Rowie showing a 1 GB CSV file with 17 million rows. Each column shows its type, values are coloured by type, and the selected row's fields are listed in the inspector.

Reads CSV, TSV, JSON, NDJSON, Parquet, Excel, SQLite and MongoDB — local, or on your servers over SSH.

Made for reading data.

Column headers labelled Int64, Date, String, Double and Boolean above rows of coloured values.

Fast at any size.

Rowie reads only the rows on your screen, so a 17-million-row file feels like a short one.

Questions & answers

How large a file can Rowie open?

Files much larger than your Mac's memory. Rowie loads only the rows on screen, so a 1 GB CSV with 17 million rows shows its first rows in about 0.2 seconds.

Does Rowie change my files?

No. Rowie only reads. Sorting, filtering and hiding columns change what you see, never the file or database. There's no account, no analytics and no cloud.

Can I connect to MongoDB Atlas?

Yes. Use any connection string, including mongodb+srv://, with a username and password, TLS, or an SSH tunnel.

How does Rowie connect to my servers?

Through the ssh already on your Mac, so your keys, the SSH agent and the hosts in ~/.ssh/config all work. A new server's fingerprint is shown before it's trusted, and passwords stay in your Keychain.

Is Rowie a subscription?

No. You pay once and keep Rowie, with every update. The first 100 licences are $19; after that the price is $49.

Which version of macOS do I need?

macOS 14 Sonoma or later.
