SVG Captcha Protection for the Contact Form
Protect your contact form reliably against spam bots – without external services, without sharing data with third parties, and without relying on Google reCAPTCHA or similar tracking-based solutions.
How it works
The plugin generates a unique captcha image on your own server with every page request. The image is built entirely from vector strokes (SVG) – the solution text is not readable in the page source and cannot be extracted by bots. The solution is stored server-side in the session and automatically validated when the contact form is submitted.
Benefits
- No external services – The captcha is generated entirely on your own server. No data is transmitted to third parties.
- Privacy-friendly – No tracking, no cookies, no connection to Google, hCaptcha, or any other external provider. Ideal for GDPR-compliant stores.
- No build system required – The captcha works even without a compiled Storefront JavaScript bundle. The optional "load new captcha" button is shown automatically after the Storefront build.
- Per sales channel configuration – The captcha can be enabled or disabled individually for each sales channel. Perfect for stores with multiple channels or varying requirements.
- Clean uninstall – When the plugin is removed, all related settings are completely deleted from the database.
Features
- Server-side generated SVG captcha in the contact form
- Characters are drawn as vector strokes – no readable text in the page source

- Case-insensitive input validation

- Fully commented, developer-friendly source code
System requirements
- Shopware 6.7
