Developer Express does not charge any royalties for redistribution of components that have been integrated into applications which you engineer. Of course, this only applies if you have a valid license to all products which are being used within your application.
Important Note: DevExpress engineers products that include "redistributables" and those that do not. Our EULAs fully outline whether a product includes redistributables and the terms under which redistribution is authorized.
Please refer to the following pages to see all available product subscriptions, their features and pricing information:
All DevExpress products are sold based on a subscription model. This means that when you purchase a Subscription, you receive 12 months of free updates for that product(s) from the date of purchase - be it a minor service update or a major new version. After the 12 month period and at your discretion, you can pay about 45% of original price to "renew" the subscription and receive another 12 months of free updates. If you choose not to renew, you can continue using the last version you obtained or are eligible to use. The 12 month time frame is merely for new versions/updates and does not apply to rights of use (as long as the EULA is not violated).
Note that you can renew a subscription after it has expired. Renewal costs increase 30 days after expiration of your subscription (pricing increases on a monthly basis after the 13th month). Please contact a member of our Client Services team if you have an expired subscription or if you need further clarification on the terms of our subscriptions.
When you purchase a training course, you receive 12 months of unlimited training content access from the date of purchase. You need to purchase a license per each individual developer. Multiple-seat discounts are available starting with two licenses.
If required, you can purchase a training class subscription again after the 12 month period has expired.
Absolutely. You can continue to use products which you have licensed and paid for...as long as you require. When a subscription expires, it simply means that you will no longer be issued any product updates or new product releases.
An expired subscription can be renewed. If you do not renew your subscription on the 13th month after purchase, your renewal cost will increase on a monthly basis. Feel free to contact a member of our Client Services team for more information on renewals and product costs once your subscription expires.
Yes, section 5 of our EULA defines the terms of license transfers. In order to transfer a license from one business to another, you will need to request the change in writing. The request must come from the original purchaser or from an officer of the company. License transfers shall only be granted if the original software project(s)/and or software product(s) your organization developed are also being transferred to the new business entity. If you are not transferring the rights to the software project(s)/and or software product(s) you created using DevExpress components, controls and libraries, the license transfer will not be granted. In case of the latter, the new business entity will need to purchase a new license in order to continue the use of our tools.
If you wish to initiate a license transfer, please contact a member of the DevExpress Client Services team. The following is a sample letter you can use to request a license transfer:
To Developer Express Inc.
I, ________________, President of <current company name> do hereby request that Developer Express Inc transfer all DevExpress SOFTWARE COMPONENT PRODUCT(S) currently owned by <current company name>
to <new company name>. I understand that all rights outlined in the Developer Express Inc End User License Agreement will be transferred to <new company name> and that <current company name> shall no longer have the right to redistribute Developer Express intellectual property or any SOFTWARE COMPONENT PRODUCT(S) REDISTRIBUTABLES as defined in the End User License Agreement.
<current company name>
Yes. Each developer that uses our products must have their own license. We don't license per machine, per server, or demand any royalties or run-time fees. For more information, refer to our End-User License Agreement. If you have a testing team and they need to compile the application, then those testers will also each need a license. Testers who just test the completed, compiled application (that is, use it much as an end-user does) do not need a license.
Yes. In fact you can do this yourself using our website once the company has purchased multiple licenses. Log in to the DevExpress website and select My Account | Manage & Assign Licenses where you can assign a particular license to a given email address (that's how we differentiate between developers). You also assign a password at the same time. Please note that we do not allow any type of floating licenses. For more information, refer to our End-User License Agreement.
To a certain extent. The EULA specifically states two, but to be honest we don't worry unless there's obvious piracy going on.
If no development is performed on the build machine and its sole purpose is to generate actual builds of your products, then no you do not need to purchase a separate license for the build machine. If however a developer uses the build machine for active development and this developer does not have a valid license for the products, then yes, he or she must acquire a license for the product.
Since a developer can install on several machines (see the previous answer), get a senior developer to install his license on the build machine. If you like, he becomes the "owner" of the product on that machine.
