3Category FAQ
How are categories organized on CodeUtilo?
Categories group tools by intent, such as AI workflows, developer operations, privacy checks, converters, and SEO tasks.
Are category pages indexable by search engines?
Yes. Category pages are static, crawlable routes with canonical metadata and structured data.
Do tools in these categories upload data?
Core tool processing is browser-side. Category pages help discover tools but do not process user input themselves.
