OnePage.io vs. Heyflow:
Funnels that turn paid clicks into customers
OnePage looks affordable until you add their add-ons, Zapier subscriptions, GTM workarounds, and external A/B testing tools. Heyflow includes it all natively.
Why marketing teams move from OnePage to Heyflow
OnePage is a capable landing page builder, but if you're scaling paid campaigns, you'll hit walls. Tracking drops off beyond Meta. A/B testing doesn't exist. Every CRM except HubSpot requires Zapier. Heyflow gives you native tracking for six ad platforms, built-in A/B testing, and direct CRM connections, no middleware required.
Track Beyond Meta
OnePage has Meta CAPI. So does Heyflow. But Heyflow also ships native tracking for TikTok, Google Ads, LinkedIn, Bing, Taboola, and Outbrain, all code-free. Plus Hotjar, Clarity, and Matomo. If your ad budget goes beyond Facebook, you need tracking that covers every channel.

A/B Test Without Workarounds
OnePage has no A/B testing. You can't test headlines, layouts, or CTAs without bolting on external tools. Heyflow ships native A/B testing with statistical significance and traffic allocation. Test everything, optimize everything, all in one platform.

Six CRMs, No Zapier
OnePage connects natively to HubSpot only, and even that's limited to basic fields. Salesforce, Pipedrive, Zoho, HighLevel, ActiveCampaign? All require Zapier. Heyflow connects natively to all six, plus Personio, Recruitee, and softgarden for recruiting.

We switched from OnePage after our funnels went down and we didn't even get notified. Heyflow's infrastructure is rock-solid, and the native integrations saved us hours of Zapier headaches every week.
Frequently asked questions
Is Heyflow just another form builder?
No. Heyflow is a funnel platform built for performance marketers. While OnePage builds landing pages with forms, Heyflow delivers the full conversion stack: server-side tracking for six ad platforms, native A/B testing, HLR phone validation, and direct CRM integrations without Zapier.
Is Heyflow free?
Heyflow offers a free 14-day trial so you can test all features, no credit card required. OnePage has a lower starting price, but the cost of Zapier subscriptions, external A/B testing tools, and GTM workarounds adds up fast.
View PricingIs Heyflow compliant and secure?
Yes. Heyflow is GDPR compliant with EU servers, SOC 2 Type II certified, ISO 27001 certified, and HIPAA compliant with BAA available. OnePage is GDPR compliant with EU hosting, but has no third-party security certifications.
Do I need technical skills?
No developers needed. Everything is drag-and-drop with live preview and advanced logic built in. Unlike OnePage, where tracking beyond Meta and CRM integrations require GTM setup or Zapier, Heyflow connects natively with no code required.
Can I connect it to my CRM?
Yes. Heyflow integrates natively with HubSpot, Salesforce, Pipedrive, Zoho, HighLevel, and ActiveCampaign. OnePage only connects natively to HubSpot (with limited field mapping). Every other CRM requires Zapier.
What about Meta CAPI?
Both Heyflow and OnePage have native Meta CAPI. The difference is what comes next. Heyflow also ships native TikTok Events API, Bing CAPI, and code-free pixels for Google Ads, LinkedIn, Taboola, and Outbrain. OnePage stops at Meta.
