Forms and surveys decision
Orbit AI
A capable engineer can build a useful subset (forms + basic scheduling + LLM classification) in a few weeks using existing libraries, but reproducing the full polished product with 20+ integrations, AI agent nodes, analytics and support is heavy—so build a narrow replacement, keep paying for the full platform.

Open-source builds that already do this
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. All Orbit AI alternatives, with the arithmetic →
What a replacement has to do
- Collect submission via an embeddable form, enrich and classify the lead with an external LLM, persist contact and submission in a database, offer calendar booking that writes to Google/Outlook calendar, and trigger outbound or webhook automations.
What it still won’t have
- Polished multi-tenant UI and designer-grade drag-and-drop experience
- Built-in AI agent nodes and pre-baked Claude integrations
- All 20+ built integrations and single-vendor support/SLA
- Enterprise features (custom domains, advanced analytics dashboards, A/B testing)
- Priority support, dedicated onboarding, and bot protection out of the box
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal OrbitForms replacement: use React (Vite) frontend, Node.js (Express) API, and Postgres for storage; deploy backend on Heroku/Render and frontend on Vercel. Implement: embeddable form rendering, multi-page flows, conditional logic, file upload to S3, submissions/contact DB, Google Calendar OAuth booking (single-user sync), LLM-based lead classification via a hosted API (OpenAI/Anthropic), simple workflow runner supporting delays and webhooks, CSV export and basic analytics (counts, conversion rate). Out of scope: multi-tenant billing, A/B testing UI, SMS provider integration, deep admin/role-based enterprise features. Include input validation, OAuth error handling, retries for external API calls, unit tests for core APIs, and integration tests for booking and classification flows.

- 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.
