Why is a desktop app better for catching website issues?

CodeFrog is a desktop app so you can catch problems in development on localhost before a cloud solution scans your production site. This means you can identify and fix accessibility violations, security issues, broken meta tags, HTML validation errors, and SEO problems during development — before they ever reach your users.

Cloud-based scanners like Ahrefs, Semrush, and WAVE can only scan publicly accessible URLs, meaning issues are only discovered after deployment. With CodeFrog, you can:

• Test localhost: Scan your local development server (e.g., http://localhost:3000) before pushing to production.
• Catch issues early: Find and fix accessibility, security, and SEO problems while you're still writing code.
• No public URL required: Test staging environments, internal tools, and pre-launch sites that aren't publicly accessible.
