A developer launched Klaxon, a live earthquake map that runs with no backend infrastructure. The project is hosted at klaxon.live and serves real-time seismic data directly in the browser, which is an unusual architectural choice for a mapping tool that needs to pull constantly updated data.

Most earthquake tracking tools rely on server-side APIs or databases to aggregate and serve data. Klaxon strips that out entirely, suggesting it fetches feeds straight from public seismic data sources in the client. That decision cuts infrastructure costs to zero but raises questions about data freshness and reliability.

For hobbyists and quick-look tools, this approach works well enough. The project's appeal is simplicity—no servers to maintain, no database to manage, just a webpage that shows earthquakes as they happen. It's a lightweight alternative to heavy platforms like USGS visualizers or commercial monitoring dashboards.
