Claude AI Built a UFO Data Visualizer with Government Data in Hours
A Reddit user built an interactive UFO sighting visualizer using Claude AI, based on data released by the U.S. Department of War. The project was completed in a few hours and is hosted on Cloudflare. It lets users explore sightings on a map over time, with detailed overlays.
Key Features
- Timeline scrubber: Navigate by year to see sightings across different periods.
- Interactive pins: Click to zoom in; then click a specific sighting to open a sidebar.
- Sidebar details: View the original PDF, video, or documentation for each sighting.
- Moon phase & weather overlays: Toggle to see conditions on the exact day of each sighting.
- NUFORC data: Also included but not yet activated (planned for later).
Technical Details
- Built with: Claude AI (the model assisted in coding the entire application).
- Hosted on: Cloudflare (no tracking beyond Cloudflare's default).
- Data source: Official U.S. Department of War release; all data is government-provided.
- Privacy: The author states no tracking is implemented other than Cloudflare's standard analytics. The site is free to use.
Who It's For
This is a practical demo for developers interested in using AI coding agents to rapidly prototype data visualization apps with public datasets, and for anyone curious about UFO sighting patterns.
