Forms and surveys decision
Formstack Forms
A competent developer can build a basic hosted forms product (form builder, storage, webhooks, embeds) in about a week, but reproducing Formstack’s large integration catalog, enterprise compliance attestations, Salesforce-native products, AI document generation, and polished no-code UX would be costly and time-consuming—so building a narrow replacement is realistic, replacing the full paid product is not.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Collect form submissions, store them, and forward or display results (email/webhook/CSV) with a small web UI for creating basic forms.
What it still won’t have
- No large integration catalogue (300+ native integrations)
- Salesforce-native, in-org forms and one-click document generation
- 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
What remains hard
- Integration maintenance
300+ Integrations
- Compliance and regulation
Formstack offers enterprise-level solutions that support HIPAA compliance obligations.
- Brand trust
Formstack’s workplace productivity suite helps over 32,000+ organizations digitize what matters, automate workflows, and fix processes—all without code.

Runnable build prompt
Build a minimal hosted form-builder and submission service using React for the frontend, Node.js + Express for the API, and Postgres for storage. Core features in scope: WYSIWYG form editor (create fields, validation, conditional logic), public form rendering and submission endpoint, store responses in Postgres, email notifications via SendGrid, webhook forwarding with retry/backoff, embed script for third-party sites, and a basic admin dashboard to view/download submissions. Out of scope: Salesforce-native in-org app, AI document generation, eSignatures, and a 300+ integrations marketplace. Include input validation, authentication for the admin UI, error handling, and unit/integration tests for API endpoints.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
