Why SurveyJS
SurveyJS is your open-source alternative to mainstream SaaS survey platforms and pricey custom solutions.
Accessibility
Accessibility is a core focus for SurveyJS. Form Library (v2.1.0+) and Survey Creator (v2.2.2+) fully comply with WCAG, Section 508, and ARIA standards, verified using Axe®. Users can navigate with keyboards, use screen readers, and rely on proper ARIA attributes.
Unlimited Usage
SurveyJS has no usage limits. Create unlimited forms, collect any number of responses, and store all data in your database. No caps on admins, respondents, submissions, uploads, or features.
Custom Input Fields
Define custom standalone or composite question types and add them to the Toolbox. Extend built-ins or integrate Angular, React, or Vue 3 components to create advanced, reusable inputs and widgets.
Offline Data Collection
SurveyJS can work entirely offline. Surveys, themes, and responses are stored locally, so you can create, edit, and collect responses anywhere. When back online, data and updates sync automatically for a seamless local-first experience.
One-Time Purchase License
A one-time purchase developer licenses to use Survey Creator, PDF Generator, and Dashboard forever. No extra licenses for end users, multiple instances, or apps. Includes 12 months free maintenance and permanent rights to all versions released in that period.
Custom Data Validation
SurveyJS goes way beyond the basic built-in client-side validators. You can create custom client-side rules and implement server-side checks using JavaScript functions and event handlers.
Open-Source
All SurveyJS libraries are open-source and available on GitHub for React, Angular, Vue 3, and Vanilla JS. You can integrate, extend, and modify them while keeping all survey data self-hosted for full control over storage and privacy.
White-Labeling
SurveyJS gives you full control over the appearance of your forms and Survey Creator. Use built-in themes or create your own with CSS variables. You can export themes in JSON, set defaults, reuse multiple designs, and apply custom styles to individual form elements.
AI Assistance
Integrate AI via API to enhance form building. Enable natural language form generation, translation, or intelligent content suggestions. Users can prompt “Create a feedback form” to get a fully structured form with its JSON schema instantly.

SurveyJS provides all the building blocks needed to create your own form management system while retaining full control and ownership of your data. It allows even non-technical users to create an unlimited number of surveys and forms—both digital and PDF—collect responses, and visualize them using interactive charts and tables.
Secure Data Collection
The Form Library component lets you render interactive, dynamic forms in the browser. It’s MIT-licensed, lightweight, and animated. It supports basic and advanced question types, conditional logic, and validation, so you can guide users and collect accurate data.
Drag-and-Drop Form Creation
The Survey Creator component is a drag-and-drop form builder that produces JSONs for Form Library. It includes a rich Toolbox, a Theme Editor for form styling, and lets you apply advanced logic and branching, default values, and calculations—all without writing code.
Real-Time Data Reporting
The Dashboard component lets you view and analyze survey results in real time. It reads your form setup and then shows the data in interactive charts and tables. It also includes a Table View component for displaying responses in a data grid with options for client- or server-side pagination and filtering.
Export Your Web Forms to PDF
PDF Generator lets you turn your web forms into editable PDF files. It uses the form’s JSON schema, generated in Survey Creator, to reproduce the form’s layout and content. It can also fill PDFs with the responses you’ve collected, so you can easily create pre-filled, printable versions of your forms.
SurveyJS Helps Enterprises Keep Sensitive Data Secure
Whether you are from the education or healthcare sector, human resources, or anything in between—collecting sensitive data can become a maintenance nightmare, since you, as a survey creator, must guarantee anonymity and privacy to respondents (very often—to thousands of them) in order to remain legally compliant and ensure honest answers.
So the software you use to create and host surveys needs to be more than just a third-party, black-box SaaS platform where you’re locked in to too many dependencies, and locked out of engagement, monitoring, and improvement of the actual service because of intellectual property laws.
Even when surveys are conducted anonymously and with informed consent, you are not off the hook.
Even if you store only aggregated data, small sample sizes could inadvertently identify an individual, leading to adverse consequences. Also, most countries have laws governing the storage and security of collected data (HIPAA, FERPA, GDPR), meaning that you are liable for any stored personal information in your custody—including its secure destruction at the end of the retention period, with proof.
The easiest way to ensure individual privacy and legal compliance is to self-host SurveyJS. You would run surveys and store responses completely within your own infrastructure, thus being in total control of data flow between server and client without any third-party involved.
Self-hosting a SurveyJS solution grants you true freedom, and makes long-term planning not only possible, but also viable.

Frequently Asked Questions
What type of licensing model do you offer?
SurveyJS is free at the base and offers a perpetual developer-based licensing model for the Creator, PDF Generator and Dashboard libraries, meaning you can make a one-time payment and use the software indefinitely.
We provide access to the latest product versions and technical support on a subscription basis. A subscription lasts for a 12-month period (of the original purchase date, or of the latest renewal date). You get permanent access to the versions released within this period.
How do I decide on the number of licenses needed for my team? Do I purchase a license for each developer or is one per team sufficient?
We license our software development products on a per-developer basis.
You must purchase a commercial license(s) for software developer(s) who will be working with the SurveyJS products' APIs and implementing their integration.
You are not required to purchase developer licenses for your project colleagues that work on its different functional modules, and only use the libraries as dependencies to compile and build the project.
How does SurveyJS support integration with backend solutions and user management systems?
We do not offer backend solutions or data storage. SurveyJS provides and supports client-side JavaScript libraries for building surveys and forms, which can be integrated with any server or database of your choice. Our libraries are available for Angular, React, Vue3, and vanilla JavaScript, allowing you to fully control your backend and data.
SurveyJS does not access, store, or track any data. You will need to develop your own backend, and manage your data independently.
Additionally, if you need an approval mechanism—for instance, where one user creates a form and another reviews and approves it before publishing—this logic must be implemented on your server side. Our libraries provide the front-end UI and give you full flexibility to handle user authentication or management however you prefer. They work seamlessly with any backend logic you develop.
For backend integration examples, you can refer to our resources here:
This setup ensures you have full control over your data, user management, and server-side code, without any limitations from SurveyJS.
Am I allowed to use SurveyJS libraries in SaaS solutions?
YES. The license holder can deploy their license(s) to any web server or cloud for use in their web applications, including SaaS (Software as a Service) applications. However, such applications cannot compete with SurveyJS libraries (software development products) by offering a tool for developers to build their own form management system using the same codebase. Please refer to Paragraph 5 of the END-USER LICENSE AGREEMENT for further details.
Does the Enterprise plan come with unlimited developer licenses?
Our Enterprise plan is not unlimited—the cost is based on the number of developers who will be using the SurveyJS API and handling the integration. Pricing also depends on the specific libraries you require, whether it's just the Creator or a combination of Creator, Analytics, and PDF. It's important to note that we do not offer ready-to-use integration services directly. Therefore, you will need an in-house development team, and we will provide assistance during the implementation process. The Enterprise plan is ideal for those who require extensive consultation services, including code reviews, integration support, best practices, and urgent bug fixes. However, if you don't require those additional services and are comfortable receiving support through our Help Desk (available to all license holders), the Basic or PRO plan might be a better fit.
