Originally a CLI performance tool, Guider now powers production systems at scale, offering:

- 180+ commands including 83 new in this release.

- Android tracing integrations (perfetto, atrace, binder, dumpsys, etc.)

- Crash/panic/ANR visualization via flame graphs

- Real-time monitoring (ftrace, file access, D-Bus, Android props)

- Python tracing from 2.x through 3.13

- TCP/UDS command API for embedding & automation

- Improved output formatting, usability, and system resource control

It’s more than a profiler — Guider acts as a continuous performance analysis service with server-friendly APIs.
