Who we are and how this site works.
We're a streaming comparison guide. katmoviehd tracks availability across all major platforms — from Netflix to free services like Tubi — helping you find the best way to watch anything.
Our content is independently researched and regularly updated. We compare platforms based on pricing, content libraries, and user experience. No streaming service pays for favorable coverage.
We may earn affiliate commissions when you sign up for streaming services through our links. This costs you nothing extra and supports the site. Affiliate relationships never influence our editorial content or recommendations.
