OpenStreetMap
Achavi’s main use is analyzing changes in an area between two time periods, but it can also analyze changests.
However, for some reason, that feature is not exposed via a graphical UI and requires tinkering with bookmarklets or urls. The Achavi “about” page claims dragging and dropping a changeset URL would analyze it, but this does not seem to work.
I created a simple helper site. Type a changeset ID or URL, and it will be analyzed with Achavi.

You can use https://overpass-api.de/achavi/?changeset=xxx to analyse a changeset. For the bookmarklet - you don’t drag and drop a changeset url, you just click on the bookmark when on a changeset page, which then opens up the first url I posted.

Hi,
Clicking “help” in Achavi reveals the following: “A single changeset can be visualized by drag & drop of a changeset URL or using a bookmarklet”. Drag and drop does not work. and I wanted something a non tech-savvy user could and which is convenient on mobile. This rules out link editing or bookmarklets.

Drag & drop of a changeset URL works for me with Firefox and Chrome on Ubuntu (but might not work this way on mobile).
Given achavi already open in a separate window and a link to an osm.org changeset, e.g. https://www.openstreetmap.org/changeset/53657054:
It might be useful to also add OSMCha and changeset-map to your page:
