Same.dev Features
UI Replication
Share the URL to the page you'd like to copy, and it will try to replicate the page structure, styles, and image.

From my experience, it worked quite well with landing pages, when asked to replicate the landing page of Apple TV it successfully did it, even copying images with movie and show covers, preserving hovering states, and many other small details.

But struggled with more complicated pages, for example, when I asked it to copy the Airbnb interface or homepage of our website. It stuck for a few minutes and didn't generate any results in the end, failing to build the projects.

Prompt Editing
Just like in other vibe coding tools, you can send prompts and ask AI to change specific parts of the duplicated page. Just like other vibe-coding tools, it allows you to make changes without knowing how to code.
Export
You can export a folder with the project's code to make edits independently or deploy it to a platform of your choice.
Same.dev Pricing
So far, same.dev hasn't introduced paid plans. You can currently use the app to duplicate as many websites as you want, completely free.
