OpnForm

OpnForm is an open-source online form builder with unlimited submissions. It’s designed for creating contact forms, surveys, application forms, and simple landing-page forms without coding.

Build forms fast, no code

Create a form in minutes by choosing field types, adding images, and setting up question flow. The interface is geared toward speed so you can publish quickly and start collecting responses.

Flexible fields and conditional logic

OpnForm includes more than ten field types and supports conditional rules that change what respondents see based on their answers. This works well for:

• Surveys and questionnaires
• Multi-step application flows
• Forms that adapt to different user paths

Unlimited responses and data control

OpnForm doesn’t limit the number of forms, fields, or responses. You can share forms via a link or embed them on your website. It also supports integrations with external tools to pass data to CRM systems, email, or analytics. The project is fully open-source, with code available on GitHub, which helps teams that need transparency, customization, or self-hosting.
