Balloon Navigator is a modern navigation PWA designed specifically for sport/competition hot-air balloon pilots. It emphasizes “no account required, no installation needed,” and runs in the browser on Windows, Mac, Linux, Android, iOS, and iPadOS. That said, installing it as a standalone app is recommended to prevent the browser from clearing local data. Its positioning is highly specialized: this is not a general-purpose mapping app, but a tool built around hot-air balloon competition use cases such as waypoints, wind layers, marker drops, and team collaboration.
In terms of functionality, it offers a world map, offline map downloads, custom PMTiles maps, waypoint/track management, GPX/KML/OziExplorer/GeoJSON import and export, and a range of drawing tools. For GPS, it supports built-in GPS, external NMEA serial GPS, Bluetooth GPS, and Balloon Live Sensor, although BLS is not available on iOS, iPadOS, or MacOS, and Garmin USB PVT is not supported yet. Windreader can record wind direction and speed by altitude, and draw wind lines and wind zones. Marker Drop Calculator estimates the best time to drop a marker based on speed, altitude, and elevation. The Pro version also includes Live Tracking, Windreader sync, track sync, global elevation data, and Extensions.
From a developer-tools perspective, the most notable feature is the Pro Extensions API. Extensions are installed as HTML files together with a manifest.json, run inside a sandboxed iframe, and use postMessage, the Channel Messaging Web API, and JSON-RPC 2.0 to call internal application capabilities. This makes it possible to build custom panels, map overlays, or flight calculators, and developers can use frontend frameworks such as React, Vue, and Svelte. The documentation is strong, covering installation, keyboard shortcuts, maps, GPS, data formats, account sync, live tracking, and the Extensions API in solid detail.
The pricing information only states that standard features and maps are free forever, while Pro uses a subscription model; the article does not disclose exact pricing. Its strengths include strong offline capabilities, no account requirement, cross-platform support, a complete set of professional competition features, and fairly open data-format support. Its downsides are that it depends on browser capabilities, custom map creation is somewhat technical, some features require network access or Pro, and Extensions are still experimental and come with data-permission risks.
It is best suited to hot-air balloon competition pilots, event teams, and ground crews, especially in scenarios that require offline navigation, wind-layer assessment, and marker-drop calculations. The article does not provide information about access from China, so network connectivity, payment methods, and subscription availability cannot be assessed. If access is limited, alternatives may include OziExplorer or general-purpose offline map tools that support GPX/KML/GeoJSON.
