Here are some good open-source form builders you can use, depending on what you need:
Popular options
- Form.io — powerful, enterprise-friendly, JSON-based forms, workflows, API-driven.
- BudiBase — open-source no-code platform that can build forms and internal tools.
- Formbricks — open-source survey/form tooling, great for feedback forms and in-app surveys.
- Tally alternative: OhMyForm — simple open-source form builder.
- Typebot — more conversational forms / chat-style flows.
If you want self-hosted drag-and-drop form builders
- Form.io
- OhMyForm
- BudiBase
- Caldera Forms (WordPress ecosystem, legacy-ish)
- SurveyJS (open-source library, not a full builder UI by itself)
Good choices by use case
- Simple public forms: OhMyForm, Formbricks
- Complex workflows / integrations: Form.io
- Internal tools + forms: BudiBase
- Chat-style forms: Typebot
Things to check before choosing
- Self-hosting support

- Conditional logic
- File uploads
