Fillout vs HubSpot Forms: Which Is Better in 2026?

Fillout is the stronger form builder, with conditional logic, calculations and 50+ native integrations from its free tier, but it caps responses below $75/month. HubSpot Forms are free with unlimited submissions and write straight into HubSpot CRM, though capable forms need Marketing Hub Professional at $890/month.

These two products are barely competing for the same job. Fillout is a dedicated form platform that has spread sideways into scheduling, PDF generation, workflows and signatures, and it charges you by how many responses you collect. HubSpot Forms are a lead-capture front end for a CRM, given away because the CRM is what HubSpot sells, and priced by seats, marketing contacts and metered credits instead.

So the choice usually settles itself. If your company already runs on HubSpot and the form exists to create a contact record, the native path is hard to argue against. If the form has to calculate something, take a booking, generate a document or run an internal intake process, HubSpot's builder runs out of road quickly and Fillout does not. What both share is that growing costs more, in different currencies.

The Five Numbers That Decide It

Feature Comparison

Read this table with one thing in mind: Fillout is being rated as a form builder and HubSpot is being rated as a feature inside something larger. Fillout carries roughly 50 question types against HubSpot's 15 or so CRM-shaped fields, and the gap widens on everything downstream of the question itself.

Where Fillout Wins

The form itself is far more capable

Fillout gives away on its free tier what HubSpot charges $890/month to unlock. Conditional logic, branching, calculations, answer piping, pre-fill, multi-page forms, PDF generation, resume-in-progress and Stripe payments all sit on the $0 plan. HubSpot's builder has no formula field anywhere in its range, so a Fillout form can quote a price, score a quiz or size a project in the page, while the HubSpot equivalent has to hand that off to a Professional-tier workflow after the fact.

Unlimited seats on every plan

Fillout charges nothing per user at any tier, free included. HubSpot's free plan stops at two users, Starter is priced per seat at $20/month list, and Professional includes three Core Seats with each additional one from $45/month. For a six-person marketing team that difference alone is $135/month on Professional before anything else moves.

It does the jobs that usually need a second vendor

Scheduling, PDF document generation, e-signature fields and workflow automation are all inside Fillout rather than bought separately, which is a genuinely unusual spread for a product at this price. HubSpot has none of them on forms: there is no signature capability in the platform at all, so teams pair it with DocuSign or similar. A review by Hackceleration singled out this all-in-one breadth as Fillout's strongest argument, while noting that the advanced pieces take time to learn.

Where HubSpot Forms Wins

Submissions are uncapped, including on the free plan

HubSpot places no limit on form submissions at any tier. That is the exact axis Fillout meters, and on high-volume, low-complexity lead capture it makes HubSpot the cheaper answer by a wide margin. A landing page pulling 8,000 newsletter signups a month costs nothing on HubSpot and pushes Fillout onto the $75/month Business tier.

Nothing to integrate, because it is already the CRM

A HubSpot form submission creates or updates the contact record, adds it to lists, updates properties, triggers lead scoring and notifies the owner without any mapping. Fillout's native HubSpot connector is good, but it is still a connector: fields have to be matched, failures have to be monitored, and duplicate handling is a setting rather than a given. Progressive profiling is the sharpest example of the difference, since HubSpot can ask a returning visitor new questions because it already knows the old answers. Fillout has no equivalent.

The vendor is not going anywhere

HubSpot has been trading since 2006, is a public company with more than 10,000 staff, and publishes SOC 1, SOC 2 and SOC 3 reports alongside a full trust centre. Its 15,915 G2 reviews at 4.4 are more evidence than most software buyers ever get. Fillout, founded in 2022 and now operating as "Fillout (by Zite)" under Restly, Inc., has 30 G2 reviews and a Trustpilot score that has slipped from 4.7 to 3.5. If a procurement process is involved, this asymmetry matters more than any feature row.

Where Fillout Falls Short

• The response cap is the pricing model: 2,000 submissions on Starter and 5,000 on Pro, with the only uncapped tier an 87% jump to Business. Bulk submission packs exist but Fillout does not publish their price.
• Analytics sit behind the same door: conversion tracking, drop-off analytics and partial submissions all require Business at $75/month, so you cannot diagnose a leaking form until you are paying for volume you may not need.
• Lead-gen features are a $100/month add-on: abandonment recovery, lead enrichment, routing, autofill, email validation and ad conversion tracking are the Conversion Kit, not a plan feature. HubSpot bundles the equivalents into Marketing Hub.
• The product identity has split: help docs, security pages, the changelog and the AI credit pool have all moved to Zite, and the top tier is a $250/month bundle of both products.
• No HIPAA path at all: where HubSpot Enterprise will sign a BAA, Fillout will not.

