Add Spam Protection to React Forms

Building a contact form in React is straightforward. Keeping spam out of it is the hard part. Honeypot fields catch basic bots but miss anything smarter. CAPTCHAs break the user experience — in fact, they can <a href='/blog/real-cost-of-contact-form-spam-for-small-businesses'>cost small businesses more than the spam itself</a>. FormShield gives you a clean alternative: send your form submission to an API, get back a spam verdict, and decide what to do with it — all from your existing React code.

Key Points

1

One fetch call to filter spam

In your form submit handler, POST the message body to the FormShield API. The response tells you whether it is spam or legitimate, along with a confidence score. No SDK, no dependencies.

2

Works with any React setup

Next.js, Remix, Vite, Create React App — it does not matter. FormShield is a REST API, so it works anywhere you can make an HTTP request. Use it client-side or server-side.

3

Real-time verdicts

The API responds in under 200ms. Your users will not notice any delay. Show a success message for clean submissions and silently discard the spam.

4

No user friction

There is no checkbox to click, no puzzle to solve, and no image grid to squint at. Your form looks exactly the same — the spam filtering happens entirely on the backend.
