Every so often an open-source project lands that feels less like software and more like a magic trick. God’s Eye View is a browser-based “spy satellite simulator” — a photorealistic 3D globe covered in live data: aircraft transponders, ship beacons, orbital elements for satellites, earthquakes, public traffic cameras. Click an aircraft and the camera locks on, drawing a fading trail. Ride along in a cockpit view that holds the terrain all the way down. Ask it, out loud, to show you something. It hit #1 on GitHub Trending in August, and one look at the demo explains why.
The project grew out of the God’s Eye View video series (5M+ views on YouTube), and the interesting part isn’t the drama — it’s the plumbing. Everything on the globe comes from public, mostly open feeds: ADS-B flight data, AIS ship positions, seismic networks, broadcast orbital elements. What the project does is fuse them into one explorable picture, running locally in your browser, with source you can read. As the README puts it: half the magic is that it looks like a forbidden cockpit, and the other half is that every line of code is inspectable.
Getting started is unusually friendly for something this elaborate. It runs without any API keys — flights, satellites, earthquakes and cameras work out of the box — and can be installed with one click through Pinokio, or from a terminal with the standard npm ci && npm run dev. Optional keys (Cesium ion for photorealistic terrain, Google Maps for search) are upgrades, not prerequisites, added through an in-app panel. The README is refreshingly honest about what’s real versus estimated: traffic is simulated along real roads, and camera positions are coarse estimates.
For home lab types, there are two hooks. First, it’s a genuinely fun self-hosted showpiece — runs on your own hardware, no accounts, no telemetry middleman. Second, it’s a masterclass in layering open data sources, and each layer is a separate module: if you have an idea for your own feed (a local sensor, a fleet tracker, anything with coordinates), it’s designed to be extended rather than just admired.
Worth a look even if you never extend it. There’s something quietly reassuring about a project that takes the surveillance aesthetic everyone finds unsettling and builds it entirely from data anyone can download — the trick turned inside out, handed back to you with the source attached.
