Gitleaks
Fast secrets scanner for detecting hardcoded credentials and sensitive information in git repositories. Gitleaks scans git history, staged changes, and working directory files against 150+ built-in detection rules for API keys, passwords, tokens, certificates, and other secrets from major providers (AWS, GitHub, Slack, Stripe, etc.). Used as a pre-commit hook, CI/CD scan, or repo audit tool. Written in Go for high performance.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local tool — secrets are never sent externally. Scans for secrets rather than storing them. Go binary with strong memory safety. MIT licensed.
⚡ Reliability
Best When
You want a fast, standalone secrets scanner for git repositories with no account required — especially for pre-commit hooks and CI pipeline integration.
Avoid When
You need centralized dashboard, enterprise policy enforcement, or real-time monitoring across hundreds of repositories.
Use Cases
- • Scan git repositories (including full history) for accidentally committed secrets like API keys, passwords, and certificates
- • Block commits containing secrets using Gitleaks as a pre-commit hook via Husky or Lefthook in development workflows
- • Run automated secrets detection in CI/CD pipelines using Gitleaks detect command with SARIF output for GitHub Code Scanning
- • Audit new repositories before making them public or sharing access to detect historical secret exposures
- • Scan agent-generated code for accidentally embedded credentials before deployment using Gitleaks as a pipeline gate
Not For
- • Runtime secrets management — Gitleaks scans for secrets in code, not runtime secret injection; use Vault or AWS Secrets Manager for secret management
- • Non-git code repositories — Gitleaks is git-native; use TruffleHog or detect-secrets for non-git scanning
- • Compliance reporting at enterprise scale — GitGuardian or GitHub Advanced Security offer enterprise dashboards and remediation workflows
Interface
Authentication
Local CLI tool — no authentication required for basic scanning. GitHub token needed for scanning private remote repositories.
Pricing
Gitleaks core is MIT open source. Gitleaks Enterprise is a commercial product for organizations needing centralized management.

Known Gotchas
- ⚠ Gitleaks scans git history by default — 'gitleaks detect' scans all commits; use '--no-git' for staging area only or 'protect' subcommand for staged files only
- ⚠ False positives are common — test data, example credentials, and placeholder values trigger rules; configure allow-list patterns in .gitleaks.toml to suppress false positives
- ⚠ Secret values are shown in findings output by default — use --redact flag in CI to prevent secret values from appearing in CI logs
- ⚠ Gitleaks custom rules use TOML configuration — complex regex patterns must be valid TOML TOML strings with proper escaping of backslashes
- ⚠ git history scanning can be slow for large repos (10K+ commits) — use --log-opts to limit the commit range scanned in CI: 'origin/main..HEAD'
- ⚠ Gitleaks reports findings but does not remove secrets — remediation requires git history rewriting (BFG, git-filter-repo) or rotation of exposed credentials
