Site status and catalogue coverage
This page reports what the catalogue holds at this moment, taken live from the database that serves every product page. It is the human-readable version of the machine-readable endpoint /api/health.

Last build
This site was built on 20261016221342
(build tag 20261016221342). Every deploy changes the
tag, which also invalidates the page caches — so the tag you read here is the version you are
actually looking at.
For machines: the same numbers as JSON
/api/health returns exactly these counts, plus the build tag, as JSON.
It is the endpoint our own monitoring, the sitemap builder and the daily self-check read. It answers
200 with cache-control: no-store — never a cached
copy. Opening it in a browser shows a readable page instead of raw JSON (the same URL, chosen by the
Accept header); a script that asks for JSON still gets JSON.
If a number looks wrong
A count that contradicts what you can see on the catalogue pages is a defect worth reporting: write to technical@rssechem.com with the figure and the date you read it. Entries are added in batches, so the published count moves in steps rather than smoothly.
