Code Quality Analysis

Code Quality

Automated code quality analysis that tracks technical debt, detects code smells, measures complexity, and enforces your team's coding standards — all inside the pull request workflow.

Debt & Smells

Technical Debt Tracking & Code Smell Detection

Quantify and monitor technical debt over time. Get estimated remediation effort in hours per issue and trend lines that show whether debt is growing or shrinking across sprints. Identify anti-patterns, god classes, long methods, feature envy, and 200+ other code smells.

  • Estimated remediation effort in hours per issue
  • Sprint-over-sprint debt trend lines
  • 200+ code smell patterns detected
  • God classes, long methods, and feature envy flagged
Complexity & Duplication

Complexity Analysis & Duplication Detection

Measure cyclomatic and cognitive complexity per function, class, and file. Surface hot spots where high complexity correlates with bug density. Find exact and near-exact duplicated blocks across your entire repository to reduce maintenance costs.

  • Cyclomatic and cognitive complexity per function
  • Hot spot detection correlated with bug density
  • Exact and near-exact clone detection
  • Copy-paste code pinpointed across the entire repo
Coverage & Standards

Code Coverage & Coding Standards

Track line, branch, and function coverage from your existing test suites. Identify untested paths and block regressions automatically. Enforce your team's style guides and naming conventions using ESLint, Pylint, Checkstyle, or custom rules.

  • Line, branch, and function coverage tracking
  • Automatic coverage regression blocking
  • Import rules from ESLint, Pylint, Checkstyle
  • Custom rules in a single shared configuration

Quality Gates

Block Low-Quality Code at the Gate

Define pass/fail thresholds for coverage, complexity, duplication, and debt ratio. Quality gates run on every PR and block merges that would degrade your codebase.

  • Coverage Threshold
    Reject PRs that drop line or branch coverage below your team's minimum
  • New Code Policy
    Apply stricter rules to new code only — don't penalise existing legacy debt
  • Complexity Cap
    Automatically flag functions whose cyclomatic complexity exceeds your limit
  • Duplication Budget
    Keep cloned code below a configurable percentage of total lines

Frequently Asked Questions

Everything you need to know about TigerGate Code Quality

Linters catch style and syntax issues in isolation. TigerGate Code Quality performs semantic analysis to measure cyclomatic and cognitive complexity, quantify technical debt in estimated remediation hours, detect near-exact code clones across the entire repository, and track test coverage trends over time. It produces a maintainability grade per component so teams can prioritise where structural improvement will have the most impact.
TigerGate supports 45+ languages with first-class semantic analysis, including JavaScript, TypeScript, Python, Java, Go, Ruby, PHP, C#, Kotlin, Swift, Rust, and C++. A further 33+ languages receive standard rule coverage. Language-specific rule sets are tuned per ecosystem so you get meaningful results rather than generic pattern matching.
Quality gates define pass/fail thresholds for coverage, complexity, duplication percentage, and new issues. On every PR, TigerGate posts inline comments on affected lines, updates a status check, and blocks the merge if any threshold is breached. You can apply stricter gates to new code only, so existing legacy debt does not penalise teams making incremental improvements.
TigerGate integrates natively with GitHub (PR comments and status checks), GitLab (merge request decoration), Bitbucket (Code Insights), GitHub Actions, GitLab CI, and Jenkins. Adding the quality gate to a pipeline takes a single YAML step. A SARIF export is also available for any CI system that supports the standard.
Yes, intentionally. Certain quality rules — such as detecting hardcoded literals, overly permissive exception handling, and unsafe API usage — also surface security-relevant patterns. TigerGate links these findings to its SAST results so teams see a unified risk picture rather than duplicate alerts from separate tools.
Most repositories complete a full quality scan in under 5 minutes with zero configuration required. Connect your repository, and TigerGate auto-detects languages and applies the appropriate rule sets. Thresholds for quality gates can be customised, but sensible defaults are applied immediately so you get value from the first scan.
