TL;DR: Funnelforms in 30 seconds

  • 🧲 Interactive, multi-step request forms (funnel forms) that adapt dynamically to user input – for more & better leads.
  • 🔀 Conditional logic, drag & drop, appointment booking, file upload, price calculator; integrations with HubSpot, Pipedrive, ActiveCampaign, Mailchimp & more (+ Zapier).
  • 💸 Subscription from $22/month (Basic, annual) up to $317 (Enterprise); 14-day free trial (no credit card).
  • 🇩🇪 Originally from Germany, German-speaking support; usable as a WordPress plugin or a browser-based cloud app (v4).
  • ⚠️ Currently not recommended: critical vulnerability CVE-2026-39440 (Pro up to 3.8.1) without a publicly confirmed patch; the free plugin has been closed on WordPress.org since February 25, 2026 (as of October 12, 2026).

Many companies still rely on outdated, static forms that barely create a good customer experience. Yet it has never been easier to build a personalized, targeted funnel. With software like Funnelforms you can create an interactive request form in WordPress (or in the cloud) in minutes – one that reacts dynamically to your users’ input and generates significantly more high-quality leads with no extra effort.

In this article we show you how to turn your forms into a real funnel machine, what Funnelforms can do in 2026, what it costs, and why we currently do not recommend it despite its solid features.

Our rating: 3.9 / 5

Popular with existing users: an intuitive form-funnel builder with German-speaking support, 95% five-star reviews on Trustpilot (TrustScore currently 3.9 across 197 reviews, as of October 12, 2026). The heavy deduction: a critical vulnerability (CVE-2026-39440) for which no publicly confirmed vendor patch exists to date, plus removal from the WordPress.org directory. That is why we still do not recommend it (see the security notice below).

⚠️ Security notice (as of October 12, 2026): A critical vulnerability is documented for Funnelforms Pro up to and including version 3.8.1 (CVE-2026-39440, CVSS 9.9, remote code execution; reported January 25, 2026, published April 21, 2026). The public vulnerability databases still list no official patch: Patchstack states “No official patch available”, the NVD lists no fixed version. The only counter-statement comes from the vendor itself: the changelog in its members area lists a version 3.8.10 with “Patch for CVE-2026-39440”, undated, without a public announcement and without confirmation by any independent source. In addition, the free plugin “Funnelforms Free” has been closed on WordPress.org since February 25, 2026 (“Guideline Violation”); two further vulnerabilities in the free version (CVE-2025-68582, CVE-2025-62758) are also listed as unpatched by Patchstack.

What this means for you: According to Patchstack, a subscriber-level account is enough to exploit the flaw. If you keep running Funnelforms Pro: check in the plugin that at least version 3.8.10 is installed, get the patch confirmed in writing by support, disable open user registration in WordPress and review your user list. For new users we advise against it until an independently confirmed patch exists.

Our takeaway: As long as the patch is not publicly confirmed and the vendor does not comment, we do not recommend Funnelforms. We removed our affiliate links in August 2026.

What is Funnelforms?

Classic web forms are usually static: it doesn’t matter what a user clicked before – the next questions stay the same. Funnelforms is the opposite: an interactive, multi-step request form that branches dynamically based on each answer. If someone selects “no car”, the form won’t ask about car insurance later on.

On top of that you get choice blocks, free-text fields, sliders and more, so you ask exactly the relevant questions – without wasting your users’ time. Both sides benefit; Funnelforms itself cites significantly higher conversion rates. The tool was originally founded in Germany (2015, formerly known as “Anfrageformular”); today it is run internationally, with German-speaking support still available.

What is a sales funnel?

A funnel visualizes your customers’ decision process: from initial attention through interest and first contact to the close. After each step, some drop off – the funnel narrows. A good interactive form maps these steps and helps you guide more prospects all the way to an inquiry.

Funnelforms’ most important features

The goal is always to guide as many users as possible cleanly to an inquiry. To do that, Funnelforms offers, among other things:

  • Conditional logic (branching): follow-up questions adapt live to previous answers – the heart of any real funnel.
  • Drag-&-drop builder: assemble forms with no code, 100% responsive.
  • Single/multiple choice, free text, sliders, dropdowns: all common field types, including images/icons as answers.
  • Appointment booking & file upload: calendar sync, address input and uploads right inside the form.
  • Price calculator: instantly shows prospects an individual ballpark price.
  • Integrations: directly with HubSpot, Pipedrive, ActiveCampaign, KlickTipp, GetResponse, Mailchimp & more – plus thousands more via Zapier.
  • New (cloud/version 4): SMS/WhatsApp notifications and an “AI Leadcaller” (AI-assisted lead follow-up) – included depending on the plan.

Who is Funnelforms a no-brainer for?

This is YOUR tool if…

  • … you offer consultation-heavy products/services and want to pre-qualify prospects (e.g. agency, coaching, trades, B2B).
  • … you run on WordPress and want full data control – or prefer a cloud solution without your own site.
  • … static contact forms bring you too few and too poor leads.

