What is MacSurf?

MacSurf is a web browser for Classic Mac OS 9 PowerPC. CSS3, ES5 JavaScript, and PNGs with alpha — running on a G3 iMac.

Why this exists:

The web outgrew Classic Mac OS twenty years ago. Modern HTTPS finished it off around 2016. Pull a G3 or G4 out of the closet today and it can barely reach a single live website.

MacSurf is an attempt to fix that on the machine itself — no screenshot proxy, no remote terminal trick. A native browser, built with the tools that were already on the platform: CodeWarrior, Carbon, QuickDraw, Open Transport. Real CSS3 layouts and real JavaScript, running inside the 64 MB memory floor of a 1999 iMac. Since late May 2026 it speaks TLS 1.2 directly to the modern web through macTLS, a BearSSL-based stack that ships inside the browser binary with 121 trust anchors from the Mozilla CA bundle. No proxy needed anymore.

As far as we can tell, this is the first serious NetSurf port to Classic Mac OS, and the first browser ever shipped on Mac OS 9 with native CSS Grid, CSS custom properties, and ES5 JavaScript.