Where HubSpot Forms Falls Short

• It is a thin form builder: around 15 CRM field types, no calculations, no scoring inside the form, no appointment booking, no signature field and no colour picker.
• Capable forms cost $890/month: smart fields, A/B testing, dependent fields and real workflows all land on Professional, with a mandatory $3,000 onboarding fee on top in year one.
• Every dimension of growth is billable: seats, marketing contact tiers and HubSpot Credits for AI and agent runs at $9 per extra 1,000 all move independently.
• Form analytics are shallow: no field-level reporting, no drop-off tracking and no partial submissions, a gap G2 reviewers raise repeatedly.
• Leaving means rebuilding: the forms are not usable outside HubSpot, so a CRM migration takes the forms with it.

HubSpot's form editor is widely documented inside its own academy; Fillout's is the one most buyers have not seen. This independent walkthrough covers the builder end to end.

Pricing Comparison

The two pricing models do not overlap enough to compare tier by tier, so compare the meters. Fillout meters responses and leaves seats alone. HubSpot leaves responses alone and meters seats, marketing contacts and AI credits. Work out which of those numbers grows fastest in your business and you have your answer.

A worked example: a six-person team collecting 6,000 submissions a month. On Fillout that is Business at $75/month billed annually, and $175/month once the Conversion Kit is added for lead routing and abandonment recovery. On HubSpot, staying on Starter at $20/seat is $120/month but leaves you without conditional logic; getting it means Professional at $890/month for three seats, $1,025 with the other three added, plus $3,000 of onboarding in the first year.

What Users Say

The review data is not comparable in the way the numbers suggest. HubSpot's 4.4 across 15,915 G2 reviews rates Marketing Hub as a whole, with forms rarely the subject; the recurring complaints are cost, contract inflexibility and a form builder users call basic. Fillout's 4.6 rests on 30 reviews, with only 4 on Capterra at 4.0, and its Trustpilot average of 3.5 across 48 reviews includes several accounts describing automated systems flagging and blocking them. Filip Konecny's independent review reaches a similar place, asking whether the paid tiers earn their price rather than whether the product works.

The Verdict

Pick HubSpot Forms if HubSpot is already your CRM, your forms are lead capture, and volume is the number that grows. You will get uncapped submissions for nothing and the tightest possible path from submit button to sales follow-up. Pick Fillout if the form has real work to do, if you need scheduling or documents or logic, and if your response volume is steady enough to sit inside a tier. Both answers are defensible, and each one is clearly wrong for the other team.

What neither answer gives you is a capable form builder with no meter attached. Fillout is capable and metered by responses. HubSpot is unmetered on responses and not capable. That is the tradeoff to resolve.

Consider Paperform Instead

Paperform Pro is $59/month, or $49 billed annually, with unlimited submissions and unlimited seats within fair use. Be clear about the cost: Fillout starts at $15/month and HubSpot Forms start at nothing, so on a small, simple, low-volume form both of them are cheaper and you should use them. For simple forms, use the simple tool. Paperform is priced for the team where the meter is the actual problem.

The structural argument is that charging more when your forms perform better is a tax on your own success, and Paperform declines to levy it in any of the three currencies these two use. No response cap, so a 6,000-submission month costs what a 600-submission month costs. No per-seat charge, so adding the sixth marketer changes nothing. No marketing contact ladder, because Paperform sends data to whichever CRM already holds it, HubSpot included, across 4000+ integrations.

The second argument is that the customer should not be the integration. One Paperform subscription covers three products on every plan: Paperform for forms, Papersign for eSignatures and Stepper for AI-native workflow automation, with one account and one bill. Against Fillout that replaces the $100/month Conversion Kit and the $250 Team bundle reasoning; against HubSpot it replaces a separate signature vendor entirely, since HubSpot has no eSignature product. Pro includes 25 signed documents a month and 20,000 automation credits; Business, at $149/month or $124 annually, includes 100 signed documents, 100,000 credits, 10 workspaces, SSO and the Business API. Support is in that price rather than sold as a $3,000 enablement line item at signing.

On capability, Paperform's Excel-style calculations go well past a total field: the same formulas control which questions and pages appear, what conditional emails say, what gets pushed to an integration and what the success page shows. Five payment processors are supported rather than one, with subscriptions, coupons, tax rules and refunds handled inside the form. The document-style editor builds the form as a page you can design, and the same form flips into Guided Mode one question at a time with no rebuild.

On vendor risk, Paperform has been shipping since 2016, bootstrapped and profitable, with no investors setting the roadmap. That is younger than HubSpot and considerably older than Fillout, and unlike Fillout there is no parent brand for the product to be folded into. The honest limits: Paperform is SOC 2 Type II, GDPR and CCPA compliant with SAML SSO and enforced 2FA on Business, but it is not HIPAA compliant and signs no BAAs, so regulated health data still points at HubSpot Enterprise. Paperform also has nothing like HubSpot's native CRM write-back, because it is not a CRM.
