Does Flexmonster require an Internet connection to work correctly?

No. Flexmonster does not require Internet access to work properly.

The only requirement is that Flexmonster needs to have access to the data source you specify. The data source can be remote or in the local network. Other operations, including the license key validation, are handled without access to the Internet.

How often do you release updates?

New minor versions are released biweekly. Follow our release notes to learn about the latest updates.

Note We recommend updating Flexmonster regularly to get bug fixes and access new features. See how to update Flexmonster to the latest version.


Does Flexmonster send any data to external servers?

No. Flexmonster does not send any data to external servers. Most operations, including the license key validation, are performed on the client's machine.

Depending on a data source, Flexmonster can make requests to fetch the data from the specified location, for example, from your own endpoint. All such requests can be observed in the "Network" tab of the browser's developer console.

How do you ensure security when connecting to OLAP cubes?

We offer a special server-side tool - Flexmonster Accelerator for OLAP cubes. It adds additional security to your data and allows you to restrict any external access. You can read all the details about security concepts in our documentation.

How do you ensure security when connecting to databases?

We offer a special server-side tool - Flexmonster Data Server. It allows managing security and establishing authorized access to the data. Follow our detailed guide on configuring security and authorization in the Data Server.

Can I connect to an SQL database directly?

Direct connection from the browser to the database is not secure, so it is not supported in Flexmonster.

To address this, we suggest using Flexmonster Data Server. This server-side tool allows you to manage the data access and security the way you want.

The Data Server supports MySQL, Microsoft SQL Server, Microsoft Azure SQL, PostgreSQL, and Oracle databases. We have a detailed tutorial for each database.

Is it possible to connect to my OLAP cube using the XMLA protocol?

Flexmonster supports connection to OLAP cubes via the XMLA protocol. However, XMLA is difficult to configure and often works slowly. To increase data loading speeds, our team created Flexmonster Accelerator.

This server-side utility ensures security and allows you to restrict any external access to the data. Learn more about configuring the authentication process in Flexmonster Accelerator.

Which licenses do you offer?

We offer four license models. Our licenses cover different cases of Flexmonster use:

  • Single Corporate License (annual/perpetual). Under this license, Flexmonster can be used by the employees of one company for internal purposes only.
  • SaaS (annual). Under this license, you can embed Flexmonster in your cloud platform that is accessed by multiple customers.
    The SaaS license is perfect for situations when your application is hosted on one main domain, and each of your customers uses a separate subdomain to access it:,, etc.
    If you have custom domains mapped to your SaaS application, please check this page for more details.
  • OEM (perpetual). Under this license, you can distribute your application with Flexmonster to multiple customers (e.g., 3, 5, 10, 50).
    This license is perfect for situations when your application is deployed on multiple domains:,, etc. You would need one license from the bundle to cover one client.
  • Unlimited Distribution (perpetual). This is the most comprehensive license. It gives you the freedom to embed Flexmonster in your application and deploy it however you want, from on-premises environments (i.e., OEM deployment) to cloud and multitenant platforms (i.e., SaaS deployment).

All licenses include everything you need to use Flexmonster: deployment in production and pre-production (dev/test/QA) environments, availability for an unlimited number of developers, unlimited technical support, and access to the latest updates.

What is the difference between annual and perpetual licenses?

An annual license is valid for one year after purchase. It also includes one year of maintenance (support and updates). After the license expires, you need to renew it to continue using Flexmonster.

A perpetual license has no expiration date, and the component will not stop working. However, the license maintenance is annual. For more details, see What happens when the maintenance of my perpetual license expires?

License keys

How do I request a key?

To request a license key, please contact our Sales team. Make sure your request contains:

  • Fully qualified domain name (everything between http:// or https:// and the first slash) or an IP address.
  • Type of environment for each key (production, staging, testing, development, etc.).

What information is embedded into my license key?

Each license key contains information about the domain name, expiration date, and maintenance duration. With your specific license key, Flexmonster can be used only on your specific domain.

How can I check the license key I'm using?

Click on the grid and press Ctrl + Alt + i (Option + Control + i on macOS). You will see a pop-up window with your license key.

What if somebody copies my license key and tries to use it elsewhere?

A license key is always tied to your domain and will not work with any other domain.

Do I need separate keys for production and development environments?

Yes. With your development key, the component can be run locally on your computer (localhost) or on a server using the server’s IP address. To use Flexmonster in a production environment, contact our Sales team and request a production key.

Learn more about license keys types in our documentation: Managing license keys.

How can I update my license key?

When you receive a new license key from us, replace your old key with the new one by following this guide: Setting a license key.

To ensure the key was updated, click on the grid and press Ctrl + Alt + i (Option + Control + i on macOS).


What happens when my license expires?

If your annual license expires, the component stops working. You need to renew the license for another year to continue using Flexmonster.

If you have a perpetual license, the component will not stop working.

How can I renew my annual license?

You can renew it by getting a new annual license on the website or by requesting an invoice from the Sales team.

What happens when the maintenance of my perpetual license expires?

After the maintenance period is over, the component continues to work. However, you can no longer update Flexmonster and receive technical support from our team.

To prolong access to updates and support, please renew the maintenance for another year.

How can I renew my license maintenance?

To renew annual maintenance, please request a quote/invoice from the Sales team.

I missed the renewal of my annual maintenance. Can I renew again later?

Yes. You can renew the maintenance anytime after its expiration. Please contact our Sales team for more details.

What is the difference between renewing the annual maintenance for a perpetual license and getting an annual subscription?

  • If you renew the annual maintenance of your perpetual license, the updates you get throughout that year can be kept perpetually with your license.
  • If you get an annual subscription, you can use the component and receive updates only during the subscription period. Afterward, the license stops running.
  • If you have a perpetual license and decide to get an annual subscription, it is considered a separate license. You would not be able to keep the updates from the annual subscription with your perpetual license.

Why do we need to change keys if we have a perpetual license?

When you have a perpetual license, your license key does not have an expiration date. However, the key has embedded information about the maintenance expiration date. After this date, you won’t be able to update the component. So, you need a new key to be able to update Flexmonster.
