OpnForm is an open-source online form builder centered on “unlimited forms and unlimited submissions.” It can be used to collect leads, registrations, feedback, files, and data for internal workflows. It offers both a hosted cloud version and a self-hosted version. Compared with traditional form tools that charge based on response volume, its cost model is better suited to teams with unpredictable or rapidly growing submission volumes.
In terms of functionality, the free plan already covers the key basics of form building: file uploads, conditional logic and validation, calculated fields, prefill, URL parameters, API access, Webhooks, and basic integrations. Pro adds more professional presentation features, including brand removal, custom domains, custom SMTP, password protection, form expiration, Captcha, analytics dashboards, and AI form generation. Business is aimed at teams and agencies, adding role-based permissions, advanced branding, higher file upload limits, partial submissions, version control, and advanced integrations. Enterprise focuses on SSO, audit logs, compliance, external storage, white-label hosting, SLA, and onboarding support.
The hosted version uses a freemium subscription model. Free is $0; Pro, Business, and Enterprise show two different sets of monthly prices in different parts of the page: $25/$67/$220, and $29/$79/$250 in the feature comparison table. It is recommended to confirm the final billing amount before purchasing. Annual billing saves 15%, and users can upgrade, downgrade, or cancel at any time. The self-hosted Community Edition is free OSS, while the enterprise self-hosted license costs $1,999/year/instance. There is currently no automated paid trial, but you can contact the team for evaluation.
Its main strengths are that the free plan is very generous, does not limit submissions, and includes API and Webhook access. Meanwhile, being open source and self-hostable reduces the risk of vendor lock-in. The enterprise roadmap is also fairly clear, covering permissions, SSO, audit logs, and external storage. The drawbacks are that multi-user collaboration on Free and Pro gives all users full admin rights, so permission governance requires Business or above; advanced security and compliance features are mainly concentrated in Enterprise; pricing is inconsistent across the page; and specific compliance certifications are not disclosed.
It is suitable for SaaS teams, marketing operations, education/nonprofits, agencies, and technical teams that want self-hosting. If you only need simple questionnaires, Google Forms, 问卷星, or 金数据 may be more localized options; if interactive experience matters more, you can compare it with Typeform, Jotform, and Tally. The text does not specify access conditions from China. Stripe card payments may pose a barrier for some domestic teams, so it is advisable to test network connectivity, payment, and email delivery before deployment.
