Everything you need, nothing you don't

Comma does one thing and does it exceptionally well: editing CSV files with care and precision.

Plain files, forever

Your CSVs stay as CSVs. No proprietary formats, no database lock-in. Your data is always yours.

File over app

Apps come and go, but your files should last. Comma works with your filesystem directly—no imports, no exports, no migrations.

100% local

Your data never leaves your machine. No cloud sync required. No account needed. Ever.

Lightning fast

Native performance that handles millions of rows without breaking a sweat.

Beautiful editing

A clean, focused interface that makes working with data a pleasure, not a chore.

Developer friendly

Keyboard shortcuts, vim bindings, and a command palette. Built for power users.

The local-first philosophy

We believe your data should belong to you, forever.

1

Offline by default

Comma works entirely offline. No internet connection required. Open it on a plane, a train, or a remote cabin in the woods. Your workflow is never interrupted.

2

No vendor lock-in

Your files are just files. Plain CSV text that any tool can read. If you ever stop using Comma, your data works exactly the same way it always did.

3

Privacy is non-negotiable

We never see your data. We can't see your data. There are no analytics tracking what you edit, no cloud sync harvesting your information. Your work stays private.

4

Built to last

Comma is a one-time purchase, not a subscription. We're building software that will work for decades, not software that holds your data hostage for monthly payments.
