GitHub's Gitmos wall: the story behind the open-source "Mission Control" that made a dev cry "look mum"
omojumiller · x · 2026-10-27
Omoju Miller recounts building Gitmos, GitHub's real-time open-source visualization wall: a globe with pull requests arcing between cities, a Trending Developers list, and live data streams. A developer finding his own name at #4 went viral as "look mum i'm at github hq." Started from the Cerebro installation at GitHub Satellite 2019, the project had no roadmap slot or assigned engineers — Miller wrote the RFP, hired the creative team, built the data pipeline, and installed it in SF and Redmond.
