Show HN: PySpector – a hybrid Python SAST with a Rust core, looking4contributors

Hi HN, My name is Tommy, and i’m the maintainer of PySpector, an open source static analysis security testing (SAST) hybrid framework for Python (now with around 19k PyPI downloads), that combines a Rust analysis core with a Python CLI.

I originally built PySpector because I kept running into two problems with existing Python security scanners: - performance issues on larger codebases - lack of deeper analysis (like inter-procedural taint tracking)

PySpector’s approach is: - a Rust core for fast, parallel analysis (making PySpector 71% faster than Bandit and 16.6x faster than Semgrep) - Python for orchestration and extensibility - multi-layered detection using regex, AST analysis, and taint flow tracking - static rules for LLM/AI model vulnerabilities - TUI for triaging issues

The project is still in beta and actively evolving. I would love some feedbacks, and i appreciate (a lot) contributions around: - security rule design (especially AI Security ones) - taint analysis - improvements to the Rust core that enhance performances - developer experience and documentation

If you work on static analysis, security tooling, AppSec or Rust/Python scripting in general, I’d really appreciate your thoughts (and help, if you're feeling generous xD)
