See your storefront's actual Content Security Policy right on the page — no devtools required.

Why
---

[](#why)

Magento assembles its CSP from several places at once — core defaults, admin config, and rules added by third-party modules via `config.xml` or `csp_whitelist.xml`. Today, the only way to see what actually ends up in the header is to load the page and dig through the network tab by hand, every time you add a script, an iframe, or a third-party integration.

This module surfaces that same information directly on the page: a small icon that opens a panel listing every active directive exactly as Magento assembled it. You can tell in seconds whether the CSP will block something you just added, instead of finding out from a console error later.

Screenshots
-----------

[](#screenshots)

A small padlock icon sits fixed in the corner of the storefront whenever the panel is active:

[![Padlock icon in the bottom-right corner of the storefront](.github/screenshots/padlock-icon.png)](.github/screenshots/padlock-icon.png)

Clicking it opens the panel:

[![CSP Debug modal showing active directives](.github/screenshots/debug-modal.png)](.github/screenshots/debug-modal.png)

On a [Hyvä](https://hyva.io) store, the same panel renders natively in Tailwind CSS and Alpine.js instead — no jQuery/RequireJS modal:

Installation
------------

[](#installation)

```
composer require stacknuts/magento-csp-debug
bin/magento module:enable StackNuts_CspDebug
bin/magento setup:upgrade
```

The module ships a LESS partial, so redeploy static content for your theme afterwards:

```
bin/magento setup:static-content:deploy -f en_US
# or, in a grunt-enabled dev environment:
grunt exec:luma && grunt less:luma
```

### Hyvä compatibility

[](#hyvä-compatibility)

If a [Hyvä](https://hyva.io) theme is active, the module automatically swaps in a Hyvä-native version of the panel — same data, rebuilt with Tailwind CSS and a native `` + Alpine.js modal, no extra configuration needed. This is wired through Hyvä's own `hyva_`layout-handle convention, so it has zero effect on Luma installs and needs no separate compatibility module.

Enabling it
-----------

[](#enabling-it)

**Stores → Configuration → Security → Content Security Policy (CSP) → Debug → Enable CSP debug panel**

The panel needs both of these to be true before it renders: the toggle above is on, and the request already has developer-level access — developer mode, or an IP allow-listed under `dev/restrict/allow_ips`. Leave it enabled in production and it simply stays invisible to everyone else.

Requirements
------------

[](#requirements)

- PHP 8.1 – 8.4
- Magento 2 with `Magento_Csp` (bundled with core since 2.3.5)
- Optional: [`hyva-themes/magento2-theme-module`](https://docs.hyva.io) ^1.5
