NEON Grids
Lightning-fast desktop app for structured data. Spreadsheets that don't break your formatting, don't phone home, and don't take 8 seconds to scroll.
Spreadsheets, but actually fast.
NEON Grids is what we built when we got tired of waiting for Google Sheets to load, tired of Excel's 2003 menus, and tired of web-based spreadsheet apps that treat "open a file" as a network round-trip.
It's a native desktop app - built on Tauri and Rust, with the spreadsheet engine running right inside the window. You click, it responds. You scroll 100k rows, it scrolls. No loading bar, no "Connecting...", no surprise sync conflict.
We use it ourselves for portfolio tracking, agent logs, game balance sheets, project budgets. It's the tool we wanted and didn't find, so we shipped it.

NEON Grids · v1.3.0 editor
What's in the box.
The features we have on the roadmap - the ones we need for our own work. More land every week.
Fast by default
Built on Tauri + Rust. Native-speed scrolling through 100k-row sheets. No cloud round-trip, no spinner.
xlsx, csv, json
Round-trip the formats you actually use. Formatting, formulas, and sheet structure carry over - they don't get flattened on save.
AI-assisted cleaning
Point it at a messy sheet. It infers column types, normalizes dates, dedupes rows, flags outliers. You approve, it applies.
Local-first
Your files stay on your machine. No upload, no cloud lock-in. Open, edit, save - same flow as a normal desktop app.
Comments + threads
Drop a comment on any cell. Pin it to a row. Thread replies. Same model you've used in Docs, but in a real spreadsheet.
Conditional formatting
Color scales, data bars, formula-driven rules. Apply once, edit anytime, visual debug when a rule misbehaves.
Multi-sheet tabs
Workbooks with as many tabs as you need. Cross-sheet formulas, named ranges, frozen panes - all there.
Keyboard-first
Every action has a shortcut. Arrow-key navigation, command palette, undo/redo stack. Feels like an editor, not a website.
Built with
Boring, reliable parts. AI handles the repetitive work so the humans can focus on the rest.

Why we built it.
Native, not web.
Tauri + Rust means the heavy lifting happens on your machine, in compiled code. No JS bundle fighting the browser, no spinner between edits.
Files stay local.
Your sheets are your sheets. We don't sync them anywhere, we don't scan them, we don't train on them. Open a file from disk. Save it back to disk.
Looks the part.
Dark mode by default, neon edges, tight typography. Same visual language as the rest of the studio. Because if you're going to stare at a spreadsheet for 6 hours, it should look good.
