Stop form spam with invisible reCAPTCHA
Turn on invisible spam filtering per form. Real respondents see nothing; automated submissions get scored and rejected before they reach your responses.
Included on the free plan — 500 responses/month, no card required.
Setting it up takes about a minute
Open the form's Settings tab
Find the spam protection section and switch reCAPTCHA on for that form.
Publish
Verification runs invisibly on submission — there's no checkbox or image grid for respondents to solve.
Watch your responses
Low-scoring submissions are rejected at the API before storage, so your response list stays clean.
What arrives on the other side
Nothing extra — the point is what doesn't land. Submissions that fail verification are rejected before they become responses or count against your monthly allowance.
What people use it for
- Public contact forms that attract bot traffic
- Giveaway and contest entries where automated entries would skew results
- Any form linked from a high-traffic page
Questions people ask
Do respondents have to solve a puzzle?
No. It's invisible verification — most people never see anything, which is why completion rates don't suffer the way they do with image challenges.
Does spam count against my response limit?
Rejected submissions never become responses, so they don't consume your monthly allowance.
