Choose up to 20 robots — by name or by slug, the last part of a robot page's address — and change categories. Bookmark this selection or subscribe to its RSS feed in your feed reader. For security, the key in each RSS link rotates every week, so come back here weekly for a fresh link. Removing the feed in your reader stops the subscription.

The RSS key rotates every week: this feed link works until 6 Nov 2026, 00:00 UTC. After that your feed reader shows a notice linking back here, where the new link is waiting — replace the old one with it.
Changes since snapshot tracking began come from recorded snapshots; earlier ones come from approved updates, with before and after values as recorded there. Shows at most 100 events from the latest 101 snapshots per robot and latest 1,000 selected-robot approvals. Older versions remain available in each robot's paginated history. A catalogue change is not automatically a verified improvement.

Watch follows up to 20 of the 222 robots in the index and reports what changes in them — evidence, deployments, specs, price, availability and tests — as a page, an RSS feed or JSON. It records that a value changed and where the new value came from; it does not judge whether the change is an improvement.
