Web Algebra runs on your own machine — the client starts it, so there is no endpoint to ping. 297 installs a week from pypi. Last commit 29 Oct 2026.
Composable Linked Data and SPARQL operations, and LinkedDataHub content tools
Today is the operative word: we check Web Algebra every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
