Vaadin licensing FAQ and troubleshooting

Premium CI/CD

Go to the license management and download your server license key and follow the provided instructions.

Premium CI/CD Offline

Go to the license management and download your server license key and follow the provided instructions.

Premium Administration

First, check if your application is compiled with daily active user tracking enabled. Search for “Daily Active User tracking enabled” log statement (INFO level) in your build logs.

Second, double check you are using the subscription key that matches your subscription. You can find your subscription key in the license management.

Third, make sure that the correct application is deployed.

Trial Premium CI/CD Subscription Offline

This means that you either

1. did not provide a valid license key during build time,
2. the product is not part of your subscription or
3. the license checker could not verify your license for other reasons

First, check if the commercial product is actually part of your subscription.
Second, verify if your API key (proKey) exists or offline key is up to date. In case of CI/CD build verify the server license key is valid.
Sometimes company firewalls block requests to tools.vaadin.com or maven.vaadin.com. Either ask your administrator to open the firewall or set up a local Maven repository and use offline keys.

Premium Administration

Go to the subscription management view and add your email address to the list of “Alert email addresses”. Our customer service team is also always aware of the situation and will contact you in case of incidents.

Premium Administration

First of all: No, your application will not stop working. But the license server noticed that the number of daily active users of your applications exceeded the negotiated limit at least once. The next step is to check your subscription state and prove if this was a one-time event or if the number of daily active users increased over time and finally hit the limit. In case of a one-time event like a sudden peak in users we recommend monitoring the tracking statistics for the next few days.
In the second case we recommend contacting your sales contact or customer support at Vaadin to discuss the situation.

Premium

Yes but not immediately! This only happens if either we cannot get in contact with you so that we cannot negotiate new limits or if the negotiations failed. In both cases the DAU limit will be enforced after the grace period ends. Your application will still be usable but will block users when the limit is hit.

Premium Administration

Daily Active User represents a human end-user for one application that you built with Vaadin and run in production mode, during a 24-hour period.

This includes anonymous users or authenticated users but also test users for integration testing if they interact with the application for at least a minute. Just visiting a view and closing the browser will not be counted as DAU.

Check our documentation for instructions on how to optimize your DAU counting.

Premium Administration

Yes and no. We cannot differentiate between bots and human users easily. But you can configure a set of application names to prevent counting users of them.

Subscription Trial

First, check your subscription state and if the license validation works. If not, either your company's license administrator has not yet assigned a seat for you, or the license is no longer valid.

Premium Subscription Administration

Account owners or administrators can reassign the seat to someone else in licence management or contact customer.support@vaadin.com.

Premium CI/CD Subscription Offline

The licenses for commercial components are checked through your vaadin.com login. The first time you are using a commercial product, it will ask you to log in to vaadin.com to validate your license. You only need to manually install the license key when running on a CI/build server or when you want to work offline.

Premium Subscription Vaadin 7/8 Offline

Vaadin provides offline license keys that allow development in environments where online access is not possible or disallowed.

Subscription Vaadin 7/8 CI/CD

Go to the license management and download your server license key and follow the provided instructions.

Vaadin 7/8 Subscription

Extended Maintenance

When using the latest Extended Maintenance releases the new license checker version is used for the framework product itself. This applies to versions Vaadin 7.7.17 and newer, Vaadin 8.14.3 and newer respectively. Follow the same guidance as described in https://vaadin.com/myaccount/licenses#latest

Furthermore from version 7.7.37 and respectively 8.20.2 the widgetset compilation phase has been updated to use the new license checker as well. Hence Charts, Spreadsheet, Touchkit or Board will no longer require specific license key. The server / offline key is used instead.

Additionally TestBench version 5.3.0 and newer uses the new license checker.

When using Designer with Vaadin 7 or 8, or TestBench 4 with Vaadin 7 the old product specific keys are used, see the next chapter.

Older versions

Vaadin 6/7/8 license check is done through license keys. Please find your license keys from https://vaadin.com/pro/licenses. Click on a license key to obtain the purchased key. Note: a new set of keys will be generated with every subscription renewal.

To install the license key in a development workstation, you can copy and paste it verbatim to a file in your home directory

License for each product has a separate license file as follows:

Vaadin Charts
.vaadin.charts.developer.license

Vaadin Spreadsheet
.vaadin.spreadsheet.developer.license

Vaadin TestBench
.vaadin.testbench.developer.license

You can also pass the key as a system property to the widget set compiler, usually with a -D option. For example, on the command-line:

java -Dvaadin.<product>.developer.license=L1cen5e-c0de …​

Please contact license@vaadin.com and we can help you further.

Premium Subscription Trial

Clear Vaadin cookies and try again.

Please make sure that you use the same window.

Adblocker or 3rd party cookie denial could be blocking the license check. However, the error message only appears in development mode when in localhost. When the application is deployed into production and accessed from outside it will not show, thus the message will not visible to the end users of the application.

Core

If you want to be certain you're not using anything commercial, then you can change the main dependency to vaadin-core instead of vaadin in your pom.xml or build.gradle file.

Student

Please apply again for the student program. If the problem continues, please contact us in the Vaadin Forum channel.

Subscription Vaadin 7/8

Previously it was possible to either buy a Pro subscription, or purchase a single license for a specific major version of a product. From Vaadin 10 onwards, we have decided to discontinue the single licenses. In order to use Designer after the trial period, a valid Pro subscription is required. Please see vaadin.com/pricing.

Premium Subscription Administration

License can be assigned only by either the company's license owner or administrator.
In case you are a license owner or administrator you can assign licenses to developers in the team management view.

Depending on your build tool you either have a

a) pom.xml file (Maven)

Look for a vaadin.version property there. If you can’t find the property, check if there is

• a vaadin-bom dependency. Its version is the Vaadin version.
• a vaadin-server dependency. Its version is the Vaadin version.

b) build.gradle file (Gradle)

There is a vaadin { block that has the version number.

c) ivy.xml file (Ivy)

There is something like <!ENTITY vaadin.version "7.6.5"> which shows the version.

Yes, running applications and also application restarts are not affected. The license checking mechanism will continue polling our servers but with increased timeouts.
