Retrosite: website history visualizer

Retrosite is a local app for making visual timelines from old website captures. Type in a domain or page, and it helps turn the site's Wayback Machine history into a browsable report with screenshots, dates, notes, and source links.

It is built for the kind of web nostalgia and research that usually means opening a dozen archived pages by hand. Retrosite does the tedious part: it finds useful captures, takes screenshots, and lays everything out so you can see how a site changed over the years.

I tried one for youtube:

The reports are editable, so you can clean up labels, pick better screenshots, add notes, and export the final timeline as Markdown or HTML. It works especially well for personal sites, old product pages, blogs, communities, and any corner of the web where the design history is part of the story.

The public demo shows finished timelines, while the local app does the actual generation on your machine. That keeps the archive work private, practical, and easy to revisit whenever you want to explore another site.
