Buy and Use with Confidence

The license is perpetual. You get permanent access to the version released in the first 12 months since your original purchase. A license renewal is optional and you can do it any time in the future. To continue to receive updates and technical support, you can renew the license for another 12 months and receive around 60% discount.

Our developer license is royalty free. We do not charge any royalties for redistribution of our libraries that have been integrated into your applications. We do not care how many applications you create using our libraries. As well, we do not care how many end users of SurveyJS Creator or SurveyJS Analytics Pack you have. This means that if you have dozens of millions of end users, then you are making great and cool apps and we are proud that you choose our software for your product(s).

A more accurate license-related question that you need to ask yourself is: How many software developers in my company/team are going to work with SurveyJS product APIs, integrate them into your applications, write components and so on? The answer to this question will give you the correct number of licenses to purchase.

Note that it is implied that your users are exactly end users - they are not application developers by themselves and they do not use the API of our libraries to create/modify their own applications. In case you create software for software developers, please contact us to make an OEM agreement between our and your companies to license such developers.

To transfer a license, you need to send a recipient's email address to info@devsoftbaltic.com. We ordinarily do the transfer in the same day. Note that the recipient should be registered within our system using the provided email address.

You require to purchase the developer license(s) anyway. The most of our paid customers use our libraries in internal web applications, intranets and websites. If you are from a non-profit organization, then please contact us and we will arrange a license for you.

The idea of our project is to allow other companies to get rid of using third-party survey services and create their own survey app/service. If you use our libraries in your web applications, then we do not touch your data unless you take some extra actions and write specific code allowing this. By default, we do not have access to your data.

We do not have any intention to get your data and we prefer not to. The only information that we need to store is the information needed to create the invoice and minimum information about your software developers to arrange licenses for them in our system.

We do have our own survey cloud. It is free. We created it as an example that demonstrates what can be done with our client libraries. It allows you to start and test the functionality of our libraries quickly, without creating your own services and databases.

You can try our libraries before a purchase. We allow you to purchase our software after you make certain that it works as needed.

All our libraries are open source software. You can find our source code on GitHub. Please select a library-related repository to get the library's source code and development history. In repositiries, use the Issues tab to track our progress in fixing bugs and implementing new functionality.

Absolutely. You can fork our GitHub repository and make the required changes. However, we strongly recommend that you contact us about the functionality you want to introduce. Probably, this functionality might be already implemented or we might be going to introduce it in the short term. And we always are open to work together on any required functionality.

We constantly improve our libraries. We are trying to keep the number of bugs at the minimum possible level and to fix open issues before starting to work on any new functionality. We understand the importance of having bug-free libraries. Being big fans of test-driven development (TDD), we massively write unit tests to reproduce bugs at early development stages and to be able to fix issues as soon as possible.

Since we have a lot of unit tests, functional (E2E) tests and CI setup, we can introduce new minor (but useful) updates every week.

Regarding new functionality - the short answer is yes, we do add new features. However, it depends. Every new functionality/feature has its value and cost. By value, we mean how useful it is for our customers. How many users are going to use it? Is it crucial for them to have it? By cost, we mean developer hours, the possibility of breaking changes, the harmfulness of breaking change if any introduced. We do not like breaking changes, nobody likes them. As an illustration - our Survey JSON definition exists from the first beta and still works perfectly in the current version. So, if a feature's value/cost rate is high, we will likely introduce the feature. The bigger the rate is, the sooner we will work on the feature. And, on the contrary, if the value/cost rate is low, then we will unlikely introduce the functionality in the near future, probably never.
