They are ok, you get links of 720p 1080p, they work better if you have a debrid account to get even more links. Also try https://cloudstream-apk.com/!

It’s great to see you exploring options for your Fire Stick! CinemaHD, BeeTV, CyberFlix, and CloudStream are popular third-party streaming apps known for offering a wide range of movies and TV shows. While they can deliver content similar to top pirated streaming sites, there are a few things to consider.

On the Fire Stick Lite, these apps can work well with proper installation, though they often require sideloading and a bit of setup. The user experience can vary, especially when it comes to buffering and stream quality. https://cloudstream-apk.com/, in particular, stands out due to its clean interface and the fact that it doesn’t rely on torrents, which sets it apart from apps like BeeTV and CinemaHD. CloudStream sources content directly from websites, which means fewer issues with broken or missing links. It also offers the option for dubbed content, which can be a big plus.

I recently tried streamio on firestick, the app worked great in terms of ui and responsiveness but the services it connected to never worked. 5 was on it by default and each allowed me to browse movies and series but when i attempted to watch them it returned an error or buffered forever. I also tried with and without a vpn to see if that affected it. Personally the way that still works best for me is using a browser such as sideloading firefox and then visiting the websites using a vpn like you would on a laptop

Edit: while im here, sideload the newpipe apk. Amazing frontend for youtube

Best option I have found is cloudstream though you might have to search a bit for the repos.
