Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFormGuard stops spam on your Shopify contact form without adding a captcha, so real customers fill it in as usual. Every submission is checked in the visitor's browser for a hidden honeypot field, forms filled too fast, no real typing, repeat submits, and your own blocked keywords and email addresses.
Still getting spam through your Shopify contact form? SEO pitches, sales emails and fake leads flooding your inbox every day? CAPTCHA not stopping it? MUTE works differently — it detects bots through invisible signals and blocks them silently. No reCAPTCHA, no puzzles, no friction for real customers. Enable from your theme settings. No code. Under a minute. 100 blocks a month, free forever. No credit card required.
- Honeypot detection catches bots with invisible form fields
- Time-based filtering blocks instant automated submissions
- Custom keyword blocking for specific words and email addresses
- One-line install. Enable the app embed from your theme editor — no code.
- Never blocks real humans. Only bot signals are targeted, never genuine users.
- Spam block reports delivered automatically to your email.
