Open-source forms.app alternatives

HeyForm is an open-source form builder aimed at small businesses and teams that need to collect information or feedback. It focuses on conversational forms, which cover surveys, quizzes and polls, and lets people build them without writing code.

Forms can use many input types, from text, email and phone number fields to picture choices, date pickers and file uploads. Conditional logic and URL redirects make forms adapt to answers. Integrations include webhooks, analytics and marketing tools, plus Zapier and Make.com. Themes control fonts, colors and backgrounds, and custom CSS allows deeper branding. Analytics report drop-off and completion rates, and results can be exported to CSV.

HeyForm is written in TypeScript and released under the AGPL-3.0 licence. The maintainers recommend their official hosted service for reliability, automatic backups and no maintenance, and the open-source code remains available for teams that prefer to run it themselves.

LimeSurvey is a free and open-source platform for creating online surveys and forms. Since 2006 it has been used by businesses, professionals, academic institutions, teachers, governments and others in more than 80 countries, and it is positioned as an alternative to SurveyMonkey, Typeform, Qualtrics and Google Forms.

Features include conditional logic, question branching, customizable templates and multilingual support, along with responsive design for different screens. The application is built mainly with PHP and JavaScript and works with MySQL, PostgreSQL and Microsoft SQL Server databases. The README links to a demo, documentation, forums and Discord, and invites feature requests and bug reports.

LimeSurvey's license is listed as 'Other' on GitHub, reflecting its GPL-based licensing. You can install it on your own server for full data control, or use the vendor's hosted cloud service. It suits researchers, institutions and companies that need privacy-conscious surveys with advanced logic.

FormsLab is an open-source tool for building surveys, polls and feedback forms. It can serve as a feedback app for collecting customer opinions, as a poll creator for voting, or as a general survey builder, and it sits in the same space as hosted form services such as Typeform.

Forms can include many types of questions, so layouts are not limited to a fixed template and can be made to look distinct. Surveys can be anonymous, which suits feedback gathering, and the project calls itself an experience management solution. The stack is TypeScript, Next.js, React, TailwindCSS, MongoDB, Prisma and Auth.js.

Developers can run it locally with npm commands for installing, running, testing and linting, and the project welcomes contributions. A live instance is linked from the README for trying it out. FormsLab is released under the MIT license.
