What We Check

Comprehensive static analysis across security, quality, performance and style

Security Analysis

  • Hardcoded credentials & secrets
  • SQL injection patterns
  • XSS vulnerabilities
  • Insecure crypto (MD5, SHA1)
  • Command injection risks
  • Path traversal issues

Code Quality

  • Cyclomatic complexity
  • Dead code detection
  • Duplicate code patterns
  • Long functions/files
  • Deep nesting issues
  • Magic numbers

Performance

  • N+1 query patterns
  • Blocking operations
  • Memory leak risks
  • Inefficient loops
  • Unnecessary re-renders (React)
  • Bundle size hints

Best Practices

  • Language-specific idioms
  • Error handling patterns
  • Async/await best practices
  • SOLID principles hints
  • Deprecated API usage
  • Missing documentation

8-Layer Analysis Engine

Every review runs 8 analysis layers in parallel — language-specific reviewers, taint tracking, duplication detection, dependency CVE scanning and CWE/OWASP mapping. Same rule sets as SonarQube, Semgrep, Bandit, ESLint and GitHub Advanced Security.

#LayerWhat It CoversRules
L1Language ReviewersJava, Python, JavaScript, TypeScript, Go, React, Scala, Dart, R, Node.js Security—
L2General / UniversalPII/GDPR (SSN, credit cards, emails), hardcoded secrets, license headers, TODO/FIXME audit, common anti-patterns across all languages—
L3IaC & DevOpsDockerfile, Terraform, CloudFormation, Ansible — secrets in config, privilege escalation, open ports, latest tags—
L4Dependency / CVEChecks package.json, requirements.txt, pom.xml, go.mod for known vulnerable packages, outdated major versions and license compliance—
L5Taint TrackerTracks untrusted input (req.query, req.body, argv) flowing into sinks (DB queries, exec, eval, file ops) — catches injection at the data-flow level—
L6Complexity / ASTCyclomatic complexity, nesting depth, function length, class size — structural quality metrics computed from the abstract syntax tree—
L7Duplication DetectorToken-hash-based clone detection — finds copy-paste blocks across files, near-duplicate functions, repeated logic that should be extracted—
L8CWE / OWASP MapperEvery issue automatically tagged with its CWE ID (e.g. CWE-89 SQL Injection) and OWASP Top 10 2021 category (e.g. A03:2021 Injection)—
