We support 11 operators covering every common use case:

• Equals / Does not equal — exact string or value match.
• Contains / Does not contain — case-insensitive substring search.
• Greater than / Less than — numeric comparisons (works on number, rating, and linear-scale fields).
• Is empty / Is not empty — checks whether the respondent answered the field at all.
• Is selected — for checkbox arrays, fires when a specific option is checked.
• Matches regex / Does not match regex — full JavaScript-style RegExp for advanced patterns like ^\d{5}$ (US ZIP) or @yourcompany\.com$ (only company emails).

Invalid regex patterns are caught in the builder with a red border and an "Invalid regex" caption — they fail-closed at runtime, so a typo never breaks the form.

Open any form, click the A/B Test button in the toolbar, and Start Experiment. Behind the scenes we:

1. Duplicate the form into Variant A (your original, untouched) and Variant B (your free space to change anything — question wording, element order, theme, even structure).
2. Mark the parent form as an "experiment container" — its public URL stays the same, but it now sticky-routes 50% of visitors to A and 50% to B.
3. Start tracking views, submissions, and conversion rate for each variant independently.

Edit Variant B until you're happy with the alternative. The original Variant A remains your safe baseline.

All 35 fonts are loaded from Google Fonts and available on every plan. Click a font to see its name in its own typeface:

All 70 languages are available on every plan. The native name is shown first, with the English name in parentheses:

We ship 47 native integrations across CRM, project management, marketing, automation, databases, messaging, support, analytics, and scheduling — plus 7 payment processors and 5 tracking pixels. Each one is configured per-form with your own credentials — no shared bottleneck, no middleware layer:

Plus 8,700+ apps reachable through the n8n, Make, and Zapier integrations. All three share the same JSON envelope, so a workflow you build in one platform is one-paste-away from running in another.

Payment processors — accept payments inside any form via a hosted checkout you control:

Tracking pixels & analytics — auto-injected on your published form (or hosted on your own domain) to attribute conversions back to your ad campaigns:

Native (Google Sheets, Slack, HubSpot, Notion, Airtable, etc.): direct, no middleware, no per-task billing, no rate limits on top of the destination's own. Best when the app is on our list.

Zapier / Make / n8n: use these for the long tail of 8,700+ other apps, or when you need branching logic between Fantastic Forms and the destination. You bring your own automation account; we just POST the submission JSON to your webhook.

Model Context Protocol (MCP) is an open standard that lets AI assistants — Claude Desktop, Cursor, Windsurf, Zed, and any other MCP-capable client — read and write data on services you authorize. Our MCP server lives at https://fantasticforms.com/api/mcp and exposes tools to list, read, create, and update your forms in plain language.

Example: connect Claude Desktop

Edit claude_desktop_config.json and add:

{
  "mcpServers": {
    "fantastic-forms": {
      "url": "https://fantasticforms.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ff_live_YOUR_KEY"
      }
    }
  }
}

Restart Claude Desktop. Then you can ask things like "List my draft forms", "Create a 3-question customer survey with a 1-10 rating and a comment box", or "Add an email field to the contact form."

Cursor and other MCP clients use the same URL + Bearer header (settings vary; consult their MCP docs). Pro plan only.

REST API — pull data on demand from any backend (Node, Python, PHP, Go, etc.). Best for syncing forms or submissions into your own product or running scheduled reports.

MCP — give an AI assistant conversational read/write access to your forms. Best for "build me a form" / "fix this question" workflows inside Claude, Cursor, or other AI clients.

Webhooks — react in real-time to incoming submissions. Best for plugging Fantastic Forms into your own server-side automation without polling.
