FormAssembly vs Gravity Forms: Salesforce SaaS or WordPress Plugin? (2026)

FormAssembly and Gravity Forms represent two entirely different architectures. FormAssembly is a standalone SaaS platform built around Salesforce integration and enterprise compliance — starting at $59/month. Gravity Forms is a WordPress plugin that extends WordPress with powerful form capabilities — starting at $59/year. They share almost no target audience.

The primary decision factor is your tech stack. If you run WordPress, Gravity Forms is the native choice. If you need Salesforce integration with enterprise compliance, FormAssembly is purpose-built for that. The two rarely compete directly.

Feature Comparison

Side-by-side across feature categories — SaaS enterprise vs WordPress plugin.

Where FormAssembly Wins

Salesforce Integration Depth

FormAssembly's native Salesforce connector supports multi-object mapping, prefilling from Salesforce records, and Agentforce support — the deepest Salesforce integration available in any form builder. Gravity Forms can connect to Salesforce via third-party add-ons and Zapier, but these provide only basic single-object field mapping. For organisations where form-to-Salesforce data precision is critical, FormAssembly is the only serious option.

Platform-Level Compliance

FormAssembly holds HIPAA with BAA, PCI DSS Level 1, SOC 2, GDPR, FERPA, and FedRAMP High. As a SaaS platform, these certifications cover the entire stack. Gravity Forms is self-hosted, so compliance depends on your WordPress hosting, server configuration, and security practices. For regulated industries where vendor-managed compliance simplifies procurement, FormAssembly's certifications are a decisive advantage.

CMS Independence

FormAssembly works independently of any CMS. You can embed forms on any website, share via links, or use them in standalone workflows. Gravity Forms requires WordPress — if you migrate away from WordPress, your forms don't come with you. For organisations that might change their CMS or need forms across multiple platforms, FormAssembly's independence is valuable.

Where Gravity Forms Wins

Price: $59/Year vs $59/Month

Gravity Forms' Basic license costs $59/year — the same as one month of FormAssembly. The Elite license at $259/year still costs less than five months of FormAssembly's entry plan. For WordPress-based businesses, Gravity Forms delivers powerful form capabilities at a fraction of FormAssembly's cost. The annual pricing model also means no monthly recurring charges beyond WordPress hosting.

WordPress Ecosystem

Gravity Forms has the deepest WordPress integration of any form plugin. Native compatibility with popular themes, page builders (Elementor, Divi, Beaver Builder), and a massive add-on ecosystem for payments, CRM connections, email marketing, and advanced features. FormAssembly can be embedded in WordPress via iframe, but the integration is surface-level compared to Gravity Forms' native WordPress hooks and filters.

Self-Hosted Data Control

Form submissions are stored on your WordPress server — you control the data, the backups, and the infrastructure. FormAssembly stores data on their servers. For organisations with data sovereignty requirements or those who prefer self-hosted solutions, Gravity Forms' architecture puts data control entirely in your hands.

Developer Extensibility

Gravity Forms' hooks, filters, and REST API make it extremely extensible for WordPress developers. Custom field types, conditional logic extensions, and workflow automation can be built with PHP. FormAssembly is a closed SaaS platform with less developer extensibility. For WordPress development teams, Gravity Forms is a more flexible foundation.

Where FormAssembly Falls Short

• Expensive: $59/month vs $59/year. The 12x price difference is hard to justify without Salesforce or compliance needs.
• Steep learning curve: G2 ease of use rated 4.1/5. Non-Salesforce users find the interface unintuitive.
• Limited integrations: Roughly 20 native connectors, no Zapier or Make. Outside Salesforce, connectivity is poor.
• No free plan: Only a 14-day trial. Gravity Forms at least offers a 30-day refund guarantee.

