Show HN: Deepswapp Browser: browser the browser with another browser

A "deepswapp" of a website has data from one website in a layout of another website. Deepswapp Browser allows users to seamlessly browse this alternative version of the Internet, today.

The whole Web can look like Wikipedia, old Reddit, or your own website. Once deepswapped, the website transformation is reusable without AI.

    Single-file HTML page
    Only essential data rendered
    Synchronized tabs
    Synchronized scrolling
    No backgrounds
    No animations
    Data auto-refresh
    Image lazy loading

This desktop app works on every platform (Docker images also available) and opens a separate Chrome instance, which mirrors opened tabs in the user's main browser. Several deepswapps are included with the download, so no AI subscription is needed for a test drive. A fresh deepswapp takes around 10 minutes and costs about $0.40c on deepseek-v4.1-flash. This goes down by half when deepswapping a known website.

Tech side: fully in Golang, with AI-generated JavaScript never executing in the user's main browser.

Roadmap: Web and Mobile access, even deeper swaps, parallel swaps.
