Disk Space	6.5 MB + cache for Wayback responses
Network	Vintage Mac on same LAN (or SheepShaver at 10.0.2.2)
Patience	Moderate (the Wayback Machine is a non-profit)
Emotional attachment to beige plastic	Required

Build From Source

For developers who like to see what’s under the hood (spoiler: it’s SwiftNIO all the way down):

git clone https://github.com/Simplinity/retrogate.git
cd retrogate
swift build
swift run RetroGate

Or open in Xcode:

open Package.swift

Requires Swift 5.9+ (included with Xcode 15+). The project has 50 tests across 9 suites. Run them with swift test. They all pass. We’re very proud of this.

Download RetroGate-1.0.0.dmg, open it, drag to Applications
Launch RetroGate — note the proxy address (e.g., 192.168.0.130:8080)
On your vintage Mac, set HTTP proxy to that address
Browse. Marvel. Tell your Quadra it’s not obsolete after all.

Fun fact: This entire download page weighs less than a single modern cookie consent banner.

RetroGate itself is smaller than the average npm node_modules folder by approximately four orders of magnitude.
