Once a form is active, there are two ways to send people to it.

The direct link

Every form has a public address at itsjustbig.com/f/<slug>. A simple single-page form works even without JavaScript — visitors can fill it out and submit on a slow connection or a stripped-down browser. Forms that use multiple pages or conditional logic step through in the browser, so those need JavaScript.

Shorten it

From the form, click Shorten it → to mint a short link in one click. The short link is tied back to the form (form_id), so its clicks and this form's submissions can be looked at together. See Links for what a short link is and how its stats work.

Anti-spam

Submissions are rate-limited, and forms carry a hidden honeypot field along with basic bot filtering to keep automated noise out. This protects your form from casual spam — it isn't a claim of airtight security.

Because a stored submission counts against your weekly cap, spam that gets past those filters spends the same budget your automations draw on. A real submission is still never refused — every one is stored, on every plan. But once the cap is spent, the responses that arrive after it are stored locked: you see that they came in, not what they say, until they unlock at the weekly reset. Junk traffic can therefore lock up the genuine leads behind it and, because the released backlog is served before your automations, keep those automations quiet into the following week too. If a public form starts drawing junk traffic, check your usage on Settings → Billing.

Branding

On the free (teeny) plan, public forms show a small "Powered by big." footer. Paid plans don't show it.

There's no embed or iframe support for forms, and no QR code generation — both are unavailable today, share the direct link or the short link instead.
