We want to build an amazing spreadsheet.

We're starting with macOS because that's where we're most frustrated.

We used to spend 10+ hours a day in spreadsheets on Wall Street and loved Excel. Ever since we switched to macOS, we've missed that experience.

So we decided to build it ourselves.

We know the bar is extremely high, and we hope to exceed it. It might take a while, but we're committed.

We hope you'll join us on this journey.

Give Subset a try and let us know what you think.

Engineering

Built on strong technology foundations

We've been building Subset for more than 4 years, and we're obsessed with performance.

Rust-based spreadsheet engine

A fast and reliable foundation, suitable for large datasets, complex workbooks and maximum compatibility with existing spreadsheet formats.

Custom sync protocol

Version history, offline editing, and realtime sync, built on an algorithm faster and more memory-efficient than CRDTs and OTs.

Cross platform desktop app

Built on Tauri, a secure and lightweight application foundation that allows us to support Windows and Linux in the future.

Testimonials

Don't take our word for it

Here's some of the nice things people have to say about Subset.
