OpnForm
Open-source form builder with analytics and spam protection

OpnForm is an open-source web application for building and sharing online forms, collecting submissions, and managing responses. It aims to provide a modern alternative to hosted form tools with a clean builder, theming, and integrations.
Key Features
- Form builder with multiple field types and configurable form settings
- Shareable form pages and embeddable forms for websites
- Custom domains and branding options for published forms
- Spam protection features (e.g., CAPTCHA/anti-bot options depending on setup)
- File uploads on form submissions (storage depends on deployment configuration)
- Submission management with export options (e.g., CSV) and basic analytics
- Email notifications and webhook-based integrations for automations
- Team/workspace features and access control (plan/edition dependent)
Use Cases
- Collect leads and contact requests on a marketing or company website
- Run surveys, registrations, and internal data collection workflows
- Replace hosted form products while keeping data under your control
Limitations and Considerations
- Some features and collaboration capabilities may differ by edition/plan and deployment configuration.
- Advanced reporting and deep workflow automation may require external tools via webhooks/integrations.
OpnForm is a strong fit for individuals and teams that need a polished, customizable forms product with common integrations and ownership of form data. It provides core form-building and response-handling features while remaining extensible through webhooks and configuration.