You do not need to install our products on deployment servers. If you've purchased a license, you can simply deploy the appropriate DevExpress runtime libraries with your application.
No. The only information required to activate (actually, that should be "to install") is the email address and password associated with the license.
Yes, however validation is still required. If the machine being activated is not connected to the internet, our installer displays an opaque data blob that should be sent to us (presumably on another machine), and we reply immediately with another opaque data blob that must be entered into the installer. Once that validation has checked out, the installer will proceed to install the product. The installer will tell you what to do and how to do it.
Like all software you purchase, we do not provide any warranty. In essence, we provide the software "as is". To be absolutely sure of what we do or do not provide, please refer to the EULA.
However, when you purchase a license, you will have access to all upgrades updates and support for a full year. An expired subscription can be renewed. If you do not renew your subscription on the 13th month after purchase, your renewal cost will increase on a monthly basis. Feel free to contact a member of our Client Services team for more information on renewals and product costs once your subscription expires.
Absolutely. You can modify our source code and redistribute the modified libraries. As you can imagine, this does not apply to situations in which you are modifying our code, repackaging our controls and selling competing controls. Please consult our EULA for additional information.
No, the source code is not redistributable, even if you change it. The only files you may distribute are explicitly listed in the EULA.
Support is provided by one of two methods: either by a web-based system we call the Support Center, or by email (firstname.lastname@example.org). We aim to respond to all questions within one business day. Support via phone, IM, or chat is not provided. The support team may, in certain circumstances, decide to access your development machine using Remote Desktop or similar. This is determined on a case-by-case basis.
Support is only provided to a developer with a valid license.
Delivery of our products is by download only. We provide 2 major releases of our products a year, with about 3 - 5 minor releases in between. We notify customers via email when a new release is ready for download. When necessary, we publish hotfixes that can be downloaded from the DevExpress Support Center.
DevExpress licenses its software components and development technologies on a subscription basis. The subscription duration is 12 months from the date of purchase. If your subscription is active, you can download and use updates, service packs and hotfixes for all products included in your subscription. Upon expiration of a subscription, you can optionally renew your license for an additional 12 months and receive another year of updates from DevExpress. If you do not renew your subscription, you may continue to use the products you’ve licensed but you will no longer receive new updates or be eligible for technical support services from DevExpress.
If you have questions or need more information on our subscription plans, feel free to contact a member of the DevExpress Client Services Team by Email or by phone at +1 (818) 844-3383 between 7:30AM and 4:30PM Pacific Time.
There are no general rules here: it really depends on the severity of the issue, whether there is a temporary workaround, etc. In most cases, you will be able to get a hotfix from support, or from the issue page in the Support Center. Sometimes, there's no possibility of a hotfix and you will have to wait for the next minor release. Since we publish releases every three weeks or so on average, it's unlikely you'll have to wait very long.
No, there is no such premium level of support. We endeavor to fix critical bugs (that is, those without a viable workaround or those visible to many customers) as soon as possible.
No, I'm afraid there isn't. We do not incorporate other people's code into our own because there are too many legal ramifications. To be honest we prefer implementing the solution to a given issue/suggestion ourselves rather than pay legal fees to cover those ramifications. We are, after all, developers - it says so in our company name.
If you are targeting .NET, then DXperience and Universal Subscriptions contain the entire source for the controls for all platforms (DevExpress does not ship source code for CodeRush and Report Server). Other .NET subscriptions ship without the source code.
All VCL subscriptions are available with full source code.
Yes, of course you can change the source. However, you would be then responsible for applying the same changes to the source every time we release a new minor/major version (and there could be upwards of 15 releases a year). Sometimes, we may rewrite or refactor our code such that it's no longer obvious how to apply your previous changes. Depending on how extensive your changes are, we might not be able to provide support.
You cannot circumvent our license agreement by providing non-licensed developers with controls you've altered by changing the source. Again, read the EULA to determine what you can or cannot do in this respect.
Obviously, we will not provide our signing keys for any assemblies you modify, so be aware of possible "DLL hell" problems that could occur on end-user machines if they have several apps from different vendors that use our controls.
