What is opentaint? (1/30)
01 / 30
To provide a high-performance, cost-effective, open-source static analysis engine tailored for AI security agents as an alternative to proprietary solutions like Semgrep Pro and CodeQL.
๐ก Why Built
It was created to allow AI agents to perform formal dataflow analysis and application security scanning locally or self-hosted, reducing LLM token consumption by avoiding sending raw codebase context on every security scan.
๐ฏ Audience
Application security (AppSec) engineers, AI agent developers, software architects, and organizations seeking cost-efficient, AI-ready static taint analysis engines.
๐๏ธ Architecture
Modular static analysis engine written in Kotlin with TypeScript/Node.js tooling interfaces (indicated by tsconfig.json and package.json), designed to construct control-flow and data-flow graphs to trace untrusted input (sources) to dangerous operations (sinks).
๐ Difficulty
Intermediate to Advanced
MODULES:src/ - Core taint analysis, dataflow processing, and rule evaluation logictests/ - Test suites for verification of taint analysis rules and engine behavior
Is opentaint Production Ready? (2/30)
02 / 30
Grade C
opentaint
opentaint is an open-source taint analysis engine designed for static application security testing (SAST) and formal dataflow analysis, built specifically for integration with AI security agents.
โ
Avoid
opentaint requires careful evaluation of architecture and dependency health before deployment.
C
Eliminates high token usage costs associated with directly feeding large codebases to LLMs for security analysis while replacing expensive proprietary static analysis tools like Semgrep Pro and CodeQL with a customizable, self-hosted alternative.
Learning Curve
2 to 4 weeks to master custom taint rule configuration, AST dataflow analysis, and AI agent integration.
