Open Source SurveyMonkey Alternatives

Feedback can be collected at any point in a user's journey with Formbricks, a survey and experience management platform. In-app, website, link and email surveys all come from the same tool, so a product team no longer needs one vendor for onboarding questions and another for a satisfaction email.

Surveys are assembled in a no-code editor with a range of question types and a library of best-practice templates. Targeting decides which user groups see a survey without any change to application code, and the results land in prebuilt analysis views or in whatever you choose to build on top.

The platform is meant to be extended as much as it is used.

• Survey types: in-app, website, link and email surveys managed side by side.
• Collaboration: organization members are invited in to work on surveys together.
• Integrations: Slack, Notion, Zapier and n8n among others.
• Familiar stack: TypeScript, Next.js, React, Tailwind CSS, Prisma, Auth.js and Zod, tested with Vitest.
• Self-hosting: Docker images run the whole platform on infrastructure you control.

The core is licensed under AGPLv3, is fully functional on its own, and may be used free for personal and commercial work as long as modifications are published under the same terms. Enterprise modules in the repository carry a separate license and need a key to unlock, and a hosted cloud version with a free plan suits anyone who would rather not operate it.

Running since 2006, LimeSurvey is an online survey platform used in more than 80 countries by businesses, academic institutions, teachers, students, governments and financial institutes. It covers the full cycle, from writing a questionnaire to analyzing what comes back, without a cap on surveys, questions or responses.

The editor carries more than 30 question types and over 900 templates, and surveys can be brought on brand with custom fonts, colors, logos, CSS and JavaScript. Skip logic and question branching decide what each respondent sees next, and a survey can run in more than 80 languages at once.

Beyond the editor, several capabilities matter for serious use.

• Distribution: share by public link, QR code or social post, or restrict a survey to invite-only personal links in closed access mode.
• Analysis: responses, statistics and data analysis tools, with export plugins for R and STATA XML.
• Integrations: SAML, LDAP, SURFconext, a REST API and RemoteControl over XML-RPC or JSON-RPC.
• Security: two-factor authentication, response anonymization and GDPR compliance.
• Accessibility: WCAG 2.0 compliance, which matters when a survey has to reach every respondent.

LimeSurvey is a self-hosted PHP application. It needs PHP 8.1.29 or newer with mbstring and PDO drivers, a PHP-ready web server such as Apache or nginx, and MySQL 8, MariaDB 10.3.38, PostgreSQL 14 or MSSQL 2019. The latest stable release is the recommended download, since the development repository may hold untested versions. The code is GPL v2.0 or later, and a hosted service exists for teams that want to skip the setup entirely.

Palform is a form builder whose entire codebase is public, marketing pages included, and whose responses are encrypted end to end. It keeps third-party scripts to a minimum and is free to use on the team's European servers, and the repository holds everything needed to operate the service.

Several Rust and JavaScript components make up the system. Rocket and SeaORM run the backend, Svelte runs the main app, and shared crates compile to WebAssembly for the frontend. The team chose Rust for stability rather than ease of feature work, and reports memory and CPU use close to nothing in practice.

The design choices worth knowing about are structural.

• Typed identifiers: database IDs are custom TSIDs with a per-resource prefix mapped to a Rust type, so passing the wrong kind of ID is caught in code.
• Generated bindings: TypeScript clients for the API come out of an OpenAPI generation step rather than being written by hand.
• WebAssembly modules: encryption and bulk analytics compile with wasm-pack because they run far faster than the JavaScript equivalents.
• PGP encryption: Sequoia handles form encryption and key management on both the backend and the frontend.
• Content sites: Astro and Svelte build the landing page while Docusaurus serves the blog and documentation.

Self-hosting is possible but not officially supported: there are no versioned releases yet, so the main branch carries no stability promise and no setup documentation. Contributions transfer copyright to the company behind the project, and the source is AGPL licensed.
