www.mysitesmanager.com is the easy way to manage multiple WordPress sites. We take the headache out of managing lots of sites by giving you a simple dashboard that lists your sites and any updates that are available. Built for security, we do not store any login data. We do not store your login details or any other passwords or sensitive data. The way the system works is you add our plugin to your site. The plugin creates an xml file that lists any out of date app versions, plugins or themes. Our system reads this xml file and displays the data on your dashboard.
How does the plugin work? 
The plugin will run a daily cron job to check for updates and then write the details to the xml file. We then read this xml file from our system and write the data to your dashboard.
The plugin is not standalone you need a free account with www.mysitesmanager.com to use it.
The plugin is based on code from the WP Updates Notifier plugin (https://wordpress.org/plugins/wp-updates-notifier/) by Scott Cariss but we have substantially modified the code.
Features

DEPRECATED: As of WP v5.5 this plugins functionality is included in WP Core and this plugin is not required anymore. If you are running WP v5.5 or greater, you can de-activate and delete/remove this plugin. This plugin will still continue work fine with versions of WordPress less than v5.5.
WordPress will let you install a NEW plugin or theme from a zip file, but it does NOT allow you to upgrade them from a zip file. If you try to upgrade from a zip file, you will get an error message that says “destination already exists” and the upgrade will fail. WordPress will not allow you to upgrade from a zip file.
Update Theme and Plugins from Zip File will allow you to easily upgrade from a zip file, avoiding the “destination already exists” error message.
There is also an option to create a backup copy of the old plugin or theme, in case there is a problem with the new version.
