Secure Your Workflow with the Local Code “Vulnerability” Scanner
Ship safer code with the Local Code “Vulnerability” Scanner, a specialized developer tool that identifies security anti-patterns before they reach your repository. By running a lightweight, pre-trained LLM directly in your browser, this tool scans for hardcoded API keys, SQL injection risks, and unsafe functions without ever sending your source code to an external server. It is the ultimate “privacy-first” utility for modern security-conscious developers.
How to Scan Code for Vulnerabilities
- 01. Paste Snippet: Drop your JavaScript, Python, or SQL code into the secure editor.
- 02. Local AI Scan: The browser-based engine analyzes the logic and syntax patterns.
- 03. Review Findings: Get an instant risk score and a list of detected security flags.
- 04. Remediate: Apply recommended security fixes before your final git commit.
Frequently Asked Questions
How does it detect vulnerabilities without a backend?
It utilizes Transformers.js to run a DistilBERT model locally, combined with high-performance regex heuristics to catch common exploits in real-time.
Is my proprietary code kept private?
Absolutely. All processing occurs in your browser’s local memory (RAM). No code is ever uploaded, logged, or visible to FreeAIToolz.
Which programming languages are supported?
The scanner is optimized for JavaScript, Python, SQL, and PHP, identifying common patterns like injection, weak crypto, and hardcoded secrets.
Will it catch 100% of all security bugs?
While powerful, this tool is designed for rapid pre-commit checks. It should be used as a primary defense layer alongside dedicated SAST/DAST tools.
Does it require a high-end computer to run?
No. It uses an optimized, lightweight AI model that runs efficiently on most modern laptops and desktops through the browser.
Can I use this tool for commercial projects?
Yes. The Local Code Scanner is free for both personal and commercial use, helping developers maintain high security standards everywhere.
