Install Syncler on your FireStick: This post will guide you through installing Syncler on your FireStick. Syncler works on all Fire OS devices, including FireStick 4K Max, FireStick 4K, FireStick 3rd Gen, FireStick Lite, Fire TV Cube, New FireStick 4K, and others.

What is Syncler?

Syncler is a streaming app designed to help you watch movies and TV shows. Currently, it is still in early development and does not support community addons, but this may change with future updates. Since Syncler is evolving, you might experience occasional bugs, but the app’s quality content makes it worth the occasional hiccup. Syncler doesn’t provide streaming links directly, so you’ll need a Link Provider Package. The free version supports Kosmos provider packages, and I’ll show you how to get one later in this guide.

The paid version, Syncler+, is an ad-free premium upgrade that includes several advanced features. It also supports Express provider packages, which offer higher-quality video streams compared to the free Kosmos option. Whether you use the free or paid version, I recommend pairing Syncler with Real Debrid for the best streaming experience. Note that Syncler isn’t available on the Amazon Store, so you’ll need to sideload it on your FireStick from the official Syncler website.

Syncler+ Subscription

Syncler+ is the premium version of the Syncler app. By subscribing, you unlock an ad-free experience and gain access to Express provider packages for higher-quality streams. Syncler offers four pricing tiers, starting at $1.50/month for 5 devices and going up to $5.00/month for 20 devices. You can purchase a plan directly from the official Syncler website.

Is Syncler Safe & Legal?

Syncler is officially available on the Google Play Store for mobile devices and Android TV, which suggests it’s a legitimate and safe app. For FireStick users, the app must be sideloaded via the official APK, which also appears to be safe—VirusTotal reports show no malicious flags in the APK file.

While Syncler itself is legal, it does not host content and requires provider packages to stream media. Some of these third-party packages may link to unverified or copyrighted content. As such, cannot guarantee the legality of all streams accessed through the app. To stay safe, stream only content that’s in the public domain or for which you hold the rights. For additional privacy and security, always use a VPN like ExpressVPN with Syncler.

Install Syncler on your FireStick and Android TV Box

Your FireStick or Fire TV is now set up and ready for streaming your favorite content. However, before you start, it’s important to note that everything you stream online can be seen by your ISP and government. This means watching free movies, TV shows, or sports might put you at legal risk. Fortunately, there’s a reliable way to keep your streaming activity private from your ISP and government — using a VPN on your Fire Stick. A VPN hides your real IP address and helps you bypass online surveillance, ISP throttling, and geo-restrictions.

I personally use and recommend ExpressVPN, which is fast, secure, and works seamlessly with all streaming apps on Fire TV and Fire Stick devices. We do not promote copyright infringement. But since it’s not always easy to distinguish between legitimate and illegitimate content sources, a VPN provides an extra layer of protection.

Here’s how to use ExpressVPN on your Fire Stick to keep your streaming activities private:

Step 1: Subscribe to ExpressVPN. It comes with a 30-day money-back guarantee, so you can try it risk-free for a month. If you’re not satisfied (which is rare), you can get a full refund.
Step 2: Turn on your Fire TV Stick and go to Find > Search.
Step 3: Type “ExpressVPN” (without quotes) into the search bar and select ExpressVPN from the results.
Step 4: Click Download to install the ExpressVPN app on your device.
Step 5: Open the app, enter your login details created during subscription, and click Sign In.
Step 6: Click the Power icon to connect to a VPN server. Your connection is now secure with one of the fastest VPNs available for FireStick.

How to Install Syncler Package (Free Syncler Setup)

Even when using Syncler with Real Debrid, you must install a provider package to access streaming links. Syncler supports two types: Kosmos (free) and Express (premium, for Syncler+ users). Express packages offer better quality and performance. Kosmos is available for free users but may cause buffering or occasional crashes due to lower-quality links. To get the best streaming experience, I highly recommend using Real Debrid with Syncler (instructions below).

Here’s how to install the free Kosmos package:

Open Syncler multiple times until the left menu bar appears. Click Settings.
Select Provider Packages from the right menu.
Click Kosmos.
A pop-up will show an authorization code.
On your PC or phone, visit syncler.net/install, enter the code, and click Next.
Enter the URL: https://raw.githubusercontent.com/WeeklyProblem/Bouncy/main/bouncy.min.js and click Next.
Go back to FireStick and click DONE on the prompt.
The package will now be added to Syncler.

How to Connect Real-Debrid to Syncler on FireStick

To integrate your Real-Debrid account with Syncler, follow these steps:

In Syncler, click Settings from the left menu, then select Accounts on the right.
Click Real-Debrid.
A pop-up will display an authorization code. Visit real-debrid.com/device on your PC or phone and enter this code to authorize.
After logging in and authorizing, you will see a confirmation message and a notification on Syncler confirming your Real-Debrid account is linked.

Conclusion

If you have a Real-Debrid account, installing Syncler on FireStick is a must. The high-quality streams significantly enhance your viewing experience. Syncler’s simple, user-friendly interface organizes TV series and episodes neatly, making it easy to find and watch the latest movies and shows. I highly recommend this app and look forward to its future updates.
