Story
Story behind Handsontable

What began as a side project quickly gained traction in the developer community, becoming one of the most popular data-grid libraries worldwide.

Notes from the lab
See all postsA vacuum never stays empty for long. We said good riddance to a CMS and built our own tools instead.
We rebuilt handsontable.com on Astro and Cloudflare with no CMS: what we skipped, what we built instead, and two internal tools that came out of it.
Handsontable's AI tools: a Docs MCP server, Claude Code skills, Ask AI, Theme Builder Assistant, and a demo playground
A public Docs MCP server, Claude Code skills, Ask AI in the docs, an AI tab in the Theme Builder and a coding assistant in the demo runner: who each is for.

Shadow DOM support for web components and Salesforce LWC
As of Handsontable 18.1.1 the core handles the shadow boundary itself — mouse, focus and clipboard events resolve through shadow roots, with no wrapper.
One million rows later: how Handsontable fixed its performance
A benchmark said we ran out of memory at 500,000 rows. Three weeks and 31 pull requests later, one million rows render with the lowest heap in the test.
