Top 5 form builders that integrate with Hubspot: syncing leads with your CRM

If you clicked on this article, you probably agree with us that HubSpot forms are highly limited. So now you're looking for a comprehensive third-party form solution that also allows you to send data into your CRM. We totally get you, as data collection is only the starting point of lead generation or feedback processing. Whether you're collecting signups, demo requests, or asking for feedback, your form tool must do more than just gather data. It should deliver it straight to your CRM.  And since for many marketing, sales , project management and customer relations professionals this CRM tool is often HubSpot, we complied a list of five form builders that not only integrate well with HubSpot, but also offer a smoother, smarter way to collect leads.

Why use a third-party form builder instead of HubSpot native forms?

HubSpot forms make sense if you're already paying for the right tier and need a quick internal option. But they fall short on design flexibility, conditional logic, and overall UX control. You also can’t fully customise styling or embed them as freely as you might want. If branding, integrations, or user experience are a priority, third-party tools often do a better job—and in many cases, they’re free or cheaper than upgrading your HubSpot plan just to unlock better forms.

What to look for in a form builder for HubSpot CRM?

Native integration

First of all, a form builder that you'll use for sending data to HubSpot should have a native user-friendly integration with the CRM platform. The smoother the connection, the faster your leads reach your CRM.
If the tool also offers third-party automation tools like Make or Zapier, it's a good bonus. For example, you can connect form data with HubSpot via Make which allows for more complex set-ups like adding filters or conditions to triggers, and more.

Conditional logic & personalisation
A form builder for HubSpot should support robust conditional logic to improve the data quality you're sending into your CRM. Using logic allows you to ask relevant follow-up questions and hide irrelevant steps based on user input, which is a must for lead gen forms or feedback surveys.

If you're collecting leads, adding a personal touch to the form can break the ice between you and the prospect. Answer piping adds this personal layer, by letting you reference a respondent’s name or input in later questions.  This small detail can make the form feel more conversational and boost engagement.

Branding and design flexibility
One of the reasons to use a third-party form builder for HubSpot is design customisation. Choose a form builder that lets you match forms with your brand, add brand elements like logos and fonts, customise layouts and upload images.

Multi-page forms

HubSpot's native form builder does not natively support multi-step forms. Therefore, if you don't want to limit your lead gen form to just one question, you need an external form tool that provides a smooth multi-step flow. And if you’re using AI form generator (like in Weavely), it can automatically split questions into logical pages with an optimised number of questions, improving completion rates.

Email notifications and autoresponders
Instant alerts for your team and confirmation emails for the user help keep everyone in the loop and start engagement early. Email notifications ensure your team gets alerted as soon as someone submits a form, so that no lead or request goes unnoticed. Meanwhile, autoresponders can send a confirmation email to the user, thanking them or sharing next steps. These features are especially important in lead generation or customer feedback scenarios, so look for tools that offer them out of the box.

CRM-focused extras
Depending on your use case and goals, you might need some extra features when sending data to HubSpot. This could be updating existing contacts or adding UTM tracking.

Frequently asked questions

Do I need a HubSpot subscription to use these integrations?

Yes, you’ll need at least a free HubSpot account to connect any form builder. Some features, like custom field mapping or automation may require a paid HubSpot plan depending on the tool.

Is it better to use a native HubSpot form?

Not always. Native HubSpot forms are convenient but limited in design flexibility and advanced features like conditional logic. Third-party tools often offer a better user experience and more control over how data is collected and displayed.

Can I send leads to multiple HubSpot properties?

Most form builders with direct HubSpot integration allow field mapping to multiple properties (like name, email, company, etc.). The extent of customisation depends on the form tool and your HubSpot plan.

What’s the difference between native HubSpot integration and Make/Zapier?

Native integration is typically faster and more direct. Make and Zapier give you more flexibility, like connecting to multiple tools, filtering responses, or triggering additional automations. But they may require more setup.

Do these form tools store responses outside of HubSpot too?

Yes, typically your form responses are saved both in the form builder’s dashboard and in HubSpot. This gives you a backup and lets you review submissions even if your CRM setup changes.
