ChemTracker
See which planes are spraying above you — in real-time
What it does
ChemTracker predicts which aircraft overhead are leaving visible trails — in real-time. Using live ADS-B flight data, atmospheric conditions from 8 pressure levels, and the Schmidt-Appleman criterion, we analyze every aircraft within 250km of your location. Features: → Real-time flight map with contrail scoring → Sky Scanner: point at a trail, identify the aircraft → Golden hour alerts when visibility peaks → Evidence packs & field reports Free 14-day trial. No credit card. Worldwide.

Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…

I've created a web app for querying and visualization of ADS-B datasets: https://adsb.exposed/ Source code: https://github.com/ClickHouse/adsb.exposed/ The results significantly exceeded my expectations because the pictures are insanely beautiful, and the data is a treasure trove. It proves many statements that were not certain: - it is feasible to generate tiles by aggregation on a pixel level (instead of hexagons or rectangular grid); - it does not require JPG/PNG tiles - we can transfer raw bitmap data with zstd compression; - it is possible to…
- SASkies-adsb 2.0 – my 3D plane-tracking web app2025 · github.com · ▲59
Hello, I'd like to share a 3D plane tracking web app that I developed called: skies-adsb. Living near KMIA (a very busy airport), I spend a lot of time plane spotting and thought it would be cool to track planes in 3D. In October 2021, I built a prototype 3D ADS-B flight tracker called skies-adsb using p5.js. In April 2022, I released version 1.0 of skies-adsb, rewritten in Three.js. However, this release still relied on manual editing of GeoJSON layers. By late 2024, I had learned enough about GIS and GeoPandas to automate map creation using custom GeoJSON layers. During the Christmas…
