Simple, light, easy and no ads

Does exactly what is needed without any extra bloat. Thanks!

Perfect

I checked the code of this plugin before installing it: it does what it says and absolutely nothing else.

It basically just adds the minimum code to enable the auto-updates within WordPress. There is absolutely nothing else in there, which is awesome.

Install this plugin and rest easy it's not bogging down your website like 99% of plugins out there.

Extremely Lightweight and Does What it Says

Let WordPress to automatically update his core, plugins and themes - silently in the background.

This plugin is not for most WordPress users. It will stop WordPress from automatically updating witch is not recommended. The only reason you might need this plugin is if you have modified your WordPress core files and you want WordPress to stop overwriting them with their automatic security updates. Otherwise you should probably just let WordPress auto update.
