About

Serious tools to watch the sky — without ever crying "spaceship".

Vigi-Sky is an independent project, built solo. The idea is simple: give anyone, with a phone or a PC, instrument-grade tools to observe, measure and verify what they see in the sky — and turn an eyewitness account into usable data.

The rule behind everything: never claim "UFO detected". Every tool talks about clues, probabilities and limits, written in black and white. Most unexplained lights have a mundane explanation — Venus, a Starlink satellite, a plane, a reflection. Our job is to help rule those out honestly, not to feed the mystery.

Who builds Vigi-Sky

The project is run by a developer passionate about astronomy, known online under the alias drakkB. Everything is designed and coded solo: the web tools, the desktop app, the analysis engines. The reusable building blocks are released open source at github.com/drakkB — so the method is verifiable, not a black box.

What Vigi-Sky is not

It is not a full live network. Hatch UDB (18,116 cases, 1900–2002, Larry Hatch) is an imported, frozen archive. Public Vigi-Sky observations are at 0 until a witness consents to publication. The project starts on 15 January 2026. Reusable code is on github.com/drakkB.

What's built

VigiSky Sentinel — a free desktop app that analyzes a sky observation on the GPU: motion detection, light curves, night watch with automatic satellite counter-check, and a physics-based detector for AI-generated video (photon noise, micro-tremor, frame cadence).
Sky and Witness — two mobile stations: one names the star or satellite you aim at, the other turns a sighting into a precise measurement (azimuth, elevation, position, time) that feeds multi-observer triangulation.
sky-proof — the video-authenticity engine, released open source (Rust, zero dependencies, no machine learning).

Why

Because between the general public with no tools at all and institutions that don't open theirs, something was missing: citizen instruments that are free, honest about their limits, and respectful of your privacy (the app transmits nothing without your consent). A book accompanies the approach: "I saw something in the sky — the witness's guide".
