Comparison Overview

#1. Heyflow

Heyflow gives ad agencies a conversion engine and white-label client portal in one platform. The Agency Portal lets you run unlimited campaigns per client, separate responses into clean tabs, and manage everything under your own branding and domain. Native server-side tracking (Meta CAPI, Google Ads, TikTok, LinkedIn, Bing) means conversion data flows back to ad platforms server-to-server — no GTM setup, no developer ticket.

Typeform is a conversational form builder that presents one question at a time. It creates a guided experience for lead capture, quizzes, and surveys, with strong branching logic and CRM routing.

FAQs

What features should I look for in form creation software for my ad agency?

Prioritize: server-side tracking (CAPI) for accurate attribution, lead validation (phone/email verification) to cut junk leads, conditional logic for qualification, CRM integrations for clean handoff, A/B testing for optimization, and multi-client management for scale.

What is the difference between a form builder and a form creation platform?

A form builder creates and shares forms. A form creation platform adds conditional logic, CRM routing, analytics, A/B testing, lead validation, compliance controls, and multi-client management — everything around the form that makes it useful in a campaign workflow.

Which form creation software is best for performance marketers?

Heyflow. It provides native server-side tracking (Meta CAPI, Google Ads, TikTok, LinkedIn, Bing), phone-level lead validation (HLR + SMS OTP), A/B testing with statistical significance, hidden fields for UTM passthrough, conditional logic for in-flow qualification, and native CRM routing to HubSpot, Salesforce, and Pipedrive. No other form builder on this list offers native CAPI.
