I'm a developer and I kept running into the same frustrating problem when delivering work to clients: I'd redesign a website, rework a layout, or overhaul a visual identity - and I had no good way to actually show what changed.

I wanted something where I could upload a full-height before screenshot and a full-height after screenshot - the kind that are 4000-6000px tall - and let the client scroll through both, see exactly what moved, what was added, what was removed. Everything I found either cropped the image, didn't support full-page screenshots, or gave you a basic slider with zero context.

So I built my own using Next.js, Firebase, Clerk and Stripe.

Splice View allows you to:

Upload full-height before & after screenshots (the entire page or design, not just what's visible on screen)

Add numbered annotation boxes directly on the image to call out specific changes

Share a single link with your client - no login required on their end

They scroll through the full comparison and see exactly what changed and where

It works for anything visual - website redesigns, landing page updates, UI mockups, graphic design revisions, app screens. If you deliver visual work to clients, this is for you.

Right now it's desktop-optimized and focused on photo comparisons with annotations. We're still in the beta so you might find bugs. Video recording mode is in the works.

The deal:

You can use the app without restrictions. All I ask in return is honest feedback - what's confusing, what's missing, what would actually make this part of your workflow.

Thank you for the attention!
