Endatix vs Formidable

Endatix is a self-hosted, open-source platform for managing forms and surveys, with deployment options for teams that need control over their data. Its SurveyJS-based drag-and-drop builder supports more than 20 question types, conditional logic, validation, themes, custom question types and multiple languages. Forms can collect anonymous or authenticated responses, accept partial submissions that respondents resume later, and be versioned without breaking existing submissions. Pre-filled forms can draw on historical submissions or third-party integrations. Webhooks can trigger notifications, follow-up actions and data transfers to CRM or chat apps. Submissions and codebooks export to CSV, XLSX, XML and PDF. Storage options include Azure Blob Storage, Amazon S3, RustFS and other S3-compatible providers. Endatix runs natively or in Docker on Linux, Windows Server and macOS, and can be deployed on cloud or on-premises infrastructure. The self-hosted Headless API is free under an MIT license; hosted Endatix Cloud starts at $360 per month. Hub license pricing depends on the number and type of environments.

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.
