Developers

App API

Building a mobile or desktop app? Connect it to its Trakys project and the project page shows sessions, events and crash reports — self-hosted, no third-party trackers, no separate dashboards. Opens August 10, 2026.

Setting it up

In Trakys, open Projects → Apps → + Connect, pick the project, name the app and choose its platform. Trakys hands you the build-time keys right there.
Usage analytics: the app key + host drop into any Aptabase-compatible SDK (Flutter, Swift, Kotlin, React Native, Electron…). A Flutter build, for example:
```
flutter build apk \
  --dart-define=APTABASE_APP_KEY=A-EU-0000000000 \
  --dart-define=APTABASE_HOST=https://apps.example
```
Crash reporting: the DSN drops into any Sentry-compatible SDK — crashes arrive grouped by issue, with stack traces.

What you see in Trakys

Block	Contents
Totals	Users and sessions per app, with deltas against the previous window
Usage	Sessions, events and versions over the selected period
Crashes	Crash reports grouped by issue, newest first
Builds	Debug builds ingest into their own stream — a dev device never pollutes release numbers

The backends are self-hosted (Aptabase for usage, GlitchTip for crashes); the numbers are read inside Trakys, on the app's project page — that is the dashboard.
