Heyflow alternative · ConvertSite
Heyflow is built for the funnel. ConvertSite is built for the quote.
In short_
Heyflow is a conversion funnel builder for marketing teams. Strong design control, mobile-first flows, and a well-earned reputation for making a form feel like a product.
ConvertSite is built for businesses where the price depends on the job. The flow does not just qualify the visitor, it prices them, and they see the number before they submit.
If your offer is the same for everyone and you need brand funnels at volume, Heyflow is a serious tool and you should try it. If your visitor’s real question is what will this cost me, that is what ConvertSite was built to answer.
In short_
Outgrow is a content marketing platform built for lead generation campaigns: quizzes, assessments, ROI calculators that attract and capture contacts.
ConvertSite is built for businesses that need to qualify buyers, show real-time pricing, and close sales without a sales call.
If you sell something with variable pricing or complex configuration, ConvertSite is purpose-built for that. If you're running content campaigns and need branded quiz funnels at scale, Outgrow has the depth.
The real purpose_
What each tool is actually built for
Heyflow started as a funnel builder.
ConvertSite is built around a different problem
When the offer depends on the customer, the page cannot answer the only question that matters. Heyflow gets you a better-qualified name. ConvertSite gets the visitor a price, a configuration or a booking, then sends you a lead who already saw it and kept going.
Logic here is a first-class object, not a step type. Zones, travel, tiered add-ons, minimums, surcharges. The pricing rules that currently live in your head can be in your site.

What's missing_
The feature Heyflow does not have
The Documents add-on ($50/month) generates a branded PDF proposal from a submission and emails it to the visitor the moment they finish.
A visitor completes your pricing flow, sees their quote on screen, and receives an itemised proposal they can forward to whoever signs off. No manual follow-up. No promise to send something within 24 hours.
For a service business that currently quotes by hand after every enquiry, that closes the loop.
What a customer actually experiences
A visitor completes your pricing calculator, sees their quote on screen, then immediately receives a branded PDF proposal in their inbox: itemised, on-brand, and ready to share with their team. No manual follow-up. No "we'll send a quote within 24 hours." The sale moves faster because the buyer has everything they need the moment they finish the tool.
The right tool for the job_
Who should use each tool
The key difference_
What the visitor leaves with
With Heyflow...
With ConvertSite...
The pricing happens on the page. The visitor selected their options, saw the number, and continued anyway. The enquiry that reaches you is price-aware. That is a different sales conversation, and often no conversation at all.