Where Gravity Forms Falls Short

• WordPress dependency: Cannot function without WordPress. If you leave WordPress, you lose your forms.
• No native Salesforce depth: Third-party add-ons provide basic mapping only. Complex multi-object sync isn't possible.
• Self-managed compliance: No platform-level HIPAA, FedRAMP, or PCI DSS. You're responsible for the entire stack.
• Hosting overhead: You need WordPress hosting, maintenance, updates, and security. FormAssembly is fully managed.
• No standalone forms: Forms live inside WordPress. Sharing via direct link requires extra configuration.

What Users Say

Gravity Forms earns consistent praise from WordPress developers for its extensibility, reliability, and deep ecosystem. FormAssembly reviews focus on Salesforce integration quality. The audiences rarely overlap — WordPress developers choose Gravity Forms; Salesforce admins choose FormAssembly. Complaints about FormAssembly centre on price and learning curve; complaints about Gravity Forms centre on WordPress dependency and occasional plugin conflicts.

Consider Paperform

If FormAssembly's Salesforce focus is overkill and Gravity Forms' WordPress requirement is a limitation, Paperform offers a standalone SaaS alternative. Paperform's document-style editor creates forms that look like designed landing pages, with an Excel-style calculation engine for dynamic pricing, scoring, and conditional logic.

At $24/month (annual), Paperform costs less than FormAssembly ($59/mo) and works without WordPress. It includes five payment gateways, 2,000+ integrations, 30,000+ templates, and a free plan. For businesses that need more than a WordPress plugin but less than a Salesforce specialist, Paperform is worth evaluating. See our full ranking for details.

The Verdict

Choose FormAssembly for Salesforce-centric enterprises. Its native multi-object Salesforce connector and FedRAMP + HIPAA + PCI DSS compliance serve regulated industries where form-to-CRM data precision matters. Founded in 2006, FormAssembly's 20-year track record provides enterprise procurement confidence.

Choose Gravity Forms for WordPress-based businesses. At $59/year, it delivers powerful form capabilities within WordPress at a fraction of FormAssembly's cost. The deep plugin ecosystem, self-hosted data control, and developer extensibility make it the best form solution for WordPress. Gravity Forms (Rocketgenius) has been in the market since 2009 — a stable, mature platform.

Frequently Asked Questions

Can Gravity Forms integrate with Salesforce?

Yes, through third-party add-ons and Zapier, but the integration is surface-level — basic field mapping to single Salesforce objects. FormAssembly's native Salesforce connector supports multi-object sync, prefilling from Salesforce records, and Agentforce support. If your WordPress site needs to feed data into complex Salesforce data models, FormAssembly is significantly more capable. For basic lead capture to Salesforce, Gravity Forms with Zapier may suffice.

Do I need WordPress to use either platform?

Gravity Forms requires WordPress — it's a WordPress plugin and cannot function without a WordPress installation. FormAssembly is a standalone SaaS platform that works independently of any CMS. If you don't have WordPress, Gravity Forms isn't an option. If you're moving away from WordPress, FormAssembly (or another SaaS form builder) gives you CMS independence.

Which is more affordable for small businesses?

Gravity Forms starts at $59/year (Basic license) — significantly cheaper than FormAssembly's $59/month. Even Gravity Forms' Elite license at $259/year costs less than four months of FormAssembly's Explorer plan. However, Gravity Forms requires WordPress hosting costs on top. Neither platform offers a free plan. For WordPress-based small businesses, Gravity Forms is dramatically more affordable. For businesses without WordPress, FormAssembly's SaaS model avoids hosting overhead.

Which has better compliance certifications?

FormAssembly holds HIPAA with BAA, PCI DSS Level 1, SOC 2, GDPR, FERPA, and FedRAMP High — the broadest compliance portfolio among form builders. Gravity Forms is a self-hosted WordPress plugin, so compliance depends entirely on your hosting environment and configuration. You can achieve HIPAA or PCI compliance with Gravity Forms, but you're responsible for the entire stack. FormAssembly handles compliance at the platform level, which is simpler for regulated organisations.
