Please don’t log into your bank with Servo just yet! Now that we’ve released our first developer preview, we’ll be investing in formal security audits and improving our security practices using both existing libraries and Rust -- more information coming soon!
Note: Servo.app is not currently signed, so Mac users may have a popup saying "Servo can't be opened because it is from an unidentified developer." If the popup lacks a "proceed anyway" option, close it then right click Servo.app and click "Open." This time the popup will have an option to proceed opening the application.
