Run git diff HEAD~1 or paste code directly. Works with any git diff or plain code snippet.
Pick OWASP Top 10 for web vulns, Secrets for credentials, Deps for library risk, or Full Audit for everything.

| Feature | AI Security Code Review | SonarQube / Semgrep |
|---|---|---|
| Price | ~$0.003/review (Anthropic API) | $150+/year (SQ Dev) or Semgrep free tier with limits |
| Understands intent & context | Yes — reasons about logic, not just patterns | Rule-based pattern matching only |
| Setup required | None — paste and go | CI pipeline config, rules, baseline setup |
| Catches logical auth bypass | Yes | Only if a rule exists for the pattern |
| OWASP Top 10 | All 10 categories, contextually | Varies by rule set and language |
| Secrets detection | Yes — understands context, fewer false positives | Limited (Semgrep Secrets is paid) |
| Exhaustive / systematic | AI may miss some edge cases | 100% of code paths covered by rules |
The OWASP Top 10 mode checks for: injection flaws (SQL, LDAP, OS command), broken authentication, sensitive data exposure, XML external entities (XXE), broken access control, security misconfiguration, XSS (cross-site scripting), insecure deserialization, known vulnerable components, and insufficient logging. The Secrets mode catches hardcoded API keys, passwords, tokens, private keys, and connection strings.
Nothing is stored by us. The diff goes directly from your browser to Anthropic's API using your own key — no backend, no server, no logging. Your code never touches our infrastructure. Anthropic's API does not use inputs for model training by default. For highly sensitive codebases, review Anthropic's data processing agreement before use.
Static analysis tools (SonarQube, Semgrep) use pattern matching — exhaustive but context-blind. This AI tool reasons about intent: it catches logical vulnerabilities, insecure defaults, and subtle auth bypass patterns that rules miss. Best practice: use both. Static analysis for systematic rule coverage, AI review for reasoning about what the code is actually trying to do.
Paste the git diff when possible. Diffs give the AI the crucial context of what changed (the highest-risk code), they're smaller, and they cost less to analyze. For a new file or code without a git history, paste the file contents directly — the tool handles both.
A typical diff (200–500 lines) costs about $0.001–$0.005 with Claude Haiku, or $0.005–$0.02 with Claude Sonnet. You pay Anthropic directly at pay-per-token rates; there's no subscription or markup. Compare to SonarQube Developer Edition ($150+/year) or Snyk Team ($57+/month/developer).
No — but it dramatically shortens one. Use this to get a first-pass list of potential issues before human reviewers look at the code. Security-critical systems should always have expert human review; AI is best at surfacing issues for humans to evaluate, not replacing their judgment.
