Before you begin
A few good
questions.
Marble is in early beta.
Here’s what to know.
What is Marble?
A browser on an infinite canvas, in early beta. It’s designed for research sessions alongside your everyday browser. The pages are live.
Where does my data go?
The canvas is a file on your Mac. No account. No sync. Your cookies, cache and logins stay in your local profile. Passwords stay in the system keychain.
Does it work offline?
The board lives on disk. Opening live web pages still needs an internet connection.
Are there ads?
None from Marble. Page ads are blocked by default; you can turn that off.
Do I need a Mac?
For now. Marble runs on Macs with M1 or newer, on macOS 14 or later. Join the Windows waitlist.
Is it free?
Yes. The board and features are free. A Research version for researchers and students is in the works.
