Invoiceproof runs on your own machine — the client starts it, so there is no endpoint to ping. 242 installs a week from npm. Last commit 4 Nov 2026.
Validate, parse, fix and render EU e-invoices: XRechnung, ZUGFeRD, Factur-X, Peppol, KSeF.
Today is the operative word: we check Invoiceproof every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
