HOW VAADIN MAKES YOUR TEAM FASTER

Top 10 reasons

1

Ready-made full-stack components

Build complete business UIs from components that load data straight from your backend services, with no glue code. Choose the modern Aura theme or Lumo, or style everything with plain CSS and switch themes at runtime. A matching Figma library keeps design and code in sync.

Feature-rich components for modern business applications

Vaadin components go beyond basic HTML elements and load data from your backend services automatically.


New in Vaadin 25: Slider, Badge, Switch, Breadcrumbs, Table and Master-Detail Layout.

Browse included components
Beautiful out of the box, customizable to your style

Start with the modern Aura theme or Lumo, then customize the overall design, or any single component, with plain CSS.

Accessible by design

Accessibility can be a legal requirement. Enterprise Edition includes an annual third-party accessibility review with a VPAT covering WCAG 2.1 AA, Section 508 and EN 301 549.

2

Go full-stack and stop waiting for others

One team builds each feature end to end, from database to UI, in Java. No REST layer to design, no hand-offs between frontend and backend teams, and smaller iterations that ship faster. Even browser features like geolocation, clipboard and fullscreen are a Java method call away.

Eliminate latencies with end-to-end feature ownership

Vaadin's full-stack platform empowers a single team to develop features from the database to a compelling user interface. This autonomy, free from the need to wait for others, eradicates typical coordination delays. As a result, smaller, faster iterations become standard, speeding up time to market and improving overall quality.

Software architecture reflects your organization's structure

Decoupling the user interface from the backend often reflects the organization structure: the frontend team is separate from the backend team. While the specialization can be beneficial, the significantly faster cycle times in full-stack teams often yield much better engineering productivity and quality.

Less tech stack maintenance

Vaadin manages up to 750 dependencies for you, testing that they work together and patching security issues as they appear. Vaadin 25 cuts transitive dependencies by about 30% and runs on a modern baseline: Java 21, Spring Boot 4 and Jakarta EE 11.

4

Built on modern industry standards

Vaadin builds on technologies your developers already know. Java runs the backend, standard web components and HTML/CSS render the UI, and React is there when you want it. Vaadin 25 integrates with Spring Boot 4 and Quarkus.

Secure by default

Vaadin has a 25-year security track record in banking, government and other regulated industries. Vaadin keeps UI logic on the server, and the communication layer between browser and server is secured automatically.

Automated communication layer security
All communications are secured by default: no need to remember to manage REST API security by hand.
UI logic stays on the server

Vaadin keeps UI logic on the server, out of reach of inspection and client-side attacks.

Secure defaults out of the box

Unsafe URLs are blocked, clickjacking protection is on, and newly published npm packages are held back to reduce supply-chain risk.

Spring Security built-in
Integrated with de-facto standard Spring Security authentication and access-control framework.
ISO 27001 certified

Vaadin's delivery and maintenance processes are certified to ISO 9001 and ISO 27001.

Enterprise Edition

An annual third-party security review, plus security fixes before public disclosure.
