Versions:
hookecho is an advanced NEXRAD weather radar viewer developed by d4vid87, published as an open-source application built from scratch in the Rust programming language using the wgpu graphics framework and the egui user interface toolkit. Described by its developer as an homage to supercell-wx, the software is designed for meteorological analysis and situational awareness, serving weather enthusiasts, storm chasers, and users who require detailed radar data inspection. Its core capabilities include deep per-site Level 2 and Level 3 radar analysis, allowing examination of individual radar station data alongside broader national situational awareness views. The application also integrates MRMS data, future radar projections, forecast environment overlays, and warning intelligence features, providing contextual information about severe weather threats. Specialized detection functionality includes tornado debris signature (TDS) identification and rotation detection, which assist in recognizing potentially dangerous storm characteristics. The software falls within the weather and meteorology application category, with an emphasis on radar visualization and severe weather monitoring. Cross-platform support is a defining characteristic, as hookecho runs on Windows, Linux, and Android operating systems, making it accessible across desktop and mobile environments. The current release is version 0.12.0-beta.2, one of two published versions, and the beta designation indicates that the software remains in active development prior to a stable release. As an open-source project, hookecho offers transparent access to its codebase while delivering a feature set that combines per-site radar interrogation with national-scale weather monitoring. The combination of Level 2 and Level 3 product support, MRMS integration, predictive radar views, and automated detection of hazardous storm features positions the application as a comprehensive tool for users seeking detailed radar analysis across multiple platforms.
