Our verdict on SmartClient
SmartClient is a web application framework from Isomorphic Software for teams building data-intensive business interfaces in JavaScript. Its focus is the browser-side application: a large component library combines grids and editing, dynamic forms and validation, charts, navigation, and layout controls. DataSource-based binding and RPC/server-data integration connect those interfaces to application data and Java or other server technologies. It is aimed at internal business systems and customer-facing enterprise applications, rather than teams seeking a framework centered on a different layer of web development.
The main distinction is the breadth of its interface and data features in one framework. Declarative security and data access controls sit alongside the visual components, while built-in navigation and layout help structure applications. The listed deployment target is self-hosted, with browser applications using SPA rendering. JavaScript and Java are the primary languages, and the framework is available for web. Teams that need extensive data grids, forms, validation, charts, and server integration are likely to find its scope relevant; projects looking for an ORM or AI features will need other tools for those needs.
SmartClient uses a freemium, dual-license model. The LGPL Edition is open source and includes the core framework. Pro, Power, and Enterprise are commercial editions, described as adding additional, advanced, and highest-tier enterprise capabilities respectively. The editions page does not publish commercial prices, so buyers should contact Isomorphic Software for a quote. Documentation, community, and email are the listed support channels. The free edition offers a way to work with the core framework under LGPL, while organizations that need the commercial capabilities should assess the editions and licensing with the vendor. Choose SmartClient when data-rich client interfaces are central; consider alternatives if the project needs a broader framework focus or an included ORM.
