NitroPack lets you choose between 5 optimization modes from the “Settings” menu. You can experiment with them and see which one suits you best.

Important Note: After switching between modes, save your settings and purge your cache from the Dashboard so NitroPack re-optimizes your site's pages. The changes will take effect after the new optimizations are done.

These are our two most stable but least powerful modes.

They implement multiple speed optimization methods that improve your website’s performance without being too aggressive.

Both modes use built-in browser techniques for loading resources, instead of our custom coded mechanism. This makes them very safe, at the expense of page speed.

The Strong mode is faster and more aggressive than the previous two.

It uses advanced features like automatic image lazy loading, font definition modification and a special resource loading mechanism.

The Strong mode strikes a great balance between stability and website speed.

While it does load resources differently, the Strong mode doesn’t delay resources automatically. That’s why it usually doesn’t produce the highest-possible page speed scores.

This is our most aggressive and best-performing mode.

It delays JS scripts and prioritizes HTML and CSS to achieve the highest-possible page speed scores.

The Ludicrous mode can be suboptimal for some JavaScript-heavy websites. We have an entire article on why that is. You can check it out here. But these cases are the exception, not the rule.

If you’re using one of our other modes, test Ludicrous on a few pages. Here’s how you can do that in 5 minutes.

This mode allows you to freely tweak NitroPack's settings and customize them to your liking.

Before doing that, there are some specifics to the Custom mode you need to know.

If you change a single setting while using one of the pre-configured modes, you'll be automatically switched to Custom mode.

Each mode includes a specific number of optimization settings to provide you with the best possible performance and stability.

Enabling more than the predefined number of settings for the particular mode, or disabling any of them, shows your intent to fine-tune how NitroPack operates on your site. Hence, you will be automatically switched to the Custom mode.

We’ve arrived at the default NitroPack setup through tons of testing and iterations. Our current settings ensure stability for all users, regardless of their technical expertise.

If you don’t have a specific reason for changing this default setup, you shouldn’t use the Custom mode.
