The Svelte 5 native data grid. Headless-first. Render-ready.

A modern data grid built from the first line for Svelte 5 runes, not a React grid wrapped in a Svelte shim. A headless engine you can compose plus a full <SvGrid /> render component you can drop in. MIT core, MCP server for AI assistants, 150+ live demos.

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

npm create @svgrid@latest

Or add it to an existing app:

npm install @svgrid/grid

<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, working, accessible grid. Sorting, filtering, virtualization, cell selection, and inline editing all wire up the moment you turn on the matching prop.

• Row + column virtualization. 100k × 100 stays smooth; there's a 1M-row demo too.
• Filtering. Excel-style filter menu, inline filter row, locale-aware text matching, set / value-list filter, between operator on numbers and dates.
• 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 else.
• 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, column sizing API.
• Operations. Find in grid (Ctrl+F), undo / redo (Ctrl+Z), transaction API, optimistic updates, server-side row model with sort / filter / group pushdown.
• A11y. WAI-ARIA grid roles, full keyboard navigation, RTL, high-contrast theme.
• Bundle. ~7.5 KB gzipped headless core, ~42 KB gzipped full render component (Svelte stays a peer).

The MIT community core has zero feature gating, no license key, no watermark, no row-count cap.

OSS projects get the Enterprise pack free. See Pricing.

SvGrid ships an MCP (Model Context Protocol) server so Claude, Cursor, and Zed give accurate, version-pinned answers about every prop, method, and event in the library plus all 150+ demo sources as context.

    "svgrid": {

A published llms.txt / llms-full.txt is also available for retrieval-augmented setups.

SvGrid is built by jQWidgets, the team behind jqwidgets.com and htmlelements.com. We've been shipping UI components since 2011 to 5,000+ companies including Samsung, Boeing, NVIDIA, Microsoft, Nokia, and Intel. SvGrid is our Svelte 5 native effort.

SvGrid is open core: the MIT @svgrid/grid is free for any use, and the project is funded by Enterprise licenses, not donations.

• Need commercial or priority support? It is included with Enterprise. OSS projects under an OSI-approved license get an Enterprise OSS key for free.

This is a pnpm workspace monorepo:

packages/grid/            @svgrid/grid        - MIT data grid
packages/enterprise/      @svgrid/enterprise  - paid feature pack
packages/mcp/             @svgrid/mcp         - MCP server
packages/create-sv-grid/  @svgrid/create      - scaffolder
examples/                                     - 150+ live demos
website/                                      - svgrid.com source
docs/                                         - markdown docs

• Node.js ≥ 18
• pnpm (the workspace pins pnpm@10.33.2 via packageManager; corepack enable will pick it up)

pnpm install            # install workspace deps
pnpm dev                # run the demo gallery at http://localhost:5174
pnpm build              # build packages/grid/dist
pnpm build:example      # build the demo gallery
pnpm dev:site           # run the website at http://localhost:5180
pnpm build:site         # build the website (writes website/dist)
pnpm test:types         # type-check every package

pnpm dev proxies to pnpm --filter @svgrid/grid-example-gallery dev. Inside the example, the library is linked via the workspace ("@svgrid/grid": "workspace:*"), so edits in packages/grid/src/** are picked up by Vite HMR with no rebuild.

• Getting started - end-to-end walkthrough.
• Why headless? - what the headless core gives you and when to reach for it.
• Tailwind integration - re-theming via --sg-* tokens, dark-mode wiring.
• Help index - topic pages for columns, rows, cells, filtering, editing.
• Missing features - honest gap list.

website/ contains the public marketing + docs site (Vite + Svelte 5). Published to GitHub Pages via .github/workflows/deploy-website.yml on every push to main. See website/README.md for routes, base-path config, and the one-time Pages setup.

Honest list:

• Column spanning (colSpan on cell context). On the roadmap, large effort.
• Built-in row dragging across grids. Demos cover the in-grid case; cross-grid is not in the engine.
• Variable row height on the <SvGrid> render component. The headless virtualizer does it today.
• Engine-level formula language. There's a working in-grid formula engine in a demo, but it hasn't graduated into the package.
• Custom calendar systems (Hijri, Buddhist, fiscal year) for the date editor. Gregorian dates / times / datetimes are built in.
