VybeCiv

VybeCiv is a free single-player civ-style 4X that runs in your browser, with no download and no account. Start on Earth with the classic loop: found cities, choose research, build units and deal with AI rivals. Reaching orbit doesn't end the game. Earth collapses into a single hex on a Solar System map, and planets and moons become your new land. Do it again and the Sun's system becomes one tile in the Galaxy. Your older maps keep producing under a governor while you play the new tier. Progress saves in your browser. Built with PixiJS. The code was mostly written with Claude Code from my design specs, Grok helped with design and balance, and the music is by Suno. This is the first public build, so feedback on the first 10 minutes is very welcome.
