What does ShellDef do?

ShellDef is an AI-powered security scanner that analyzes shell scripts to detect dangerous commands, security risks, and inefficiencies. You can paste code directly into the web interface or upload .sh files, and within seconds receive a detailed report highlighting potential problems. The tool supports multiple shell environments including bash, zsh, fish, and PowerShell, making it versatile for different development setups.

What sets ShellDef apart is its combination of instant analysis and educational feedback. The AI doesn't just identify issues—it provides specific explanations through smart tooltips and can automatically generate corrected, optimized versions of your scripts. The recent CLI integration allows developers to run scans directly from their terminal, enabling seamless integration into existing workflows and CI/CD pipelines without switching contexts.

ShellDef is particularly valuable for developers, DevOps engineers, and system administrators who regularly work with shell scripts. It helps prevent system disasters by catching risky commands before execution, saves time on manual code reviews, and serves as an educational tool for improving shell scripting skills. The free plan offers generous token limits, while paid plans cater to heavier usage with priority support.
