Free Security Scan

No tricks, no strings — just free. We know not everyone can afford paid scanning, and shipping secure code shouldn't depend on your budget. Our free scan combines open-source tools with Hyrex, our proprietary pattern engine built from thousands of AI-powered scans. Without the 100+ AI agents behind our full scan, it won't go as deep — but it will still catch real issues in your code.

Use this as long as you need. We hope your project takes off and you can try our full scan when the time is right. Even paid users are always welcome to come back here between scans to save on credits as needed. We're here for you — we wish you the best success!

No account. No cost. Results in seconds.

Typically completes in 10-30 seconds

Explain these tools to me ▼

Gitleaks — Scans for hardcoded secrets, API keys, tokens, and credentials that should never be in source code.

Trivy — Industry-standard vulnerability scanner that checks your dependencies against the National Vulnerability Database and GitHub Advisory DB. Finds known CVEs in your packages with exact fix versions. Also detects infrastructure misconfigurations in Dockerfiles, Kubernetes manifests, and Terraform files.

Bandit — Python-focused security linter that detects common vulnerabilities like shell injection, unsafe deserialization, and hardcoded passwords.

ESLint — JavaScript and TypeScript code quality analyzer that catches bugs, anti-patterns, and potential security issues.

Semgrep — Pattern-based static analysis with 2,000+ community rules covering security, correctness, and best practices across 30+ languages.

flake8 — Python code quality checker that catches style issues, unused imports, and common programming errors.

Hyrex — HostileReview Hyrex Pattern Engine. Our proprietary rule database built from patterns discovered across thousands of previous AI-powered scans. These rules don't exist in any open-source tool. This is the most powerful tool used in the free scan because it contains more rules than all the others combined.

Intelligent Synthesis — AI-powered analysis that groups raw tool findings by root cause, explains real-world impact, and provides actionable fix guidance. Turns noisy tool output into a clear security report.

Why upgrade to the full scan?

Every tool above uses pattern matching — they can only find what they already have a rule for. Our full scan is fundamentally different. 100+ adversarial AI agents read and reason about every line of your code in its entirety — not surface scanning, not regex matching. They trace data flows across files, think like attackers, and find business logic flaws, authentication bypasses, privilege escalation chains, race conditions, and cross-file attack paths that no pattern matcher can detect.

When issues are found, the full scan generates a complete fix workflow — every vulnerability mapped to its exact file and line number with step-by-step remediation you can hand directly to your AI coding assistant (Cursor, Copilot, Claude Code) or follow yourself. No context confusion, no guessing which file to edit. Paste the workflow and your AI knows exactly what to fix, where to fix it, and how to verify the fix is correct. Or download patched files as a ZIP and drop them into your project.

Our scans are 100% — every line, every file, every path. In head-to-head tests on the same codebase, our AI agents consistently find 5-10x more critical issues than all open-source tools combined, and scan far deeper than even most commercial security platforms. Try the full scan →

Your code is safe. Source code is processed in memory and not stored after the scan completes. Free scans use open-source tools running locally on our servers. Review results can be deleted from your dashboard at any time.
