RetroGate is a macOS proxy server that sits between your vintage computer and the modern internet. It handles TLS, transcodes HTML5 to HTML 3.2, converts modern image formats, and integrates with the Wayback Machine for time-travel browsing.

Features

• TLS Bridge — Fetches HTTPS sites and serves them as plain HTTP to your vintage browser
• HTML Transcoder — Converts HTML5/CSS3/JS pages to clean HTML 3.2 (three levels: minimal, moderate, aggressive)
• Image Transcoder — WebP/AVIF → JPEG/GIF, with Floyd-Steinberg dithering for 1-bit displays
• Wayback Machine Mode — Set a date and browse the web as it was, with temporal consistency for sub-resources
• Built-in Start Page — Search gateway (DuckDuckGo), curated retro links, Wayback status
• Dead Endpoint Redirection — home.netscape.com, www.geocities.com, etc. → Wayback archives
• 10 Vintage Presets — System 6 through Mac OS X, Windows 3.1 through Windows XP
• PAC File — Automatic proxy configuration at http://retrogate/proxy.pac
• Response Caching — Wayback content cached locally (archived pages never change)
• Color Depth Support — B&W, 16 colors, 256 colors, Thousands, Millions
