Guardrail：面向 AI 生成代码的本地安全扫描工具

🛡️ Guardrail - Safer AI Code, Fewer Fixes

🚀 Getting Started

Guardrail helps you check AI-generated code for security issues, performance problems, and common mistakes. It works as a local scanner, so you can review code before it lands in your project.

Use this page to download and run the app on Windows: Visit the Guardrail download page

📥 Download and Run on Windows

Open the Guardrail page in your browser.
Download the Windows file from the repository page.
If Windows asks for permission, choose Keep or Run anyway if you trust the source.
Open the downloaded file.
Follow the setup window on screen.
When setup ends, launch Guardrail from the Start menu or desktop shortcut.

If the file opens in your browser instead of downloading, right-click the download link and choose Save link as.

🖥️ What Guardrail Checks

Guardrail looks for common issues in AI-made code, including:

Security mistakes that can expose data
Slow code paths that waste time
Unsafe patterns in generated code
Bad file handling
Weak input checks
Copy-paste style code that should be simplified
TypeScript issues that can cause breakage
Problems that a normal linter may miss

It uses a set of 22 rules and can fix many issues with AST-based auto-fix. That means it can edit the code structure safely instead of only pointing out problems.

⚙️ What You Need

Guardrail is built for Windows users who want a simple setup.

You should have:

Windows 10 or Windows 11
At least 200 MB of free disk space
A modern web browser for the download page
Permission to run apps on your PC
A code file or project folder to scan

For best results, close large apps while Guardrail runs if your PC is slow.

🧭 How to Use It

Open Guardrail.
Choose the file or folder you want to scan.
Start the scan.
Review the flagged issues.
Apply fixes where you want Guardrail to change the code.
Save the cleaned file or project.

If you are checking code created by ChatGPT, Copilot, or another AI tool, scan it before you use it in a live project.

🔍 What You Can Expect

Guardrail is made for people who want a simple safety check before code goes out the door.

It can help you:

Catch risky code early
Reduce cleanup work
Keep code easier to read
Spot patterns that slow down an app
Fix common issues with one pass
Review AI output with more confidence

🧱 File Types and Project Support

Guardrail works best with common code files and app projects, such as:

TypeScript files
JavaScript files
Web app source folders
Small utility scripts
AI-generated snippets
Code from chat tools and coding assistants

It is a good fit for people who want a clear scan before they copy code into a project.

🛠️ Troubleshooting

Download does not start

Reload the page
Try a different browser
Right-click the link and save it
Check your internet connection

Windows blocks the file

Open the file details
Choose Run anyway if you trust the source
Make sure the file finished downloading

App does not open

Restart your PC
Download the file again
Check that Windows did not move it to quarantine
Try running it as an administrator

Scan looks incomplete

Make sure the full file or folder is selected
Try again after closing the file in another app
Check that the project files are not read-only

📁 Typical Use Cases

Guardrail is useful when you:

Ask an AI tool to write code for you
Want to check code before sharing it
Need a fast review of risky patterns
Want to clean up generated code before commit
Prefer a tool that fixes issues instead of only listing them

🔐 Safety and Code Quality

Guardrail focuses on the kinds of problems that often show up in AI-made code. That includes unsafe input use, weak guards around data, and code that works but does not scale well.

It gives you a clear path to safer code without making the process hard to follow.
