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.
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.
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.
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.
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.
