OpnForm is an open-source online form builder whose core positioning is to let users create forms, surveys, and workflows for free while maintaining complete control over their data. According to official information, it sets no limit on the number of responses; even the free plan can collect unlimited responses, with no per-response charges, hidden quotas, or unexpected overage fees.
In terms of main capabilities, OpnForm provides an AI form builder to help users quickly create forms. For form design, users can drag and drop fields, apply themes, use multi-page layouts, and choose between conversational or classic form styles, thereby creating professional-looking forms without needing a designer. Responses collected by forms can seamlessly connect to the tools users already have: it supports both native integrations and connecting to any system via Webhooks and a public API. Users can also choose a suitable distribution method to share forms.
In terms of usage, OpnForm offers multiple deployment options: users can use its cloud service, EU-hosted service, or self-host it when full ownership is required. It is designed for privacy-focused organizations and is fully open source. It offers flexibility for individual users, while for teams it provides scalable management features, including shared workspaces, clear role division, and full audit visibility; it meets internal compliance requirements through SSO access, domain control, and more advanced support. Users can also fully brand forms or offer white-label solutions to clients.
Applicable scenarios include: enterprises or teams collecting secure, high-quality data; organizations that need to manage forms at scale and coordinate cross-team work; privacy-first institutions with data sovereignty requirements that want self-hosting or EU hosting; and individuals and creators who want to create forms and surveys for free with no response limits.
In terms of limitations, the materials do not provide specific pricing plan details, the specific functional boundaries of the AI form builder, a complete list of various integrations, the technical requirements for self-hosting, or platform limitations.
