What each Formstack plan includes
Formstack has no free plan. Forms is $83/mo paid annually ($99 monthly) for one builder user, 25 forms and 1,000 submissions per form. Suite is $250/mo paid annually ($299 monthly) for three builder users, 100 forms and 5,000 submissions per form, plus document generation and e-signatures.
The submission allowance is counted per form, not across the account. Add up the forms you run and the volume each one receives before comparing the headline price.

Per-form submission limits change the maths
A plan that includes 1,000 submissions per form is not the same as 1,000 submissions across the account. If you run several busy forms, the effective allowance is larger; if one form takes most of the traffic, the per-form cap is the number that matters.
Check the builder-user and form counts too. Forms includes one builder user and 25 forms; Suite includes three builder users and 100 forms.
Where Formstack is genuinely strong
Formstack's differentiators are document generation, e-signatures, workflow automation, HIPAA add-ons and Salesforce-native forms. Those are real product strengths that a simple form backend does not replace.
Its integration catalogue covers 250+ services, including Salesforce, Google Sheets, HubSpot, Airtable, Stripe, PayPal and Zapier. The REST API and webhook endpoints support real-time submission delivery.
Where splitforms fits
splitforms is an HTML form backend that works on any host. Free includes 500 submissions total with no card, and Pro is $5 per month for 5,000 submissions a month with signed webhooks.
Keep Formstack when its builder, documents, signatures or compliance features are the reason you are paying. Choose splitforms when the form already lives on your site and you need storage, email, spam filtering and webhooks at a lower price.
