OpnForm

OpnForm is a form and survey builder that emphasizes unlimited responses. Users drag and drop fields to build single-page or multi-step forms in a classic or conversational style, add conditional logic, validation and computed fields, apply custom themes, and collect file uploads and Stripe payments. Integrations include Slack, Discord, Telegram, Google Sheets and Zapier, along with webhooks and a public REST API. Paid plans add AI form generation, custom domains, password-protected forms, captchas, analytics and team features.

The tool suits individuals, startups, agencies and enterprises that want to avoid per-response limits or platform lock-in. It can be used on OpnForm's cloud, with EU hosting, or self-hosted from its open-source code. Features were not tested for this listing.

The free plan costs $0 and includes unlimited forms and submissions, basic file uploads, logic, the API and basic integrations, with OpnForm branding. The pricing page shows two sets of figures for paid plans: plan cards list Pro at $25, Business at $67 and Enterprise at $220 per month, while the comparison table lists $29, $79 and $250. Since yearly billing is advertised as saving 15%, the lower figures appear to reflect yearly billing; confirm the billing term at checkout. The core product can also be self-hosted for free, with a paid self-hosted Enterprise license available.

OpnForm publishes terms and conditions and a privacy policy. Form owners remain responsible for the personal data they collect from respondents.
