Our verdict on OpnForm
OpnForm is an open-source online form builder for individuals, teams, developers, and organizations. Its no-code tools support surveys, multi-page and single-page forms, conditional logic, validation, computed fields, file uploads, analytics, Stripe payment collection, and website or Notion embedding. The managed cloud service includes a permanent Free plan, while organizations can also deploy the software themselves. It is a strong fit for teams that want unlimited submissions and more control over deployment and data without starting with a paid subscription.
Pricing is straightforward across four monthly plans. Free includes unlimited forms and submissions, file uploads, form logic and validation, computed fields, API access, and basic integrations and webhooks. Pro costs $25 per month and adds branding removal, custom domains, custom SMTP, Discord, Slack, Telegram, an analytics dashboard, and AI form generation. Business costs $67 per month, adding multi-user roles and permissions, advanced branding, higher file upload limits, priority support, partial submissions, and versioning. Enterprise costs $220 per month and adds SAML and LDAP SSO, audit logs and compliance features, external storage support, a white-label hosting option, SLA, and onboarding support.
OpnForm’s main trade-off is breadth. It covers core form workflows well, with API access tokens, REST API support, webhooks, Zapier, Google Sheets, email, Slack, Discord, Telegram, Stripe, and self-hosted deployment. However, its listed integration set is smaller than what some broader form platforms offer, so teams with extensive prebuilt connector requirements should compare alternatives. Choose OpnForm when open-source access, unlimited submissions, calculations, uploads, payments, or deployment control matter most. Choose another product when a larger integration ecosystem is the primary requirement.
