Last winter, a friend called me right after setting up her brand-new LG TV — excited, until she realized the one streaming app her whole family used wasn't in the LG Content Store. If you've hit that same wall, you're in the right place. Knowing how to install third party apps on LG TV opens up a lot more of what the screen can do, and this guide covers both software and hardware routes so you can pick what fits your situation. If you're building out a full connected home, our smart home guides have plenty more ideas to explore.
LG Smart TVs run on webOS — LG's own operating system for smart televisions. It's fast and polished, but the built-in Content Store is curated, meaning LG approves every app before it appears. Some streaming services are region-restricted. Others simply haven't been certified for the platform yet. That gap is exactly why so many people look for alternative ways to get their apps running.
You have real options here. Some methods work entirely in software — unlocking developer settings on the TV itself. Others involve plugging in a small external device that brings its own full app store. Both approaches are worth understanding, so you can make an informed call rather than just trying random things and hoping one sticks.

Before anything else, you need to identify which platform your LG TV runs. The installation method differs completely depending on whether you have a newer or older model, so getting this right first saves a lot of wasted effort.
To check which you have, press the Home button on your remote. If you see a card-based launcher bar at the bottom, you're on webOS. If the interface looks more like a basic grid with minimal animation, you're probably on Netcast. Everything that follows depends on this distinction.
The LG Content Store is intentionally curated. LG reviews and approves every app before listing it, which is good for security but frustrating when your preferred app doesn't make the cut. Common reasons an app might be missing:
None of these reasons mean you're completely out of options — they just mean the front door isn't open, and you need to find another way in.
If you'd rather not buy any new hardware, the software route is your starting point. LG actually includes a Developer Mode in webOS — a legitimate, official feature built for app developers that you can also use to install third party apps on LG TV from outside the official store.
Developer mode lets you push app files in .ipk format directly to your TV over your local Wi-Fi network. Here's how the process works step by step:
The main drawback is that developer mode expires every 50 hours. You'll need to log back in periodically to keep it active, and any apps you've installed may stop loading if the mode lapses. For something you use daily, that's a real inconvenience. Still, it doesn't require rooting or modifying system files — you're working within a supported official feature.
Some webOS models support installing apps via a USB drive, though this varies by model and webOS version. Check your TV's documentation to confirm whether your specific model supports it before spending time on the attempt.
For Netcast TV owners, the honest answer is that software options are very limited. Netcast's architecture doesn't support the same developer tools or sideloading workflows that webOS does. If you have a Netcast TV and want meaningful app flexibility, the hardware methods covered next are genuinely your better path. Think of it the way you'd approach any signal or input problem — sometimes the right connector changes everything, like it does with setups in this guide on how to play Xbox One on a laptop screen with HDMI.
The most common reason people want to install third party apps on LG TV is access to streaming content the built-in store doesn't carry. A few categories of apps are especially popular among sideloaders:
| Method | Cost | Difficulty | App Availability | Permanence | Best For |
|---|---|---|---|---|---|
| Developer Mode (webOS) | Free | Medium | Limited (.ipk apps only) | Resets every 50 hours | Tech-savvy users with specific app needs |
| USB Sideloading | Free | Medium | Limited (model-dependent) | Semi-permanent | Certain webOS versions only |
| Amazon Fire TV Stick | $35–$55 | Easy | Very high (Android apps) | Permanent (own device) | Most users wanting full app access |
| Google Chromecast with Google TV | $30–$50 | Easy | High (Google Play Store) | Permanent (own device) | Google ecosystem users |
Sometimes the cleanest fix is plugging something into your TV's HDMI port. Streaming sticks and boxes run their own operating systems and app stores, completely independent of webOS. You switch to them using your TV's input selector, and you suddenly have access to an entirely separate app ecosystem — no developer mode, no timers, no .ipk files required.
One thing that matters a lot for streaming sticks is a solid network connection. A weak or intermittent Wi-Fi signal translates directly into buffering and dropped quality. If your TV is far from your router, it's worth looking at the best wireless ethernet bridge options to extend a reliable wired-quality signal to that part of your home.
The Amazon Fire TV Stick plugs into any HDMI port and runs Amazon's Fire OS — built on Android — giving you access to both the Amazon Appstore and the ability to sideload Android APK files directly. Setup takes about ten minutes from unboxing to browsing apps.
To sideload on a Fire Stick, enable "Apps from Unknown Sources" in the device settings, then use the built-in Downloader app to grab APK files from the web. The Fire TV Stick 4K Max is worth the small price premium if you watch 4K HDR content or use apps that benefit from faster processing. The Amazon Appstore alone covers most mainstream streaming needs without any sideloading at all.
The Google Chromecast with Google TV runs Google's Android TV-based platform and gives you full access to the Google Play Store — one of the largest app libraries available on any TV device. Sign in with your Google account, and you're browsing millions of apps within minutes of plugging it in.
It also supports sideloading APK files once you enable developer options in the device settings. For anyone already using Android phones, Gmail, and Google Drive daily, this device tends to feel more natural than the Fire Stick — the interface and app recommendations integrate with your existing Google account activity.
Only download .ipk or APK files from sources you can verify. Unofficial app files can carry malware — and your TV shares a network with every other device in your home, so a compromised TV is a security risk for all of them.
This applies whether you're using developer mode on webOS or sideloading APKs on a Fire Stick or Chromecast. A few practical rules:
Smart TVs don't come with large amounts of internal storage, and webOS in particular slows down noticeably when storage fills up. A few habits keep things tidy:
For those who are also building out a home theater PC setup alongside a smart TV, the best video cards for HTPC guide is a useful companion read — performance decisions there translate directly to streaming and media playback quality.
Once your apps are set up, a small amount of ongoing attention keeps everything working smoothly. These steps apply regardless of which method you used:
A factory reset clears everything — sideloaded apps, saved settings, account logins — and returns the TV to its out-of-box state. It's a last resort, useful if your TV is running very slowly, apps crash repeatedly without clear cause, or you're passing the TV on to someone else.
Before you reset, write down which apps you installed and where you sourced them. Reinstalling goes much faster when you're not starting from scratch. Also worth noting: if a streaming stick is your primary device, a TV factory reset doesn't touch it at all. The stick runs independently and will be completely unaffected.
Some apps only appear in certain countries' versions of the LG Content Store. There are a few strategies people use to get around that:
Keep in mind that using a VPN to access content outside your licensed region may violate the terms of service of some platforms. It's worth reading the fine print before going that route.
After looking at all the options, here's a plain-language way to frame your decision:
The hardware approach has a small upfront cost, but streaming sticks are inexpensive and they future-proof your setup in ways that developer mode can't match. They also travel well — plug one into any hotel TV and your full app library goes with you. For most people weighing the options honestly, a $40 streaming stick paired with a solid home network connection is simply the most durable and low-maintenance solution available.
Your LG TV's built-in store is just the starting point — the real flexibility comes from knowing which door to use when that store runs out of options.
