NitroPack lets you choose between 5 optimization modes from the “Settings” menu.

You can experiment with them and see which one suits you best.

As a rule of thumb, the best mode for your website is the one that produces the highest scores with the least user experience issues.

Now, before you start experimenting, let’s look at each mode in detail.

The Standard and Medium Modes

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

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.

The Ludicrous Mode (Default)

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 very few 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.

The Manual Mode

This mode allows you to tweak the default configuration of some Advanced features, like Resource Minification or Combining Resources.

The Manual mode is designed for tech-savvy users who need to solve complex technical issues. That’s why we strongly recommend that you don’t tweak any of the Advanced features unless it’s absolutely necessary.

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 Manual mode.
