Frequently asked questions

Is the free tier open source?

No. The free packages (@kanunilabs/pivotgrid-core, @kanunilabs/pivotgrid-react, @kanunilabs/pivotgrid) are free to use but proprietary — you may install and ship them in your apps, but the source is not published and may not be redistributed on its own. See the LICENSE in each package.

What's the difference between free and Enterprise?

Community (the free @kanunilabs/pivotgrid-react and @kanunilabs/pivotgrid packages) is a fully usable pivot table: pivoting, grouping, sorting, filtering, conditional formatting, theming, localization, saved views, broad import, and CSV/JSON/clipboard/print export. Enterprise adds advanced analytics and BI-grade output — calculated fields, the prefilter builder, drill-down to source records, live chart integration, and styled Excel/PDF export — delivered via a private registry with a signed license key.

How does licensing work?

Each license is a signed key (KLAB1….) verified offline in the browser (no network needed) using an embedded public key. Keys are bound to your domains and tier. Manage domains in your dashboard — changing them re-issues the key.

Which frameworks are supported?

React (18 & 19), and plain JavaScript with no framework at all.

@kanunilabs/pivotgrid-react is the React binding. @kanunilabs/pivotgrid is the same grid built straight into the DOM: one createPivotGrid(element, config) call, no component tree, and a UMD build so a <script> tag is a complete install. Both are real renderers over one engine (@kanunilabs/pivotgrid-core), and the JavaScript config mirrors the React props by name.

Angular and Vue are not supported, and no adapter is planned for now: development stays on React and plain JavaScript. The engine itself is framework-agnostic — no DOM, no framework imports — which is what makes the plain JavaScript renderer possible.

Which browsers are supported?

The current versions of Chrome, Edge, Firefox and Safari. Internet Explorer is not supported. Supported browsers lists the oldest version of each browser that has every feature the grid uses, and what is tested in a real browser.

Can I use it in a commercial / closed-source app?

Yes. Both the free and Enterprise tiers may be used in commercial applications, including closed-source products.

How is this different from a full component suite?

A focused, modern alternative: a single high-performance PivotGrid with a Web Worker engine, a smaller install, per-developer pricing, and a private-registry delivery model — without buying a whole suite.

How do I get support?

Free tier: community support on GitHub. Paid tiers: open a ticket from your dashboard — Team and Enterprise get prioritized replies.

How do I request a feature or report a bug?

Send it to [email protected] or the contact form — a short description and, for bugs, the steps to reproduce are enough. License holders can also open a support ticket. Feature requests directly shape the roadmap, so don't hold back.

What happens when my subscription ends?

Nothing you have shipped changes. A paid license key covers every version released up to the end of the period you paid for, with no time limit, so an application built with those versions keeps running without a watermark. What ends is access to new versions through the private registry, and support.

A version released after that date is not covered: upgrade to it without renewing and it shows the watermark. While a subscription is active each renewal moves the date forward, so copy the current key from your dashboard before you upgrade.

Do you offer refunds?

Billing is handled by Paddle (our Merchant of Record), and refund requests go through Paddle. The refund policy explains what a refund means for your license.
