Vaadin Components

Checked 2026-10-14 against official sources. Core packages are Apache-2.0; advanced Pro components use Vaadin Commercial License and Service Terms. Verified the repository README and separate button/charts package licenses; there is no single root license covering all packages. Integrate through a Vaadin Java application, documented React wrappers, or individual @vaadin Web Component modules; use CSS properties and the documented styling APIs for themes. Editorial: useful for enterprise grids, forms and application layouts, especially Java-backed products. It is not a free license to every showcased chart or spreadsheet component. Live USD pricing shows Pro at 159 per developer/month; the page also exposes an EUR 149 alternative. Every contributing developer, including contractors, needs a commercial license for commercial features. Enterprise is per application/year with unlimited developers and a custom quote. No perpetual individual-feature licenses are advertised. Tax treatment and the Pro minimum commitment/payment cadence were not confirmed; verify checkout terms before buying. No purchase or trial started. Vendor accessibility claims were not independently audited. No production integration or independent accessibility audit performed.
