City Builder by Browser Games Now; modified 2026-10-18.
Upstream: https://github.com/graememcc/micropolisJS
Commit: f13a1624d111d235e804bd80f48ba7c9f66a8e0f
Code: GPL-3.0 with additional notices in LICENSE; font: SIL OFL; jQuery: MIT.
The Micropolis name has a separate license; this distribution uses City Builder.
Changes: branding, removed external font import and Twitter widget, local source
and license links, noindex on runtime documents. Simulation code is unchanged.

To rebuild the extracted source with Node 24 and npm:
git init -b main
git add .
git -c user.name=Builder -c user.email=builder@example.invalid commit -m source
npm ci --no-audit --no-fund
npm run build
Output: dist/. The upstream build stamps a Git main revision, so a rebuilt
archive has a different build ID. See prepare-city-builder.py for the exact
original commit and transformation. jQuery's unminified source is in vendor/.
