A form with spam protection
An invisible check keeps bots out of your responses, your Slack and your inbox. Real people never solve a puzzle.
- No CAPTCHA puzzles
- On by default
- Free on every plan
Free forever, no credit card.
- Create a form. Spam protection is already on.
- Publish and share it. Bots are stopped before a response is saved.
- Your responses stay clean, and so do the sheets, Notion pages and Slack messages they feed.
Without it, bots find a form on the open web quickly: fake sign-ups fill your list, and every email the form sends to an address someone typed in is one a bot can aim at a stranger.
Invisible to real people
The check is Cloudflare Turnstile. It runs in the background while someone fills in the form: no puzzles, no picking out traffic lights. Most people never see it at all.
Always on where it matters most
On forms that bots look for, the check stays on and can’t be switched off: when a workflow emails the respondent through the built-in Nextforms sender, when an Email question asks respondents to verify their address, and when an Address question suggests addresses as people type. The settings page says which one applies.
On every other form you can turn it off in the form’s settings, for the rare audience where a background check gets in the way.
Before answers are saved, too
With unfinished responses on (Pro), the same check runs before the first answers are saved, so bots don’t fill your In progress list either.
