## What it is
Tai-e is an easy-to-learn, developer-friendly static analysis framework for Java and Android programs, offering pointer analysis, taint analysis, call graph construction, and dataflow analyses. It is actively developed by an academic group and widely used as a foundation for published program-analysis research.

## Use cases
- build a custom static analysis for Java bytecode
- run taint analysis to find security vulnerabilities in Java apps
- generate call graphs for Java programs
- analyze Android apps for security vulnerabilities
- learn pointer analysis through course assignments
- perform context-sensitive pointer analysis research
- analyze Java microservice or database-backed applications

## When to choose
- you need a modern, extensible Java/Android static analysis framework with strong pointer analysis
- you are doing academic research or coursework in program analysis
- you need taint analysis or vulnerability detection on JVM bytecode

## When to avoid
- you need static analysis for languages other than Java/Android
- you want a turnkey commercial-grade SAST product without writing analysis code
- you need dynamic analysis or runtime instrumentation instead of static analysis

## Facets
- artifact type: framework
- maturity: active
- function: security, parser, developer-tools, plugin-system, cli
- domain: programming-languages, security, developer-tools, android-tools
- platform: jvm, cli, cross-platform
- tags: static-analysis, pointer-analysis, taint-analysis, call-graph, dataflow-analysis, android-analysis, program-analysis, research, algorithms
