QC Update Laboratory
Test Joomla core and extension updates in a private production-derived laboratory, review evidence, and push the exact tested package to production—free.

Membership Overview
QC Update Laboratory includes its complete update-testing workflow free, with no license key, subscription, paid activation, trial, or paid tier. Create one isolated private laboratory from the current production files and database, capture the exact Joomla core or extension update package, verify its SHA-256 checksum, and install it only in the laboratory first.
Review the private frontend and administrator area alongside automated evidence such as version results, route checks, installer messages, file and database changes, logs, and visible issues. After approval, QCUL can push the exact tested package to production with preflight checks and either your existing recovery method or a temporary QCUL rollback checkpoint. Undo tools are available for the latest laboratory update and, during the protected window, the production push.
