What you give up either way
- No large integration catalogue (300+ native integrations)

- Enterprise-grade compliance features and attested HIPAA/PCI support
- Polished no-code UX, templates, and vendor support
- AI-powered document generation and eSignature bundled features
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Formstack Forms, and it does not prove anyone has run it for a month. How we decide.
