Open-source Checkbox alternatives

Formbricks is an open-source surveying and experience management platform, presented as an alternative to Qualtrics. It lets teams gather feedback at different points of the user journey through in-app, website, link and email surveys, and either use its prebuilt analysis features or build on top of it.

Surveys are created with a no-code editor that offers several question types and a set of ready-made templates. They can be targeted at specific user groups without changing application code, shared as links, and edited collaboratively by invited organization members. Integrations are available for Slack, Notion, Zapier, n8n and more, and the product is described as privacy-first.

The stack is TypeScript, Next.js, React, Tailwind CSS, Prisma and Auth.js. A hosted cloud version with a free plan is available, and the whole platform can also be self-hosted. The repository lists its licence as Other, so check the licence file for the exact terms before relying on it commercially.

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.

SurveyKing is an open-source platform for running surveys, graded exams and question-bank practice on your own infrastructure. It presents itself as a self-hosted alternative to SurveyMonkey, bringing content creation, publishing, responses, grading, analytics, users and permissions into one deployable system.

For surveys it offers responsive forms with many question types, conditional logic, themes and publishing controls, and forms can be created with AI, Excel, plain text, templates or a visual editor. Exams support reusable question banks, scoring, randomized content and automatic grading, while practice mode offers sequential, random and incorrect-answer drills with progress tracking, answer explanations, favorites and notes. Results can be analyzed by score, answer, ranking and question.

SurveyKing is written in Java with Spring Boot, licensed under MIT, and can be started with Docker using an embedded H2 database before moving to MySQL for production. The interface is available in several languages, including English and Simplified Chinese. It suits schools, training teams and businesses that want data ownership and survey features without a per-response subscription.
