Gravity Forms Zero Spam

The plugin adds a signed, time-limited token to your form and checks it on submission. Most spam bots post directly to your site without loading the page or running its JavaScript, so they never pick up a token and their submissions are marked as spam.

No CAPTCHAs, no puzzles, no extra fields, no cookies, and nothing to configure to get started.

Filter submissions against a list you control. Useful when spam keeps arriving from one domain, or when a business enquiry form should not accept free consumer addresses.

An optional second opinion on submissions the token check has already judged. Two separate tools, both off until you turn them on:

It runs on WordPress 7.0’s built-in AI connectors, so you connect OpenAI, Anthropic, or Google once and every plugin on the site shares it. Zero Spam never stores API keys, and nothing is sent until you opt in. You can write your own instructions, skip fields that collect sensitive data, and cap how many submissions are reviewed per hour.

If the free Shield Security plugin is active, its silentCAPTCHA bot detection can act as an additional check, globally or per form. Like the token check it runs server-side and stays invisible to visitors, and if Shield is deactivated or returns an error, submissions are never blocked. Contributed by Shield Security developer Paul Goodchild.

Off by default. Turn them on and you get a summary of how many entries were marked as spam, broken down per form.

Zero Spam does not interfere with other spam-blocking plugins, including Gravity Forms’ own honeypot field and reCAPTCHA integration. Honeypots catch simple bots and reCAPTCHA asks real people to click traffic lights; Zero Spam asks nothing of your visitors at all, and you can layer it on top of either rather than replacing them.
