Announcing CallFlow Tracer - Advanced Python Performance Analysis Library

[rajveer43]

Hi Python community!

I'm excited to share **CallFlow Tracer** - a comprehensive Python library for tracing, profiling, and visualizing function call flows with production-ready OpenTelemetry export.

## Key Features
- **Interactive Visualizations**: Beautiful HTML call graphs with zoom, pan, filtering
- **OpenTelemetry Export**: Production-ready OTel integration with exemplars & sampling
- **Code Quality Analysis**: Complexity metrics, maintainability index, technical debt
- **Predictive Analysis**: Performance prediction & capacity planning
- **Code Churn Analysis**: Git history analysis & hotspot identification
- **11 CLI Commands**: Complete terminal interface
- **Framework Integrations**: Flask, FastAPI, Django, SQLAlchemy, psycopg2

## Quick Start
`bash
pip install callflow-tracer
callflow-tracer trace script.py -o trace.html
`

## Links
- **GitHub**: https://github.com/rajveer43/callflow-tracer
- **PyPI**: https://pypi.org/project/callflow-tracer/
- **Documentation**: https://github.com/rajveer43/callflow-tracer
- **VS Code Extension**: https://marketplace.visualstudio.com/ite...low-tracer

Perfect for debugging performance bottlenecks, understanding code flow, and production observability. Feedback welcome!


Try it out and let's make it even better together! Feedback, issues, and contributions welcome!
