Hybrid code analysis tool with AI-powered explanations

Qodacode

Enterprise Code Intelligence Scanner - Hybrid security analysis with AI-powered explanations.

What is Qodacode?

Qodacode is a hybrid code analysis tool that combines:

• Deterministic Detection Engine: 4000+ security rules with zero false positives
• AI Explanations: Learn why issues matter with multi-provider AI support
• Supply Chain Security: Typosquatting and dependency attack detection

Three interfaces, one engine: CLI, TUI (interactive terminal), and MCP Server (for AI coding assistants).

Quick Start

# Install
pip install qodacode

# Quick security scan
qodacode check

# Interactive terminal interface
qodacode

# Full security audit
qodacode audit

macOS (Homebrew Python)

If you get permission errors with pip:

# Use pipx instead
pipx install qodacode

# Or use pip with --user flag
pip install --user qodacode

Troubleshooting

"command not found" after install:

# Check where qodacode is installed
which qodacode

# If conflicts with old version in /opt/homebrew/bin/
rm /opt/homebrew/bin/qodacode
pipx install qodacode --force

Python version error: Qodacode requires Python 3.10+. Check your version:

python3 --version

Features

Security Analysis

• Secret Detection: API keys, passwords, tokens, credentials
• SAST: SQL injection, XSS, command injection, path traversal
• Syntax Validation: Catch errors before runtime
• Custom Rules: Project-specific patterns

Supply Chain Security

• Typosquatting Detection: Catches malicious package impersonators
• Known Malware Database: 30+ confirmed attack packages
• Homoglyph Detection: Unicode lookalike attacks
• Keyboard Proximity Analysis: Adjacent key typos

AI-Powered Learning

• Junior Mode: Get explanations for every issue found
• Multi-Provider: OpenAI, Anthropic, Google Gemini, Grok
• Batch Processing: Efficient API usage

False Positive Reduction

• Semantic Context Analysis: Auto-filters safe patterns like os.environ, decrypt(), test fixtures
• Inline Ignore: # qodacode-ignore: SEC-001 to suppress specific lines
• .qodacodeignore: Gitignore-style exclusion patterns
• Baseline Mode: For legacy projects - only show NEW issues

Interfaces

CLI Commands

qodacode check              # Quick scan (syntax + secrets)
qodacode check --baseline   # Only show NEW issues (not in baseline)
qodacode audit              # Full security audit
qodacode typosquat          # Check dependencies for attacks
qodacode baseline save      # Save current issues as baseline
qodacode baseline show      # View baseline info
qodacode doctor             # Verify installation

TUI (Interactive Terminal)

Launch with qodacode (no arguments):

/check      Quick scan
/audit      Full audit
/typosquat  Supply chain check
/ready      Production ready?
/mode       Toggle Junior/Senior mode
/api        Configure AI provider
/export     Save results
/help       Show commands

MCP Server (AI Integration)

11 tools for AI coding assistants:

Tool	Description
quick_check	Fast syntax + secrets scan
full_audit	Complete security analysis
analyze_file	Single file deep analysis
check_dependencies	Typosquatting detection
get_issues	Retrieve current issues
explain_issue	AI explanation for issue
fix_issue	Get fix suggestion
get_project_status	Overall project health
configure_mode	Set Junior/Senior mode
list_rules	Available detection rules
search_patterns	Search for code patterns

Production Verdict

Qodacode gives a clear answer: Can I deploy this code?

if critical_issues > 0:
    NOT READY - Fix N critical issues
else:
    READY FOR PRODUCTION (N warnings)

Philosophy: Only critical issues block deployment. High/Medium/Low are technical debt to track, not security blockers.

Detection Engine

Engine	Coverage
Core Engine	Syntax errors, custom patterns
Secret Detection	50+ secret patterns (API keys, tokens, passwords)
Deep SAST	4000+ security rules across languages
Supply Chain	Typosquatting, malware, homoglyphs

Architecture

Qodacode uses a hybrid architecture for performance and security:

┌─────────────────────────────────────────────────┐
│  Interfaces (Python)                            │
│  CLI, TUI, MCP Server, LSP                      │
├─────────────────────────────────────────────────┤
│  Orchestration Layer (Python)                   │
│  Multi-engine coordination, deduplication       │
├─────────────────────────────────────────────────┤
│  Core Algorithms (Rust - compiled)              │
│  Fingerprinting, similarity, pattern matching   │
├─────────────────────────────────────────────────┤
│  Detection Engines                              │
│  Semgrep, Gitleaks, Tree-sitter, OSV           │
└─────────────────────────────────────────────────┘

The Rust core module (qodacode_core) provides optimized algorithms:

• Fingerprinting: Stable issue IDs using BLAKE3
• Similarity: Levenshtein distance for typosquatting
• Homoglyphs: Unicode lookalike detection
• Pattern Matching: Aho-Corasick for safe pattern recognition

Falls back to pure Python when Rust extension is not available.

Configuration

Configuration is stored in .qodacode/config.json:

{
  "mode": "junior",
  "language": "en",
  "ai": {
    "api_key": "sk-...",
    "provider": "openai"
  }
}

AI Provider Detection

API keys are auto-detected by prefix:

Prefix	Provider
sk-ant-*	Anthropic (Claude)
sk-*	OpenAI (GPT)
xai-*	Grok (xAI)
AIza*	Google Gemini

Severity Levels

Level	Meaning	Action
Critical	Security vulnerability	Must fix before deploy
High	Significant issue	Should fix, doesn't block
Medium	Code quality concern	Review when possible
Low	Minor suggestion	Nice to have

Languages Supported

• Python
• JavaScript/TypeScript
• Go
• Java
• More coming...

Why Qodacode?

Feature	Qodacode	Traditional Linters
Hybrid Analysis	Deterministic + AI	Rules only
Supply Chain	Typosquatting detection	No
AI Explanations	Multi-provider	No
Interactive TUI	Modern terminal UI	No
MCP Integration	AI assistant ready	No

Requirements

• Python 3.10 or higher
• pip (Python package manager)

External Dependencies

Qodacode automatically manages external binaries:

• Gitleaks: Downloaded on first use to ~/.qodacode/bin/ (or uses system-installed version if available)
• Semgrep: Installed via pip as a Python dependency

Acknowledgments

Qodacode orchestrates best-in-class open source security tools:

• Semgrep - Lightweight static analysis for many languages (LGPL-2.1)
• Gitleaks - Secret detection and prevention (MIT)
• Tree-sitter - Incremental parsing system (MIT)
• OSV - Open Source Vulnerabilities database (Apache-2.0)

These projects are the detection engines. Qodacode adds orchestration, deduplication, AI explanations, and unified interfaces (CLI, TUI, MCP).
