When selling presets, LUTs, or Photoshop services, showing before and after images is a great way to show the world what your product or services can do. After being surprised at the difficulty of creating beautiful image sliders, I went ahead and made a SaaS to allow anyone to create high-quality, performant image sliders with just a few clicks.
I built it in just about a week, using Auth0, Next.js, Typescript, Tailwind CSS, React, and Stripe.
Haven't launched the platform... yet.
