Free, legal, and working when Cataz is down or blocked. These platforms are fully licensed, no VPN required, no legal risk, available on every US device.

Tubi has the largest free streaming library in the US at 50,000+ titles — five times Cataz's catalog. It's completely free, ad-supported with very light interruptions, legally licensed, and works on every device (iOS, Android, Roku, Firestick, smart TVs) without a VPN. For most viewers who want Cataz's breadth without the legal gray area, Tubi is the single best substitute.
Difference from Cataz: Tubi has ads (short and infrequent). Latest theatrical releases arrive later than Cataz — usually 90 days post-cinema.
Pluto TV offers 250+ live channels organized like a traditional cable guide, plus on-demand movies and shows. It's owned by Paramount and completely free. Standout for US sports fans — it has dedicated sports channels unavailable anywhere else for free. No signup required to browse, though a free account unlocks more content.
Plex combines 50,000+ free licensed titles with live TV and a media server for your own files — all in one app. The free tier is genuinely excellent. Plex also lets you stream your personal movie and TV collection from anywhere via a free Plex account. Available on every platform including Apple TV and older smart TVs.
Kanopy is the only major free streaming platform with zero ads. It partners with US public libraries and universities — if you have a library card, you have Kanopy. 30,000+ films with a heavy focus on independent cinema, documentaries, foreign films, and classic Hollywood. The PBS Kids collection is also included free. Not for blockbuster fans, but unbeatable for quality film with zero interruption.
Tubi is the best all-around alternative — 50,000+ titles, completely free, available on every device, no VPN needed, and legally licensed. For live TV, Pluto TV. For zero ads, Kanopy (library card required).
Kanopy is completely ad-free and legal — free with a US public library card or university affiliation. For a broader catalog without Kanopy's art-house focus, Tubi's ad load is very light (1-2 ads per break, infrequently).
Legal platforms receive theatrical releases on a delay (typically 90 days post-cinema under licensing agreements). Cataz aggregates content earlier. If you specifically need day-one new releases, no legal free service currently matches that — however, Tubi regularly receives major titles quickly and has the widest new-release catalog among free legal platforms.
Use an alternative when: Cataz is experiencing a full outage (rare but it happens), you want guaranteed legal status, or you're on a device where Cataz doesn't work well (like Apple TV). Tubi and Pluto TV are instant backups — no setup, no account needed for basic access.
