Staunch

Staunch is a WordPress plugin designed to prevent automatic updates from running on live production sites. It is ideal for developers and site administrators who want to maintain control over when and how updates are applied, avoiding potential disruptions or version control conflicts.

• Blocks automatic updates on live sites: Prevents admins and superadmins from running automatic upgrades for core, plugins, and themes.
• Simple constant-based control: Add define('CAN_UPDATE', true); to your development site's config file to allow updates there; live sites without this constant remain locked.
• Supports Multisite installations: Works with WordPress Multisite networks, ensuring consistent update control across all sites.
• Enforces best practice workflows: Encourages testing updates on a local or staging environment before deploying to production, reducing risk of breakage.

By using Staunch, you ensure that automatic updates never run unsupervised on your live site.
