Active·★ 289·MIT·Updated 2026-10-22

squirrelscan is an open-source CLI tool designed for auditing websites across various aspects like SEO, performance, security, and accessibility. It helps coding agents by providing exact fixes for identified issues and integrates seamlessly with popular AI development environments.

squirrelscan sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Comprehensive audit rules (300+ rules, 22 categories) covering SEO, accessibility, performance, and security.. A representative use case is Automated website QA and auditing in CI/CD pipelines.. The listed license is MIT. GitHub stars are currently 289. Relevant tags include Website Audit, SEO Optimization.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
