional-grade background patterns and gradients for your websites and apps. Easily copy and paste into your next project. Crafted with modern CSS and Tailwind for seamless integration.
They've reached the free plan limits for server function calls, but, why are function calls needed for a website of this kind? Looking through it, all of the content is static, there's no auth, and in fact, the entire list of patterns is stored in a single typescript file. Seems like there isn't a valid reason to use a server, using Next.js was the default way and they just went with it. Had they used Vite or Next.js's static export, they could've hosted their website for free in a static hosting site like Github Pages or Cloudflare Pages.

BundleMon

- Project mention: Engage Users Instantly: Embed an Interactive Demo in your React SPA | dev.to | 2025-01-09
Wanna is mobile-first, so I chose to render the demo inside a phone frame. I used devices.css because it offers the devices I thought looked best (i.e. minimal bezel to maximize demo space). But for simplicity, here we'll use a library that supports React out-of-the-box: react-device-frameset.
