These changes reflect the feedback we’ve gathered from long-term users and our ongoing efforts to keep Jmix sustainable and aligned with real-world development needs.

The new structure improves clarity across tiers, lowers the entry barrier for advanced features, and better separates distinct use cases like process automation.

## What’s Changing — and Why

1. **“Free” becomes “Community”**
We’re renaming the Free plan to **Community**. This name better reflects the open-source nature of Jmix and the tools shared across the entire developer base. No changes to features or access.

2. **“RAD” becomes “Sprint”**
While RAD served its purpose for many years, we’re renaming it to **Sprint** to better reflect how most teams work today — fast, structured, and iterative. The feature set remains unchanged.

3. **«Enterprise» becomes more focused and accessible**
With BPM functionality now separated, the Enterprise plan is focused entirely on enterprise-grade development features such as **Maps**, **Kanban**, **WebDAV**, **Notifications**, and **UI Constraints**. Following this restructuring, the plan will be priced **25% lower for companies** and **30% lower for individual developers**.

4. **«BPM» becomes a standalone plan**
Process automation is a distinct application layer with its own architectural and operational needs. To better serve those use cases, we’ve moved all BPM-related functionality — including the engine, process forms, task panel, and admin tools — into a dedicated **BPM plan**, offered at the same pricing level as the former Enterprise tier.

## A Note on Pricing Context

Earlier this year, in **January 2025**, we introduced a moderate price adjustment to reflect platform growth and operating costs. **At that time**, the Enterprise tier included BPM and other advanced tools in a single bundle.

With the July restructuring, we’ve realigned each tier to specific use cases. As a result, the Enterprise plan has a narrower focus, and its pricing has been revised accordingly. These changes are not simply discounts, but a reflection of the updated scope of each plan.

## How These Changes Affect Existing Users

– **Free (now Community)** continue to have full access to Jmix’s open-source core — now under a name that better represents its purpose.
– **RAD (new Sprint) monthly subscribers** will see only a name change. Pricing and access remain unchanged.
– **RAD (new Sprint) annual subscribers** will be automatically moved to the new Enterprise plan and will retain their current RAD pricing until **July 1st, 2027**. This includes full access to all Enterprise features (excluding BPM), including upcoming add-ons like Group Data Grid (coming Fall 2025) and Tabbed Application Mode.
– **After the 2-year transition period**, these users will have the option to continue with **Enterprise at the standard rate**, or return to the **Sprint** plan.
– **Enterprise subscribers** will be upgraded to the new **BPM plan** automatically. No action is needed. Access to all BPM features will continue uninterrupted and pricing remains the same.

## Looking Ahead

These updates are part of our continued effort to keep Jmix competitive, sustainable, and aligned with the needs of Java teams building complex enterprise software. The clearer tier structure also allows us to deliver new features faster and more predictably across the platform.

We remain committed to helping you build and ship high-quality software — faster, with less overhead, and with tools that match the scale of your team.

**Jmix — Develop smart, not hard!**

This article shares the story of Ondrej, a senior Java developer, who accelerated full-stack development using Jmix.In the world of software development, finding tools that simplify the process without sacrificing functionality is a game-changer. Ondrej, a seasoned Java developer with over 20 years of experience, shares his journey of discovering Jmix and how it transformed his approach to building full-stack applications. His story highlights the challenges of traditional development and the advantages of adopting Jmix for solo developers and teams alike.

The Challenges of Traditional Full-Stack Development

Ondrej’s career has been deeply rooted in Java, with extensive experience in both back-end and front-end technologies like React and Angular. However, he often faced significant hurdles when working on full-stack projects, especially as a solo developer or in small teams.

– **Complexity**: Managing separate front-end and back-end stacks required extensive effort, from business analysis to deployment.
– **Resource Constraints**: As a freelancer for the Czech Academy of Sciences, Ondrej often worked alone on administrative applications, where hiring additional help was impractical due to bureaucratic limitations.
– **Time-Consuming Processes**: Older frameworks like GWT, which initially simplified his workflow, became obsolete and introduced slow build times (up to 5 hours for transpilation).


These challenges led Ondrej to seek a more efficient solution — one that would allow him to focus on business logic rather than juggling multiple technologies.

Discovering Jmix: A Turning Point

Ondrej was actively looking for a framework that would let him build full-stack applications using only Java. When he discovered Jmix, its modern approach and developer-centric features immediately caught his attention — it looked like the tool he’d been searching for.

Key Benefits He Experienced:

1. **Unified Development**: Jmix’s back-end-driven approach eliminated the need to worry about front-end security and state management, as the client side is inherently trusted.
2. **Rapid Prototyping**: Using Jmix’s Figma component library, Ondrej could quickly create mock-ups and iterate with stakeholders before diving into development.
3. **Speed of Development**: Building CRUD views and configurable applications became significantly faster, allowing him to deliver projects in weeks rather than months.


Real-World Applications: Success Stories

Ondrej has implemented several critical projects with Jmix, including:

1. Czech Academy of Sciences – Economic Department

2. Scientific Evaluation System

For smaller projects, Ondrej notes that a 15 – 20 screen application can be built in just two weeks — a testament to Jmix’s efficiency.


Recommendations for Using Jmix

Based on his experience, Ondrej recommends Jmix for:

– Freelancers and solo developers looking for an efficient and powerful development framework.
– Large organizations needing rapid prototyping to validate business concepts quickly.
– Internal business applications across industries, including banking, research, and corporate sectors.

Jmix’s flexibility and ease of development make it a strong choice for a wide range of projects with a predictable number of users.


The Future with Jmix

Ondrej plans to continue using Jmix for upcoming projects, particularly for internal company systems. His goal is to avoid the “front-end fatigue” of frameworks like React and Angular, focusing instead on solving business problems efficiently.

His Advice to Other Developers:

“If you want to concentrate on business logic and avoid hunting pixels or debugging race conditions, Jmix is the way to go. It’s a powerful tool for freelancers, prototyping, and large enterprises looking for manageable solutions.”

What if you need to embed features from a Jmix, Vaadin, or Spring application into another website or web application?What if you need to embed features from a Jmix, Vaadin, or Spring application into another website or web application? If your target platform isn’t a portal system, the common approach is to use IFrame technology for this purpose.

However, setting up IFrames today may not be entirely straightforward.

When deploying outside your local PC, the application opened in an IFrame will likely require browser cookie support to function properly. Modern security standards dictate that cross-site cookie exchange only works when the following requirements are met:

– Both the target site and the embedded application use a trusted HTTPS setup.
– Session cookies have the Secure property enabled.
– The SameSite property is disabled for these cookies.

This means extra server configuration is required, even for testing or staging environments.

As an example, we’ll use a server with the IP address 10.5.44.78, hosting both a Docker-based Jmix application and a static website that will be served with nginx frontend server configured for HTTPS. This could be run by a virtual server or a local virtual machine running a Linux-based OS.

For production, you can purchase SSL certificates or use free options like Let’s Encrypt/ACME software. For testing purposes, we’ll set up fake domain names and map them to the server’s IP in the /etc/hosts file (located in Windows\System32\drivers\etc on a Windows PC). Add the following line to this file:

“`10.5.44.78 app.jmix site.jmix “`

After that, when you open “`https://app.jmix in browser“`, it will send requests to IP-address we specified above.

For easier access, you can also install a public SSH key (which you may need to generate first) on the remote server using the following command:

“`ssh-copy-id [email protected]“`

## The website

For this simple website, we won’t use any libraries or frameworks. Instead, we’ll write code that opens a browser-native dialog window when a link is clicked, embedding the IFrame contents.

Place the following code inside a “`
