Forms and surveys decision
Formflow
A competent engineer can recreate a useful subset (conditional embeddable funnels, validation, OTP, webhooks, basic analytics) in ~1 week and run it cheaply, but full parity (AI Copilot, wallet/credits, polished visual editor, A/B testing, and platform polish/support) is larger and better justified by the hosted product.

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 multi-step submissions, evaluate/route leads with conditional logic, validate contact data in real time, deliver notifications (email/SMS), and store/export responses.
What it still won’t have
- AI Copilot that generates full funnel flows automatically
- Built-in Wallet credit system and bundled premium action credits
- FlowSplit A/B testing UI and advanced analytics polish
- Hosted templates, 24/7 in-app support, and white-glove onboarding
- Deep product polish (editor UX, style editor, pre-built themes) and nontrivial features like Calculation Engine/Quiz mode polishing
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted lead-funnel service using React for the editor/embed UI, Node.js/Express for the API, and PostgreSQL for storage; deploy frontend on Vercel and backend on Render (or a single VPS). In scope: multi-step forms with drag-configurable conditional branching (save JSON-defined flows), embeddable form script, partial-save/session resume, real-time email validation via a mailbox-validation API, OTP phone verification and SMS send via Twilio, webhooks and CSV export, and a simple responses dashboard with basic in-flow analytics (timestamps, drop-off rates). Out of scope: an AI Copilot that generates flows, advanced visual theme editor, FlowSplit UI for A/B testing, and a credit/wallet system. Include input validation, rate limiting, logs, error handling, and automated tests for API endpoints and critical client flows.
How we checked
How the score was reached

- 5 cited sources+3
- Price verified on pricing page+3
- 3/3 assessment runs agreed+4
- Evidence score67
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.
