FAQs – Ext JS Community Edition

What is Ext JS Community Edition?

A free, modern JavaScript framework for building data-rich, cross-platform web apps. Includes UI components, Material theme, npm tooling, and a limited-use commercial license—ideal for individuals and early-stage startups earning under $10K/year.

Who’s eligible?

  • Individuals: Free use until your revenue exceeds $10K/year.
  • Startups/Nonprofits: Teams with ≤5 developers and ≤$10K/year in revenue qualify.

Once you grow, upgrade to a commercial Pro or Enterprise license.

How do I get started?

Apply and register. If approved, you’ll get a 1-year license—free of charge.

Are other editions available?

Yes—Ext JS is available in Pro and Enterprise editions. Compare features

Can I upgrade later?

Absolutely. You can move to a commercial edition anytime and keep using all your existing projects.

Is a trial needed?

No. Community Edition is already free for one year. You can also request a 30-day trial of Enterprise if needed.

Can I sell apps/components built with it?

Yes. You can sell what you build—just upgrade to a commercial license once your annual revenue exceeds $10K. Please see license terms here.

Can I deploy apps internally at my company?

Yes, only if your total company revenue is under $10K/year. Otherwise, a commercial license is required.

Are there royalties?

No royalties required. Just upgrade when you pass the revenue or team size limit.

Can nonprofits use it?

Yes—if annual revenue is ≤$10K USD.

Can schools or students use it?

Yes. It’s great for students learning JS. For schools or academic use, contact us for educational discounts on commercial editions.

Why the 5-user team limit?

Community Edition is for small teams. Companies with more than 5 devs need commercial licenses.

How do I install it?

You will get access to our Sencha hosted npm repository to install Ext JS npm packages and tooling.

Can I sell my apps and components built with Community Edition?

Yes, and you’re welcome to. Remember that once you reach the $10,000 USD annual revenue limit (or local currency equivalent) we require you to purchase an Ext JS commercial license.