Give it a miss if…

  • … a simple contact form is all you need – then Funnelforms is overkill.
  • … you’re on a very tight budget: it’s an ongoing subscription, not a one-time purchase.
  • … you do not want to keep an eye on the security situation yourself: without a publicly confirmed patch for CVE-2026-39440 you have to check the version status and backend hardening regularly (see the security notice).

How much does Funnelforms cost?

Funnelforms is a subscription (monthly or – about 20% cheaper – annual). The four tiers scale by websites, leads/month, integrations and extras like SMS/WhatsApp and A/B testing:

Plan Price / month* Key limits
Basic $22 1 website, 100 leads/mo, 5 forms, 3 integrations
Advanced $46 5 websites, 500 leads/mo, unlimited forms, 10 integrations, SMS/WhatsApp
Pro $117 10 websites, 1,000 leads/mo, A/B testing, 250 AI Leadcaller minutes
Enterprise $317 50 websites, unlimited leads & integrations, white-label

* Prices per month with annual billing; monthly billing is higher (approx. $27 / 57 / 147 / 397). The official pricing page is shown in US dollars. All plans come with a 14-day free trial (no credit card).

Pros and cons of Funnelforms

Pros

  • Clear dashboard with lead statistics
  • Fast to use thanks to drag & drop, no coding needed
  • Strong CRM/email integrations (HubSpot, Pipedrive, KlickTipp & co.) + Zapier
  • With the WordPress plugin, lead data stays on your own server according to the vendor; German-speaking support
  • Usable either as a WordPress plugin or a cloud app

Cons

  • Ongoing subscription instead of a one-time purchase; higher tiers get noticeably pricier
  • Overkill for simple contact forms
  • Possible feature overlap with an existing CRM
  • Unresolved security situation: critical vulnerability CVE-2026-39440 without a publicly confirmed patch, free plugin removed from the WordPress.org directory

What are the alternatives?

The closest comparisons are Heyflow and Perspective (both work without WordPress too, but can be pricier depending on limits) as well as classic funnel-form plugins. For purely static contact forms, tools like Contact Form 7 or WPForms are often enough – but they don’t offer real, branching funnel logic.

Conclusion – a good tool, but currently not recommended

Functionally, Funnelforms remains a good tool: interactive, branching forms extract measurably more and better leads from the same traffic than static contact forms, and the builder with its CRM integrations convinced us in testing.

Nevertheless, we still do not recommend it. The reason is not the functionality but the security situation: a critical vulnerability is documented for Funnelforms Pro up to version 3.8.1 (CVE-2026-39440, CVSS 9.9). As of October 12, 2026, Patchstack and the NVD list no official patch. The vendor only mentions a version 3.8.10 with a patch in its non-public changelog, undated and without a statement. The free plugin has been removed from the WordPress.org directory since February 2026. Until an independent source confirms the patch, we advise against new installations. Existing users should update to at least version 3.8.10, disable open registration and harden the WordPress backend. As soon as the patch is publicly confirmed and a clear statement is available, we will update this review.

Frequently Asked Questions (FAQ)

How much does Funnelforms cost?
Funnelforms is a subscription (monthly or – about 20% cheaper – annual). Tiers start at roughly $22/month (Basic, annual; $27 monthly) and go up via Advanced ($46) and Pro ($117, incl. A/B testing) to Enterprise ($317). The official pricing page is shown in US dollars. There is no standard one-time license anymore.
Do I strictly need WordPress for Funnelforms?
No longer. Classically, Funnelforms is a WordPress plugin – but there is now also a cloud app (version 4) that runs entirely in the browser and does not require WordPress. If you do use WordPress, your lead data can stay on your own site.
Is there a free version?
There is a 14-day free trial on all plans (no credit card). The old free “Funnelforms Free” version that used to be on WordPress.org was removed there in early 2026 and is no longer available for download – so use the trial to test it.
Is Funnelforms GDPR-compliant?
The vendor advertises GDPR compliance. What can be verified: with the WordPress plugin, lead data stays solely on your own website according to the vendor, and the licensing and update system runs on AWS servers in Germany according to the terms of service. The provider is now Funnelforms LLC, based in Wyoming (USA). For the cloud app (version 4) the website names no server location, and the app privacy policy mentions Google Firebase with possible transfers to the USA. We could not find a data processing agreement (DPA) for download, so ask support for it before using the cloud app.
Is Funnelforms secure?
Not without reservations at the moment. The critical vulnerability CVE-2026-39440 (CVSS 9.9) is documented for Funnelforms Pro up to version 3.8.1. As of October 12, 2026, Patchstack and the NVD list no official patch; the vendor only names a version 3.8.10 with a patch in its members area, undated and without public confirmation. The free plugin has been removed from the WordPress.org directory since February 2026, and two of its vulnerabilities are also listed as unpatched. If you use Funnelforms Pro: update to at least 3.8.10, get the patch confirmed in writing by support, disable open registration and harden the backend.
