Two popular form builders compared on the same 25-row feature matrix and pricing, with FormBuilder shown as a third column so you can see another option to consider.
Overview
Formstack started as an online form builder in 2006 and has grown into a workflow suite: Formstack Forms (the builder), Formstack Documents (merge submissions into PDFs, Word files and contracts), and Formstack Sign (e-signature). The pitch is that one platform can take a request from intake form to generated document to signed agreement without code, which is why it sells mainly to operations, HR, healthcare and higher-ed teams.
The form builder itself is capable rather than flashy: drag-and-drop fields, conditional logic, multi-page forms, calculations, save-and-resume, payments (Stripe, PayPal, Authorize.net and others), workflows with approvals, and 300+ integrations. Its Salesforce apps are a genuine differentiator — forms that read and write Salesforce records natively and can live inside Experience Cloud — and it offers HIPAA compliance, PCI and SOC 2 for regulated buyers.
OrbitForms is less a form builder than a lead-capture stack with a form on the front. The core is a drag-and-drop form and conversational "Flow" builder with conditional logic, multi-page forms and file uploads, but the reason it exists is what happens after submit: a calendar-synced scheduler (Google Calendar / Outlook, Zoom / Meet links, round-robin and group booking), an "AI SDR" that scores and routes leads against your ideal-customer rules, a visual workflow builder, multi-channel email and SMS sequences, and a contact database with tagging and ownership.
Pricing is aimed at sales and marketing teams rather than individuals. There is a 7-day free trial but no free tier. Pro is $29 a month ($23.20 annual) for up to 10 forms and 1,000 responses a month with branding removed, custom CSS, Slack and webhooks, and 3 workflows. Business is $149 a month ($119.20 annual) for unlimited forms, 10,000 responses, scheduling, AI-agent workflows, lead classification, A/B testing and partial submissions. Advanced is $249 a month ($199.20 annual) for 100,000 responses, sequences, SMS and custom domains. Integrations include Clay, HubSpot, Slack, Zapier, Google Sheets, Notion and Salesmsg.
