# Requirements & Compatibility

Requirements

* ExpressionEngine 6.4 or greater
* PHP 8.2 or greater
* PHP `max_input_vars` set to a minimum of `2000`.

{% hint style="info" %}
Sites using a lot of bloqs and custom fields within an entry may want to consider increasing PHP's `max_input_vars` setting. Usually the default is 1000. Increasing it to 2000 or more may be required.
{% endhint %}

{% hint style="info" %}
Bloqs is built using the same concepts as the Grid field, and because Grids within Grids are not allowed, a Grid (and similarly File Grid) may not be placed within a bloq*,* however, you can use our [Simple Grids & Tables](https://boldminded.com/add-ons/simple-grids-tables) add-on for basic Grid functionality within Bloqs.

The native Fluid field type is also not supported by Bloqs.
{% endhint %}

If you are unsure if an add-on works in Bloqs, but it works in Grid, then chances are it already works in Bloqs. There are a vast number of 3rd party fieldtypes not listed above that already work in Bloqs.

If your add-on/fieldtype is compatible with Bloqs and you don't see it in the list above, [send us a message](https://eebloqs.com/contact) and let us know!

### Performance

Bloqs is a robust and powerful add-on that adds a lot of flexibilty when building out your site content. Since you can add any number of bloqs to a single entry, keep in mind that the more bloqs you add, the more template parsing is required, and the longer it may take for a control panel page to load when editing an entry. For example, if you add 10 bloqs to an entry, and if each bloq has 5 atoms in it it, you're effectivley adding 50 custom fields to the entry. To mitigate this on the front-end you can use Bloqs' [built in caching option](/bloqs/docs/configuration/hidden-config-options.md#field-caching), or add full featured caching with [Speedy](/speedy/docs.md). In most cases caching won't be required, just keep performance in mind when planning and building your site with Bloqs.
