Roku app development
runs on its own stack.

A different language, a free store.

Whether you searched roku app development, roku tv app development, or roku development app, they all point to the same process. It means writing a channel in SceneGraph (UI) and BrightScript (logic), Roku’s own languages, then sideloading it onto a real Roku device to test before submitting it for certification. Unlike Apple and Google, Roku charges nothing to enroll as a developer, build, or publish to the Streaming Store. What it does charge you is time: BrightScript has almost no overlap with the languages behind a typical mobile or web app, and certification checks exact performance numbers, not just “does it work.”

How different is BrightScript, really?

Same function, same logic, two languages. Toggle between them to see why developers coming from JavaScript still have a real learning curve on Roku.

function greet(name as string) as void
    if name <> "" then
        print "Hello, "; name
    else
        print "Hello, stranger"
    end if
end function

Same if/else logic either way, but BrightScript closes every block with an explicit end if / end function instead of curly braces — closer to Visual Basic than to C-style syntax.

Roku vs Apple TV vs Fire TV.

If you’re choosing which TV platform to build for first, the languages and requirements diverge more than most people expect. Roku and Apple TV both lock you into a single vendor stack; Fire TV is the outlier that accepts React Native.

Sources: Apple Developer Program membership details and Amazon Fire TV getting-started docs. Apple TV’s $99/year is the same Apple Developer Program membership that covers iOS, so there’s no extra fee if you’re already publishing an iPhone app — just an Xcode project on top of it.

Roku’s storefront is free to enter.

Enrolling in the Roku Developer Program, building a channel, and publishing it to the Streaming Store cost nothing in platform fees. That puts Roku in a different bracket from Apple and Google, both of which charge to even list an app.

Sources: Roku developer overview, Apple Developer Program enrollment, and Google Play Console registration. Your real cost on Roku is developer time — or a development company’s rate — plus a physical Roku device for testing, since certification testing has no general-purpose simulator.

Certification checks exact numbers.

Roku’s Static Analysis tool and App Behavior Analysis Testing time your channel against fixed benchmarks before it’s allowed into the Streaming Store. These are the ones that catch the most first-time submissions.

Source: Roku Channel Store certification criteria. Ad-supported and subscription channels have extra requirements on top of these — an app-ads.txt path for ads, and Roku Pay integration for in-channel purchases.

What would your launch actually cost?

Pick what you’re shipping. The total is store fees only — not the cost of building each one.

When a Roku app development company is worth it.

BrightScript and SceneGraph are niche enough that most web and mobile teams have zero in-house experience with them. If you already have engineers but none of them know the stack, a Roku app development company or a freelance BrightScript developer is usually faster than training someone from scratch — the node-based UI model and the language itself don’t transfer from a typical résumé.

The calculus is similar to the build-or-hire decision teams face with a wear os app: it’s another platform-specific runtime bolted onto a product that mostly lives elsewhere, and the question is whether that one surface justifies a specialist or a generalist stretching into unfamiliar territory. For a straightforward video or media channel, Roku’s own sample apps and documentation are often enough for a small team to ship without outside help.

What a Roku channel doesn’t answer is what you build for the phone in someone’s pocket. That’s a separate architecture decision — covered in native vs web vs PWA — and it’s out of scope for this guide, which is about the TV side only.

Two platforms, two codebases.

Newly is an AI app builder for iOS and Android — you describe an app and it generates a real React Native and Expo codebase, the kind that ships to the App Store and Google Play. It does not build Roku channels, and it would be misleading to say otherwise: BrightScript and SceneGraph are a different toolchain running on a different OS, and no amount of React Native tooling bridges that gap.

Where Newly fits is the other half of the product: if your Roku channel needs a companion iOS or Android app — a remote control, an account settings screen, a second-screen experience — that mobile app is exactly what Newly builds, starting at $25/month. The Roku channel itself still needs BrightScript, built in-house or through a Roku app development company.
