8 Free Movie Apps for Firestick That Are Legal to Install (2026)

Tubi, Pluto TV and Plex are the best free movie apps for Firestick: Tubi has the broadest on-demand library, Pluto TV mixes live channels with movies, and Plex adds your own media server. This guide is for US viewers who want licensed apps from the Fire TV Appstore, not sideloaded ones. The main caveat is that "free" means ads on most of these. Kanopy and Hoopla skip ads but only work if your library or school participates, so check that before you count on them.

8 Free Movie Apps for Firestick: Quick Comparison

1. Tubi

WHAT YOU ACTUALLY GET: free, ad-supported movies and shows for $0, with no account required to browse. Tubi is the closest thing to a general-purpose free movie library on Fire TV. Signing up is optional and only adds extras such as a saved list. There is no subscription tier to worry about, and you do not need a credit card at any point.

To install it, search for Tubi on your Fire TV home screen, select Get, then open the app and start browsing by genre. Check that the publisher listed is Tubi before you download. If you want a place to track what you have tried across several apps, the Firestick movie apps watchlist is a handy companion.

Watch out: ads play during movies, and titles rotate in and out, so something you saw last month may be gone. Verdict: start here if you only install one app. Last checked: November 3, 2026, via the Tubi site.

2. Pluto TV

WHAT YOU ACTUALLY GET: free live channels plus an on-demand movie library for $0, supported by ads. Pluto TV's Fire TV app works two ways. You can flip through scheduled channels like a cable guide, or open the on-demand section and pick a specific movie. Pluto describes its Fire TV offering as hundreds of shows and thousands of movies, so the library is large, though it is not the newest releases.

Installing is a single step: search for Pluto TV in the Fire TV Appstore and select it. Pluto's own support page lists the supported devices, and that is the page linked here. If you are comparing several free services beyond movies, 12 free streaming video services US viewers can use puts them side by side.

Watch out: live channels run on a schedule, so you may join a movie halfway through unless you use the on-demand shelf. Verdict: pick this when you want something on in the background without choosing. Last checked: November 3, 2026, via Pluto TV support.

3. Plex

WHAT YOU ACTUALLY GET: ad-supported free movies and shows at $0, plus the option to connect your own media server. Plex started as media-server software, and it now also carries a library of on-demand movies you can watch without hosting anything. The linked page describes Plex Pass, the optional paid tier. The Plex Pass price is not confirmed here, so check that page before paying for anything. You do not need it to watch the free catalog.

Install the Plex app from the Fire TV Appstore, open it, and follow the prompts. If you run a Plex server at home, sign in with the account that owns it to see your own library alongside the free titles. Watch for any account or sign-in prompts on first launch.

Watch out: the app mixes free content, your personal library and paid features, so the home screen can feel crowded at first. Verdict: best for anyone who already has movie files at home. Last checked: November 3, 2026, via Plex support.

4. The Roku Channel

WHAT YOU ACTUALLY GET: free, ad-supported movies and live TV at $0, but only titles marked free. Despite the name, The Roku Channel is not limited to Roku hardware, and it has a Fire TV app. It carries classic movies and originals with ads, and it also lists paid content, which is where people get tripped up.

Install by searching for The Roku Channel in the Fire TV Appstore, then browse and look for the free label before pressing play. If a title asks you to rent, buy or subscribe, back out and pick another. Use the official Roku Channel site as a catalog preview; install from the Fire TV Appstore.

Watch out: free and paid titles sit side by side, and the app may prompt you to sign in. Verdict: a good second app once Tubi and Pluto TV are set up. Last checked: November 3, 2026, via The Roku Channel.

5. Xumo Play

WHAT YOU ACTUALLY GET: free, ad-supported live channels and on-demand movies at $0. Xumo Play feels like a channel guide first and a movie library second. That suits people who like to turn something on and see what is playing, with on-demand titles available when you want to choose.

On your Fire TV Stick, search the Appstore for Xumo Play and confirm the listing is the official app before you download it. Once installed, open the guide for live channels or the on-demand section for movies.

Watch out: the same app name can appear in lookalike listings, so check the publisher, and expect ads at regular intervals. Verdict: worth adding if you enjoy a cable-style guide without a cable bill. Last checked: November 3, 2026, via the Xumo Play site. Confirm Fire TV availability by searching the Appstore.

6. FilmRise

WHAT YOU ACTUALLY GET: free, ad-supported movies and TV at $0, with Fire TV availability that depends on your region. FilmRise is a smaller catalog than Tubi, and it works well as a second place to look when a title you want is not on the bigger services. Browsing it is mostly about discovery rather than finding one specific film.

To use it on Fire TV, search the Appstore for FilmRise and check that the listing is available in your region. If the app does not appear, the FilmRise website is the fallback, and you can still look through what it offers before deciding whether to chase it down. No account is shown as a requirement in the research, but confirm on first launch. If you also want anime, see 10 best anime streaming sites for US viewers.

Watch out: availability varies, so you may not find a Fire TV app on every device or in every region. Verdict: a useful extra, not a first install. Last checked: November 3, 2026, via the FilmRise site.

7. Kanopy

WHAT YOU ACTUALLY GET: ad-free films at $0 through a participating public library or university, with viewing limits set by that institution. Kanopy is a library service, so it has no public sign-up. You need an eligible library or campus account, and the number of plays you get each month depends on your institution. It tends to suit indie, classic and documentary viewing better than new blockbusters.

First check the Kanopy site to see whether your library or school is listed. Then search the Fire TV Appstore for Kanopy, install it, and sign in with your library or campus details. If you are a student, 10 freebies college students can claim covers other perks worth checking.

Watch out: the Fire TV app may not be available to everyone, and limits vary by library. Verdict: the best ad-free route if your library participates. Last checked: November 3, 2026, via the Kanopy site.

8. Hoopla

WHAT YOU ACTUALLY GET: movies borrowed at $0 with a library card from a participating library, with monthly borrowing limits that may apply. Hoopla works like a digital shelf: you borrow a title, watch it for a set period, and it returns itself. The limit depends on your library, so confirm it with them rather than assuming a number.

Look up your library on the Hoopla site first. If it participates, search the Fire TV Appstore for Hoopla, install it, and sign in with your library card details. Borrow a movie from the app, then play it from your borrowed list. Our free streaming video services checklist can help you compare this against ad-supported options.

Watch out: if your library does not offer Hoopla, the app is of no use to you, and borrowed titles expire. Verdict: strong for ad-free viewing when your card works. Last checked: November 3, 2026, via the Hoopla site.

Already Have Prime Video? Check This First

Prime Video is already on most Fire TV Sticks and has movies labeled Free with Ads. It is a feature inside an app you probably own, not a separate install, so it is not counted in the list above. Crackle is also gone: its parent company went through bankruptcy and liquidation, the apps were delisted, and the site went offline in 2025. Tubi is the closest free replacement. Skip apps that ask you to sideload or promise every new release for free.

Verdict: Start here

• Best overall: Tubi, because it has the broadest free on-demand movie selection and does not require an account.
• Best for a specific reader: Kanopy or Hoopla if your library or school participates, since both are ad-free through your card or campus login.
• Skip if: you want new theatrical releases the week they come out. Free ad-supported apps rarely carry them.
• Try first: search the Fire TV Appstore for Tubi, install it, and check the publisher name before opening it. Then add Pluto TV for live channels.
