Hi Product Hunt 👋 ◆ KanuniLabs started with a problem every frontend developer eventually hits: the grid is fine at 10,000 rows, sluggish at 100,000, and unusable past that. The usual answer is "paginate it" — which is a workaround, not a solution, and the people who actually need to see a million rows know it. So the work went into the engine rather than the API surface: • **Web Worker pipeline.** Sorting, filtering, grouping and aggregation run off the main thread, so typing in a filter box never blocks the UI. • **Zero configuration.** The worker is compiled into the package and started from a Blob URL — no bundler recipe, no file to copy, no `workerUrl` prop. `npm install` is the entire setup on Vite, webpack, Next.js and Parcel. • **Two components, one engine.** A DataGrid and a PivotGrid, and a single licence key covers both. The **Community tier is free on npm and production-ready** — virtual scrolling, filtering, grouping with summaries, pinning, keyboard navigation, CSV export, saved views, 6 themes, 12 locales with RTL. No key required, no watermark. **Enterprise** adds what teams ask for once the grid is load-bearing: inline editing with validation and undo/redo, range selection with a fill handle, multi-level grouping, master-detail, tree data, charts, and styled Excel/PDF export. Don't take the performance claim on faith — the playground runs a million rows in your own browser with no signup: 👉 kanunilabs.com/playground Happy to answer anything about the architecture, the trade-offs we made, or where it still falls short. Honest questions welcome.
