Star Debug: open-source Starlink terminal manager for Android and iOS

What it is

Star Debug is an alternative client for Starlink user terminals, written in Dart/Flutter and published on Google Play and the App Store as well as on GitHub (80 stars, 23 forks, last commit on 11 August 2026 at the time of writing). It was created in 2023 as part of Narodnyi Starlink, a Ukrainian volunteer initiative that keeps terminals running in places where connectivity is a matter of safety, which explains its focus on diagnostics rather than polish. The repository documents a reproducible-build procedure so that the published binaries can be verified against the source, which is unusual for a mobile app.

What you can do with it

• Decode DebugData: paste or open the JSON that the official Starlink app and web panel export, and read it as structured telemetry: statuses, alerts, basic statistics, current configuration.
• Live telemetry from a terminal reachable on the local network or through Starlink's online data, with snapshots you can store in the app's database and share as DebugData-compatible JSON.
• Dish commands: reboot, stow and unstow, GPS on and off; router reboot and basic Wi-Fi setup where the Starlink router is used.
• Connectivity check from inside the app, and a "My Starlinks" list for people who look after several terminals.

Who it is for

Installers and support teams. On a roof, the official app tells you whether the sky is obstructed; Star Debug tells you the alert codes, the software version, the phased-array orientation data and the timing of outages, and lets you send a stow command before you unbolt the dish. For a Starlink installer or a reseller running a small fleet for customers, being able to ask "send me your DebugData" and read it on the phone shortens most support calls. The maintainers also list the other community tools worth knowing: the Prometheus exporters, the Rust and Python gRPC clients, and starlink-grpc-tools, which is the reference for the dish's gRPC interface.

How to use it

1. Install from the store (or build from source following the repository's instructions if you need to verify the binary).
2. On the customer's phone, open the Starlink app, go to Settings, Advanced, Debug Data, and copy the JSON; paste it into Star Debug to decode it offline.
3. On site, connect to the terminal's network and open the live view; take a snapshot before and after re-siting the dish to document the improvement.
4. Use Stow before removal and GPS toggles when diagnosing location-related alerts.

Limits

Star Debug talks to the terminal's local gRPC service on 192.168.100.1 and to the data the Starlink app exposes; it cannot change plans, manage billing or read the Enterprise telemetry API that fleet tools such as the DataMiner connector use. Since May 2026 Starlink no longer exposes GPS location over gRPC for most service plans, so location-related features depend on the plan. It is a community project without commercial support.
