A production-grade data grid built from the first line for Svelte 5 runes - not a React grid wrapped in a Svelte shim. Compose the headless engine yourself, or drop in the full <SvGrid /> render component and ship. The MIT core has zero feature gating: no license key, no watermark, no row-count cap.

Install

Scaffold a working Vite + Svelte 5 app with SvGrid wired up:

npm create @svgrid@latest

Or add it to an existing app:

npm install @svgrid/grid

Quick start

<script lang="ts">
  import { SvGrid, type ColumnDef } from '@svgrid/grid'

  const rows = [
    { firstName: 'Ada',   age: 36, status: 'active' },
    { firstName: 'Linus', age: 54, status: 'active' },
    { firstName: 'Grace', age: 85, status: 'inactive' },
  ]
  const columns: ColumnDef<{}, (typeof rows)[number]>[] = [
    { field: 'firstName', header: 'First name' },
    { field: 'age',       header: 'Age' },
    { field: 'status',    header: 'Status' },
  ]
</script>

<SvGrid data={rows} columns={columns} />

That is a real, accessible grid. Sorting, filtering, virtualization, cell selection, and inline editing all wire up the moment you turn on the matching prop.

Capabilities

• Virtualization - row + column windowing; 100k x 100 stays smooth, with a 1M-row demo.
• Filtering - Excel-style filter menu, inline filter row, set / value-list filter, locale-aware matching, between operators.
• Editing - 14 built-in editorTypes (text, number, date, datetime, time, select, rich-select with typeahead, textarea, color, checkbox, list, chips, rating, password) plus a cellEditor snippet slot for anything custom.
• Selection - cell-range click+drag and Shift+arrows, copy/paste as TSV, Excel-style fill handle, row selection.
• Hierarchy - row grouping with aggregation, tree data, master/detail, full-width detail rows.
• Layout - row + column pinning, sticky header + first column, header drag-to-reorder, autosize, column sizing API, zebra rows.
• Data operations - find in grid (Ctrl+F), undo / redo, transaction API, optimistic updates, server-side row model with sort / filter / group pushdown.
• Accessibility - WAI-ARIA grid roles, full keyboard navigation, RTL, high-contrast theme.
• Engineered for production - first-class TypeScript types, CSP / Trusted-Types safe rendering, SSR-friendly, themeable via --sg-* CSS tokens.
• Lean - ~7.5 KB gzipped headless core, ~42 KB gzipped full render component; Svelte stays a peer dependency.

Headless or render-ready

SvGrid ships two layers from one package, so you can choose how much control you want:

import {
  // Drop-in render component
  SvGrid,
  // Headless engine + row-model factories
  createSvGrid,
  createCoreRowModel,
  createFilteredRowModel,
  createSortedRowModel,
  createGroupedRowModel,
  createExpandedRowModel,
  createPaginatedRowModel,
  // Feature modules
  tableFeatures,
  rowSortingFeature,
  columnFilteringFeature,
  columnGroupingFeature,
  rowExpandingFeature,
  rowPaginationFeature,
  rowSelectionFeature,
  // Cell renderers
  renderSnippet,
  renderComponent,
  type ColumnDef,
  type SvGridApi,
} from '@svgrid/grid'

• Headless - drive createSvGrid and the row-model factories, render your own markup. getGrid*A11yProps helpers keep custom markup accessible.
• Render-ready - <SvGrid /> is a complete, accessible, themeable grid you configure with props.

Compatibility aliases are provided for the framework-neutral names: createGrid, createGridState, subscribeGrid.

AI-native

SvGrid publishes an MCP server and llms.txt / llms-full.txt, so Claude, Cursor, and Zed answer with accurate, version-pinned APIs and all 150+ demo sources as context - not hallucinated methods.

Enterprise

The MIT core is free for any use, including commercial. The optional @svgrid/enterprise pack adds Excel / PDF / CSV / TSV / HTML export, paginated print, pivot tables with a drag-and-drop Designer, and AI helpers. OSS projects receive an Enterprise key free. See Pricing.

Documentation

• Getting started - end-to-end walkthrough.
• 150+ live demos - copy-paste recipes for every feature.
• Why headless? - when to compose vs. drop in.
• Theming - re-skin via --sg-* tokens and dark mode.

Who's behind it
