|>Why we built this

We kept seeing the same pattern across client projects. A domain expert knows exactly what a form should do: which fields depend on which answers, what scores to compute, when to approve or reject. But translating that into working software takes weeks of back-and-forth with developers.

Formidable closes that gap. Domain experts describe requirements in plain language. AI generates a full form specification with validation, conditional logic, and business rules. Developers consume it via API or the open-source React SDK. Rule changes deploy instantly, no code changes needed.

|>What it does
01
Conditional logic
Fields that show, hide, and become required based on answers. Cascading dependencies across multi-page forms.
02
Computed fields
Real-time scores, ratios, and outcomes using FEEL expressions. Risk scores, BMI, debt-to-income, pass/fail.
03
Approval workflows
Business rules that approve, reject, or escalate. Multi-factor evaluation with computed risk tiers.
04
Headless by design
Open-source React SDK. Render forms in your own UI, validate via API. No iframes, no vendor CSS.
05
Describe, generate, deploy
Tell it what you need in plain language. AI generates the full spec. Publish with one click or consume via REST.
06
Open Forma spec
Declarative JSON with FEEL expressions. Export it, version it, render it yourself. No lock-in.
