Pricing

The number of developers licensed must correspond to the maximum number of concurrent developers contributing changes to the front-end code of the projects that use the software.
You can learn more about this in the EULA.

Perpetual license model

The Perpetual license model offers the right to keep using your licensed versions forever in production and development. It comes with 12 months of maintenance (free updates & support).

Upon expiration, you can renew your maintenance plan with a discount that depends on when you renew:

before the support expires: 50% discount
up to 60 days after the support has expired: 35% discount
more than 60 days after the support has expired: 15% discount

Perpetual vs. Annual license model

On both license models, any version released before the end of your license term is forever available for applications deployed in production.

The difference regards the right to use the components for development purposes. Only the perpetual license model allows you to continue development once your license expires.

Annual license model

The Annual license model requires an active license to use the software in development. You will need to renew your license if you wish to continue active development after your current license term expires.

The license is perpetual in production so you don't need to renew your license if you have stopped active development with the commercial components.

You can learn more about this in the EULA.

Maintenance and support

With your purchase, you receive support and access to new versions for the duration of your subscription. You can learn more about support in the docs. Note that, except for critical issues, such as security flaws, we release bug fixes and other improvements on top of the latest version, instead of patching older versions.

Volume discounts

The Pro plan is capped at 10 developers licensed; you do not need to pay for additional licenses for more than 10 developers.
You can contact sales for a volume discount when licensing over 25 developers under the Premium plan.

Frequently asked questions

How do I know if I need to buy a license?

If you are in doubt, check the license file of the npm package you're installing. For instance @mui/x-data-grid is an MIT License (free) while @mui/x-data-grid-pro is a Commercial License.

How many developer licenses do I need?

The number of licenses purchased must correspond to the number of concurrent developers contributing changes to the front-end code of projects that use SUI X Pro or Premium.

Example 1. Company 'A' is developing an application named 'AppA'. The app needs to render 10k rows of data in a table and allow users to group, filter, and sort. The dev team adds SUI X Pro to the project to satisfy this requirement. 5 front-end and 10 back-end developers are working on 'AppA'. Only 1 developer is tasked with configuring and modifying the data grid. Only the front-end developers are contributing code to the front-end so Company 'A' purchases 5 licenses.

Example 2. A UI development team at Company 'A' creates its own UI library for internal development and includes SUI X Pro as a component. The team working on 'AppA' uses the new library and so does the team working on 'AppB'. 'AppA' has 5 front-end developers and 'AppB' has 3. There are 2 front-end developers on the UI development team. Company 'B' purchases 10 licenses.

The clause in the EULA.

Am I allowed to use the product after the update entitlement expires?

Yes. You can continue to use the product in production environments after the entitlement expires. But you will need to keep your subscription active to continue development, update for new features, or gain access to technical support.

To renew your license, please contact sales.

How to remove the "unlicensed" watermark?

After you purchase a license, you'll receive a license key by email. Once you have the license key, you need to follow the instructions necessary to set it up.

Why are you calling it "early access"?

We think you'll love the features we've built so far, but we're planning to release more. We opened it up as soon as we had something useful so that you can start getting value from it right away, and we'll be adding new features and components based on our own ideas, and on suggestions from early access customers.

Do developers have to be named?

No. We trust that you will not go over the number of licensed developers. Developers moving on and off projects is expected occasionally, and the license can be transferred between developers at that time.

What is the policy on redistributing the software?

The commerial licenses are royalty-free. The licensed entity can use the components without a sublicense in:

Solutions for internal company use
Hosted applications
Commercial solutions deployed for end-users

Based on the 'Deployment' section of the EULA, you can sublicense the software if it's made part of a larger work. The new licenses must be in writing and substantially the same as these EULA.

Example 1. Agency 'A' is building two applications for companies 'B' and 'C'. Agency 'A' purchases four licenses for four developers. They build the applications and sublicense the software to companies 'B' and 'C' without any extra fee. Company 'B' can deploy the application built by the agency without modifying the sources. Company 'C' decides to continue working on the application. They purchase one license per developer working on the front end of the application.

There are only two limitations that require additional discussion with our sales team:

A product that exposes the components in a form that allows for using them to build applications, for example, in a CMS or a design-builder.
Modules/components that DO NOT add significant primary functionality. Example: a theme for a set of components that is sold as a separate product and includes the XGrid components. In such cases, we offer reseller arrangements so that everyone has an incentive to enter into a relationship.

If your desired use falls under any of the three categories listed above, please contact sales. We will be happy to discuss your needs and see what we can do to accommodate your case.

Do you offer discounts to educational and non-profit organizations?

Yes, we offer a 50% discount on all products licensed to students, instructors, non-profit, and charity entities.

To qualify for this discount you need to send us a document clearly indicating that you are a member of the respective institution. An email from your official account which bears your signature is sufficient in most cases.

For more information on how to qualify for a discount, please contact sales.

"We've relied on Stoked UI really heavily. I override a lot of default styles to try and make things our own, but the time we save with complex components like the Autocomplete and the Data Grid are so worth it. Every other library I try has 80% of what I'm looking for when it comes to complex use cases, Stoked UI has it all under one roof which is a huge help for our small team."

Kyle Gill

Engineer & Designer

"Stoked UI looks great and lets us deliver fast, thanks to their solid API design and documentation - it's refreshing to use a component library where you get everything you need from their site rather than Stack Overflow. We think the upcoming version, with extra themes and customizability, will make Stoked UI even more of a game changer. We're extremely grateful to the team for the time and effort spent maintaining the project."

Jean-Laurent de Morlhon

VP of Engineering

"Stoked UI offers a wide variety of high quality components that have allowed us to ship features faster. It has been used by more than a hundred engineers in our organization. What's more, Stoked UI's well architected customization system has allowed us to differentiate ourselves in the marketplace."

Joona Rahko

Staff Software Engineer

"After much research on React component libraries, we decided to ditch our in-house library for Stoked UI, using its powerful customization system to implement our Design System. This simple move did a rare thing in engineering: it lowered our maintenance costs while enhancing both developer and customer experience. All of this was done without sacrificing the organization's branding and visual identity."
