Formsite vs Formstack: Same Parent Company, Two Products in 2026

This comparison comes with a significant caveat: Formstack acquired Formsite in December 2023. They are now the same company. Formsite, founded in 1998, is one of the oldest form builders on the internet — 28 years of continuous operation. Formstack, founded in 2006, grew into a broader workplace productivity platform covering forms, documents, and e-signatures. In late 2023, Formstack brought Formsite under its umbrella, creating the unusual situation of one company owning two competing form builders.

The question is no longer simply "which is better?" but rather "which one will Formstack continue to invest in?" The answer, based on team size, development velocity, and product breadth, clearly favours Formstack's own platform. This page compares the two products as they exist today — but users should understand they are evaluating two products from the same company with very different trajectories.

Feature Comparison

Two products from the same company — but the feature gap is wide.

Where Formsite Wins

Lower Entry Price

Formsite's Personal plan starts at $21/month versus Formstack's Starter at $50/month. For basic form building — contact forms, simple surveys, feedback collection — Formsite is genuinely cheaper. The free plan is extremely limited (5 forms, 10 results per form), but paid plans offer reasonable value for straightforward use cases. If you need forms and nothing else, Formsite costs less.

Per-Form Result Limits

Formsite counts submissions per form rather than pooling them monthly. The Business plan allows 2,500 results per form across 25 forms — theoretically 62,500 total results. For accounts with many moderate-volume forms, this model can be more generous than Formstack's pooled monthly limits. It is an unusual pricing model, but it advantages certain use patterns.

28 Years of Operational History

Formsite has processed billions of forms since 1998. That track record demonstrates reliability and data handling competence over a timeframe no other form builder can match. Whether that history translates into future reliability under new ownership is the open question.

Where Formstack Wins

Broader Product Suite

Formstack is not just a form builder — it includes Formstack Documents (document generation and automation), Formstack Sign (e-signatures), and workflow automation. Formsite builds forms. Formstack builds forms, generates documents, collects signatures, and automates workflows. For organisations that need more than just data collection, Formstack eliminates the need for separate document and signing tools.

Active Development and Larger Team

Formstack has 201-500 employees and raised $425M in funding. Formsite lists 2-10 employees. The development velocity gap is enormous. Formstack regularly ships new features, integrations, and platform improvements. Formsite's update cadence has slowed since the acquisition, and with a tiny team, major feature additions are unlikely. If you are choosing a platform for the next 3-5 years, Formstack's investment trajectory is clearly stronger.

Enterprise Features

Formstack offers HIPAA compliance, SSO, data encryption, audit trails, role-based access, and SOC 2 compliance across its platform. Formsite offers HIPAA only on the $209/month Enterprise tier. For regulated industries and enterprise deployments, Formstack provides a more comprehensive security and compliance package.

Salesforce Integration

Formstack has deep, native Salesforce integration — forms that map directly to Salesforce objects, prefill from Salesforce data, and push submissions back without middleware. Formsite offers Salesforce integration only on the Enterprise plan. For Salesforce-centric organisations, Formstack's integration is significantly more capable and available on lower-tier plans.

Where Formsite Falls Short

• Acquired with uncertain future: Now owned by a company that already has a competing form builder. No public roadmap for Formsite's continued development.
• Tiny team: 2-10 employees limits development velocity, support capacity, and security response times.
• Dated interface: The editor and form output feel like products from the mid-2000s. Design quality lags every modern competitor.
• Restrictive free plan: 5 forms, 10 results per form, no payments, no integrations — barely functional as a trial.
• No e-signatures: Formstack includes Formstack Sign; Formsite has no native signing capability.
• No document generation: Formstack includes Formstack Documents; Formsite offers basic PDF export but no document automation.
• No AI capabilities: No AI form generation or intelligent features of any kind.

Where Formstack Falls Short

• Expensive entry point: $50/month Starter is 2.4x Formsite's $21/month Personal plan. For basic form building, Formstack is hard to justify on price.
• Venture-funded with acquisition history: Formstack raised $425M and has made multiple acquisitions. The growth-at-all-costs model means pricing may continue rising.
• Form design quality: While more modern than Formsite, Formstack's forms still look like standard web forms rather than designed pages.
• Complex pricing: Formstack's pricing varies by product combination (Forms, Documents, Sign) and can be confusing to navigate.
• No free plan: Formstack offers no free tier — only a 14-day trial. Formsite at least has a (very limited) free plan.

Pricing Comparison

Formsite is cheaper for basic forms. Formstack is more expensive but includes a broader product suite.

What Users Say

Formstack averages 4.1-4.4/5 across G2 and Capterra with thousands of reviews. Users praise the Salesforce integration and document automation but frequently cite pricing as steep and the interface as utilitarian. Formsite averages 4.3-4.5/5 across fewer reviews (~180), with praise for reliability and complaints about the dated interface. Post-acquisition, some Formsite users express uncertainty about the platform's future direction.

Consider Paperform

If the Formsite-Formstack ownership situation gives you pause, Paperform offers a refreshing alternative. Founded in 2016, bootstrapped and profitable, Paperform has no corporate parent and no acquisition risk. Its document-style editor produces forms that look like designed landing pages — a generation ahead of both Formsite and Formstack visually. Every plan includes five payment gateways (Stripe, PayPal, Square, Braintree, Google Pay), an Excel-style calculation engine for dynamic pricing and scoring, built-in e-signatures via Papersign, and 30,000+ templates. For businesses that want modern design, powerful functionality, and platform independence, Paperform is worth evaluating. See the full form builders ranking for details.
