## What it is
PySonar2 is a Java library that performs interprocedural type inference and semantic indexing of Python codebases. The resulting index powers code browsers, code search engines, and IDE-like developer tools.

## Use cases
- build a code search engine for Python repositories
- index a large Python codebase for go-to-definition navigation
- infer types across a whole Python project for static analysis
- generate an HTML code browser for the Python standard library
- power code intelligence features in an IDE or developer tool

## When to choose
- you need highly accurate cross-function type inference and definition lookup for Python at scale
- you are building a code search or code browsing product and want a proven index backend
- you need analysis accuracy beyond what typical Python IDEs provide

## When to avoid
- you want a polished end-user tool rather than a library to embed
- your project is not Python
- you cannot run a JVM-based toolchain (Java 8+, Maven) alongside a local Python installation

## Facets
- artifact type: library
- maturity: active
- function: search-engine, parser, developer-tools
- domain: developer-tools, programming-languages, parsers
- platform: jvm, cli, cross-platform
- tags: static-analysis, type-inference, code-indexing, code-navigation, code-intelligence, search
