Current release: MacSurf 2.0.5 "HACKADAY" — text renders at the correct size everywhere, a large modern-CSS pass, a much more capable JavaScript engine, and ad/tracker blocking. Still running ES2023 JavaScript (macQJS) and TLS 1.3, on a 25-year-old Mac. One click, free, no account.
Runs on a Power Macintosh G3 / G4 under Mac OS 9.1–9.2.2. Expand the StuffIt archive with StuffIt Expander and double-click to launch.

MacSurf is a full-time, one-person project. If it brought your old Mac back to the web, supporting on Patreon (free membership available) helps keep it going. Monthly members on Ko-Fi get weekly beta releases. Also on GitHub Sponsors, Discord and Bluesky.
