General Public License v2.0

RGraph is available to use under a dual-licensing scheme. You can use it as you wish under the terms of the GPL (General Public License). Alternatively you can purchase an RGraph non-GPL License, use it under those terms and not be bound by the GPL restrictions (eg affecting the licensing of your own application; modifications should be shared with the original author).

 

If you use it under the terms of the GPL please link back to this website, thanks.

Donations

RGraph doesn't make much money from the non-GPL licensing, so if you use it under the GPL and want to say "thanks for all your hard work" then you can make a donation to the project (which really helps when it comes to things like paying rent!) by using the Paypal donate button here. Thanks in advance if you choose to do so. Keeping a roof over my head and having a constant electricity supply is a big advantage in programming!




Non-GPL licensing

 

Single website license: £99

The Single website license covers an entire website that cannot be described as dynamic. It covers an unlimited amount of developers and you can edit and/or update the code as much as you want to.

 

Five developer license: £199

The 5 developer license covers 5 developers in your organisation to work with RGraph. Anyone who works either directly or indirectly is considered a developer. You can edit and/or update the code as much as you want to.

 

OEM license: £499

The OEM license allows you to include RGraph in your own software which may be used for the purposes of building websites or related materials and you would prefer your Customers not to incur any further costs as a result of using RGraph; or a similar situation where your software contains RGraph and you don't wish your users to be liable for their own RGraph non-GPL license. In this case the OEM license is 499. You can use the "Buy now..." button above to purchase this license type.

OEM License terms

  1. You are granted the non-exclusive rights set forth in this document provided you agree to and comply with any and all conditions in these terms.
  2. You may develop application programs, reusable components and other software items that use the original or modified versions of the RGraph software. You may include RGraph as a part of the software that either supports or controls the software or device(s) that you make.
  3. The OEM license permits you to use RGraph as part of your own software or hardware which may or may not then be used by your own Customers to build web sites, web applications, web based software or non-web based software. As a result of using your software or hardware your Customers do not have any further responsibility to purchase their own RGraph non-GPL License.
  4. The OEM license can also be the most economical way of licensing a large number of your clients. If you do have a large number of clients who use your product(s) (which may or may not be on different domains) then instead of buying a license for each Customer you can instead buy an OEM license which will cover all current and future usage. The OEM license is a one-time payment of £499.
  5. You may use the RGraph name in your promotional materials if you wish to promote your software or hardware. The RGraph name must not be used in a derogatory, defamatory or negative way or in a way that would bring RGraph into disrepute. You may not sell/resell or purport to sell/resell RGraph non-GPL licenses or do anything which may cause harm to RGraph non-GPL Licensing sales. The OEM license is for you and Customers who buy your products or services only.
  6. You may not sell, resell or otherwise provide RGraph as an independent piece of software. You may include RGraph as part of your own software, hardware or as part of the service(s) that you provide but you may not sell/resell RGraph or purport to sell/resell RGraph non-GPL licenses

Non-GPL licensing FAQs

Do I need to buy a non-GPL license?
For non-GPL use, then yes - you need to purchase a non-GPL license to use RGraph. Otherwise - you may use RGraph in compliance with the terms of the GPL.

How many licenses do I need?
This depends on the type of license that you buy. For the Single website type of license you should have one per website. For the 5 developer license your usage of RGraph is not restricted by websites - just the number of developers that use RGraph. And with the OEM license there are no limits on the number of websites that you can use it on or developers that can make use of it.

How much is a non-GPL license?
The price for a Single website RGraph non-GPL license is 99. The 5 developer license is 199 and the OEM license is 499.

Is the fee recurring or a single payment?
The RGraph non-GPL licensing fee is a single one-time payment and does not recur.

Where can I buy RGraph non-GPL licenses?
The only place you can buy RGraph non-GPL licenses is this website.

How much does support cost?

To enquire about the discount please email support.

What if I need something that's not part of RGraph?
If there's a feature that you need that's not part of RGraph then please get in touch with the RGraph support team. If it's not too specific then it will most likely be able to be added to the general distribution of RGraph.

What does the license cover?
The RGraph license covers RGraph as a whole. The (RGraph) JavaScript code that you find in the archive is covered by the RGraph license (ie the GPL or the non-GPL license).

What if I make an authoring tool (or similar) that I wish to include RGraph with? (OEM licensing)
If you make an authoring tool that you wish to include RGraph with then you're free to do so. Keep in mind though that any users who make use of RGraph will become susceptible to the GPL or be liable for their own RGraph non-GPL license. If you don't wish for this to happen then you can instead opt for an RGraph non-GPL OEM license for your software. This will mean that you and your softwares users can use RGraph and not have to worry about RGraph licenses. You can use the button above to buy the OEM license.

Do I need to provide a backlink?
Anybody who uses RGraph under the non-GPL licensing does not need to link back to the RGraph website. If you're using the software under the GPL please link back to the RGraph website. You can find details on providing a link to the RGraph website on the backlink page.

Can I get an invoice?
Simply go here to create an invoice: http://www.rgraph.net/invoice, enter your email address and you can create and print an invoice that you can use for tax purposes.
