Formidable vs SurveyJS

Formidable is a cloud form builder that generates forms from natural-language descriptions. Conditional logic can show, hide, or require fields based on answers and expressions. Computed fields evaluate in real time for weighted scores, boolean outcomes, and formatted outputs. Business rules can produce approve, reject, or escalation outcomes. Users can publish hosted forms, share links, embed forms in an iframe, and receive submissions through webhooks. A JSON REST API and the open-source Forma React library support custom interfaces. Account, form, and submission data are stored in the European Union. Generation prompts may be processed by Anthropic, while submission and respondent data are not sent to AI services. The Free plan costs nothing and includes one published form, 1,000 submissions per month, conditional logic, computed fields, webhooks, analytics, and a one-time AI-token allowance. Starter costs $15 a month; Pro costs $49 a month. Submissions beyond a plan limit are not accepted until the next billing cycle unless upgraded.

SurveyJS is a set of JavaScript components for building surveys, quizzes, polls, and web forms, then storing responses and displaying results. Its free, open-source Form Library renders JSON-based forms in React, Angular, Vue, and plain JavaScript applications. It supports more than 20 question types, conditional logic, validation, multilingual forms, and right-to-left languages. Survey Creator provides a drag-and-drop designer that generates JSON schemas. Dashboard displays results through interactive charts, tables, word clouds, and aggregated statistics; PDF Generator creates editable PDF forms and exports submissions. The libraries run in a customer’s application and can connect to any backend or database. SurveyJS says it does not access, process, or store survey data; customers choose and manage their own data storage and protections. React, Angular, and Vue have native support, while jQuery uses a wrapper over the Vanilla JavaScript version. The Form Library is free, but Survey Creator, Dashboard, and PDF Generator require commercial licenses for production use. Commercial developer licenses are required for each developer working with those product APIs or implementing integrations.
