KanuniLabs DataGrid & PivotGrid

Performant data visualization in the browser has long required choosing between rich functionality and the responsiveness users expect. KanuniLabs addresses this by delivering a data grid and pivot table component that processes a million rows without blocking the user interface, handling sorting, filtering, and aggregation through a Web Worker engine that keeps the main thread responsive.

The product targets React teams and vanilla JavaScript developers who need to display, analyze, and export large datasets. It shines where off-the-shelf grids typically falter: applications that must handle real-world data volumes without sacrificing interactivity. The founder's engineering philosophy surfaces clearly in the execution—the most difficult problem solved was not the performance itself but making that performance accessible through a straightforward installation process. Web Workers typically require framework-specific configuration across bundler environments. KanuniLabs compiles the worker directly into the package and launches it from a Blob URL, meaning developers install the library and immediately have a functioning grid without additional setup in Vite, Next.js, webpack, or plain HTML.

DataGrid provides virtualized rendering of rows and columns with built-in sorting, filtering, grouping, and export capabilities. PivotGrid layers drag-and-drop field manipulation and aggregation on the same engine, making it suitable for users who need to explore data interactively. Both components support 12 locales including Arabic with full right-to-left rendering and six themes across light and dark variants. Calculated fields incorporate a formula editor designed around content security policies, avoiding dangerous eval patterns while still offering live preview and editing.

The licensing model clarifies a straightforward split: 98 of 136 documented features work without a license key, covering the functionality most teams rely on—virtualization, filtering, grouping, and basic export. No watermarks, trial timers, or sign-ups gate access to this tier, even for commercial use. The paid edition adds inline editing, master-detail views, styled Excel and PDF export, calculated fields with advanced functionality, and drill-down navigation. A single key covers both components. The approach inverts the typical freemium structure: the free tier delivers a complete product rather than a time-limited taste, making it genuinely useful for smaller teams and side projects while clearly signaling where businesses requiring full feature coverage should invest.

Verification is built into the product philosophy. The site runs a live playground with a million-row dataset under user control, making performance claims reproducible rather than theoretical. This transparency, combined with the straightforward business model and the pragmatic focus on solving real installation headaches, distinguishes the offering.
