What is Roku?

The short answer

Roku is a streaming device (or built-in TV platform) that connects your TV to apps like Netflix, Hulu, YouTube, and hundreds of other streaming services.

How does it work?

Roku connects to your Wi-Fi and turns any TV with an HDMI port into a smart TV. Once set up, you get a simple home screen where you can browse and open streaming apps — Roku calls them “channels.” You use the included remote to navigate, search, and control playback.

You need:

  • A TV with an HDMI port (almost any TV from the last 15 years)
  • A Wi-Fi connection
  • A free Roku account
  • Subscriptions to the services you want (like Netflix or Disney+)

Roku itself is free to use. You only pay for the device and whatever streaming services you subscribe to.

What forms does Roku come in?

  • Streaming sticks — small dongles that plug into your TV’s HDMI port (most popular)
  • Streaming boxes — slightly more powerful set-top boxes for better performance
  • Roku TVs — televisions from brands like TCL and Hisense that have Roku built right in
  • Soundbars — speakers with Roku streaming built in

Roku vs other streaming devices

The main alternatives are Amazon Fire TV Stick, Apple TV, and Google Chromecast. Here’s how Roku stands out:

  • Roku doesn’t favor any one service — it shows all your apps equally, unlike Fire TV which pushes Amazon content
  • It’s usually the most affordable option, with sticks starting around $30
  • The interface is simple and clean, which makes it great for people who aren’t tech-savvy

Is Roku worth it?

Roku is a great choice if you want a simple, affordable way to stream on a TV that isn’t already a smart TV — or if your smart TV’s built-in apps feel slow and clunky. It’s especially popular with people who have cut the cord on cable and want one place to access all their streaming subscriptions.
