No trial clock, no watermark, no signup. Commercial use included. The paid tiers start where you change the data and where you take it out — editing, server-side data, styled Excel and PDF export, charts.
Install and render
npm install @kanunilabs/datagrid-reactimport { DataGrid } from '@kanunilabs/datagrid-react';
import '@kanunilabs/datagrid-react/styles.css';
<DataGrid
gridId="sales"
dataSource={rows}
rowKey="id"
columns={columns}
style={{ height: 600 }}
/>No bundler configuration: the Web Worker is compiled into the package and started from a Blob URL. Prefer no framework? createGrid() does the same without React.

Questions people ask first
Is it really free?
The Community edition is, for both components: 50 of the 82 DataGrid features work with no licence key, no watermark and no expiry, and commercial use is included. Paid tiers add editing, server-side data, styled Excel and PDF export, charts and multi-level grouping.
Is it open source?
No. Community is free of charge but proprietary — the source is not distributed. If an OSI-approved licence is a requirement for you, this is the wrong library and it is better to know now.
Which frameworks are supported?
React 18+ and plain JavaScript with no framework at all. The JavaScript renderer has full feature parity, enforced in CI, and ships a UMD build so a script tag is a complete install. Angular and Vue are not supported today.
How fast is it, really?
At 1,000,000 rows by 9 columns, on the code path the worker runs, median of 3 runs: numeric sort 101 ms, text sort 90 ms cached (1.8 s on the first query, which builds a sort index), equality filter 18 ms, free-text search 65 ms cached (413 ms on the first query). The performance page publishes the method and the command so you can run it on your own machine.
Do I need to configure a Web Worker?
No. The worker is compiled into the package and started from a Blob URL, so there is no file to copy into public/, no bundler recipe and nothing to import. Vite, webpack, Next.js and Parcel all work as they are — and so does no bundler at all.
One licence covers both components?
Yes. A paid key unlocks the Enterprise features of DataGrid and PivotGrid together. There is no second purchase and no second key.
What happens when my subscription ends?
You keep the last version you paid for, and applications already shipped with it stay licensed and keep working. You stop receiving new versions and support. Nothing you have deployed starts showing a watermark.
Can I try it before buying?
Install the Community edition and build with it for as long as you like — it is not a trial. For the paid features, every one of them has a live, editable demo in the playground, and the enterprise guides show the configuration. There is no time-limited Enterprise trial key today.
