What is the difference between SVAR UI open-source components and PRO editions?

SVAR UI ships each component in two tiers: an open-source edition you can use without a paid license, and a PRO edition that adds advanced features aimed at enterprise applications. The split is not uniform across the library — Gantt Chart, Calendar, and Kanban have PRO editions, while DataGrid and File Manager are listed as available components without a PRO label in the same way. If you only need core scheduling, planning, data management, or file browsing, the open-source tier is the place to start; if you need the advanced features that ship with PRO, you check the Licenses page for terms.

Which components have a PRO edition

Based on the component list on the site:

The site describes the library as "open-source components built for speed, scalability, and easy integration," and notes that "some components come with PRO editions that add advanced features for enterprise applications." So the open-source tier is the baseline for every component; PRO is an add-on layer on specific ones.

What the open-source tier gives you

The open-source components are positioned around speed, scalability, and integration:

• Framework-native builds for React, Svelte, and Vue, so components drop into Next.js, Nuxt, and SvelteKit without fighting the framework.
• Minimal boilerplate — you configure complete components rather than composing low-level primitives.
• TypeScript support with strong type definitions for autocomplete, early error detection, and safer refactoring.
• Core functionality per component, such as sorting, filtering, editing, and virtualization for DataGrid; task dependencies, drag-and-drop editing, and customizable timelines for Gantt; flexible views, calendar groups, and recurring events for Calendar; customizable task boards for Kanban; and multiple views, file preview, and standard file operations for File Manager.

What PRO adds

The site's description of PRO is deliberately high-level: PRO editions "add advanced features for enterprise applications." The component blurbs list capabilities like task dependencies, drag-and-drop editing, customizable timelines, calendar groups, recurring events, and customizable task boards, but the page does not map each of those features explicitly to the free or PRO tier. That means you should treat the feature lists as describing the component overall, and confirm the exact free-vs-PRO boundary on the Licenses page before committing.

How to decide

• Choose open-source if you are prototyping, building an internal tool, or your requirements match the core capabilities listed for the component and you do not need enterprise-oriented extras.
• Choose PRO if you are building a commercial or enterprise application and the advanced features described for that component are on your requirement list.
• Check Licenses first if licensing terms, redistribution, or commercial use matter to your project — the site routes licensing questions to its Licenses page, and pricing details are not specified in the material available here.

One practical note: because the free/PRO feature boundary is not fully itemized on the main page, the fastest way to avoid a surprise is to open the Licenses page and the individual component page for the component you care about before you build around it.
