Hey r/programming,

**XLogger** – a web-based Android log viewer that runs entirely in your browser. No app to install, no server uploads. Everything (parsing, filtering, even AI analysis) happens locally.

**Why:**

- Tired of juggling adb logcat, grep, and text editors

- Wanted something that works on any device (desktop + mobile)

- Needed to keep logs private – no sending sensitive data to third parties

**What it does:**

- **Regex & keyword filtering** – multi-line keywords, exclusions, case-sensitive/whole-word

- **Time range** – filter by start/end time or “last N minutes”

- **Log level** – V/D/I/W/E with one click

- **PID/TID filter** – narrow down to specific processes/threads

- **Archive support** – drop .zip / .tgz / .tar.gz, it stream-extracts and finds log files

- **Rules** – save common TAGs/keywords and apply with one click

- **Context view** – click a filtered line to see its context in the original log

- **Optional AI analysis** – analyze filtered logs with AI (requires backend config)

**Privacy:**

- All parsing and filtering run in the browser

- Logs stored in IndexedDB (local only)

- No server upload unless you explicitly use AI analysis

Works on desktop and mobile. Feedback welcome.
