squirrelscan is a website quality assurance tool designed for coding agents. It audits your site for SEO, performance, security, accessibility, and agent experience issues, providing exact fixes that your coding agent—like Claude Code or Cursor—can apply directly. The tool is open source (MIT) and has no account needed for local CLI audits.
Manual website audits are slow, and coding agents often need precise, actionable feedback. squirrelscan automates checks across 260+ rules and 21 categories, generating a health score and grade, plus concrete fix suggestions. It saves developers time by integrating into existing workflows via CLI, MCP, or API, and offers CI-friendly exit codes to gate builds on quality thresholds.
It’s for developers, QA engineers, and teams using AI coding agents to maintain websites. It’s best if you want to automate website quality checks and feed fixes directly into your agent. It is not for non-technical users who need a manual website auditor without code integration—though the cloud reports are shareable with teams.
Use squirrelscan to audit a site before launch, set up nightly audits to catch regressions, or integrate into your CI pipeline to fail builds on low scores. Its multiple output formats (console, html, markdown, llm, json, xml, text) make it flexible for both humans and agents.
