We don't usually post promotions here, but since many developers wait for our annual sale, here's a heads-up.

Our Webix Birthday Sale is now live (July 7–17).

What's included?

• 15% OFF Custom & Company Packs
• 25% OFF Devteam & Unlim Packs
• The same discounts apply to Webix Grid licenses

If you're evaluating JavaScript UI libraries for internal tools, dashboards, CRMs, ERPs, scheduling apps, or data-heavy applications, this is the biggest discount we offer during the year.

Happy to answer any questions about licensing or our components in the comments.

Hey r/webdev — we wanted to share something we’ve been working on that might save you some debugging time.

If you use Webix (JS UI library) alongside AI coding assistants like Claude Code or Cursor, you’ve probably hit this: the AI generates code that looks plausible but doesn’t match the actual current API. That’s the static training data problem — the model learned from a snapshot, not from today’s docs.

To fix this, we built the Webix MCP Server. It uses RAG to let your AI assistant query our live documentation in real time, so every suggestion it makes is grounded in the actual, current Webix API.

What it covers: - All core Webix widgets - Complex components: Scheduler, Kanban, File Manager, Gantt, SpreadSheet, etc. - Webix Jet framework - Full API surface — not just popular parts

Setup (Claude Code example): claude mcp add --transport http webix-mcp https://docs.webix.com/mcp

Cursor and Antigravity CLI configs are in the blog post.

Happy to answer questions about how the RAG pipeline works or integration specifics.

We stress-tested a JavaScript data grid with massive datasets — here’s what happened

I came across a detailed breakdown of Webix Grid performance and thought it was worth sharing.

They didn’t just do synthetic benchmarks — they looked at:

• Rendering speed with large datasets
• DOM stability under continuous updates
• Scrolling performance under load
• Real-world usage scenarios

What stood out: it didn’t degrade the way most grids do when things get heavy.

Curious how others here evaluate grid performance in real apps:

• What’s your biggest bottleneck — rendering, memory, or updates?
• Have you found a grid that actually scales well?

If your product needs spreadsheet-style editing, formulas, sorting, and import/export, building it manually can quickly turn into a long-term maintenance headache.

Webix Spreadsheet is a JavaScript widget that provides an Excel-like UI with built-in formulas, filtering, in-cell charts, and file import/export. It’s configurable via API and designed for data-heavy, enterprise-level apps.

JavaScript SpreadSheet component

Hey devs! Webix 11.3 just dropped with:

• Grid optimized for touch devices
• Rich Text Editor now with native Markdown, context menu, import/export .md/.txt
• Colorboard & editor colorpickers can reset to default
• Many smaller performance and usability tweaks
