Corsair Gallian 100 SD Review: A Bold Keyboard With a Built-In Stream Deck

Introduction

Corsair has had a complicated history in the keyboard space. While the company was once a familiar name for many first-time mechanical keyboard buyers, its recent releases have struggled to keep pace with a rapidly evolving custom keyboard market. The Gallian 100 SD, priced at $350, aims to change that narrative by integrating a full Stream Deck directly into the keyboard. After spending time with it, the result is a fascinating mix of genuine innovation and frustrating compromises.

Who This Keyboard Is For

The Gallian 100 SD is clearly aimed at streamers, content creators, and power users who want macro controls without needing a separate device. The built-in Stream Deck panel replaces the need for an external Elgato Stream Deck, which can cost $149 for a basic model or $199 for the Stream Deck Plus. For someone already in the market for a Stream Deck, the Gallian 100 SD bundles that functionality into a keyboard, making the $350 price tag more defensible.

It is also worth noting that the keyboard is not wireless. The bottom case is plastic, and the top case is aluminum, though the aluminum feels less premium than expected. If you are looking for a wireless keyboard or one with a fully metal construction, this may not be the right choice.

The Built-In Stream Deck

The standout feature of the Gallian 100 SD is the Stream Deck panel built into the right side of the keyboard. It features a row of individual LCD screens that can be reprogrammed easily, along with three rotary knobs. The default setup is thoughtful, offering basic media controls and a toggle that switches the panel into a number pad mode, effectively turning the keyboard into a compact number pad keyboard.

The buttons feel mushy but are fine to press, and each one is its own screen, which makes customization straightforward. Without installing any Elgato software, the default integration works well. You can switch between different scenes and profiles without needing anything running in the background. This out-of-the-box experience is genuinely impressive.

Once you install the Elgato software, the experience becomes more powerful but also more clunky. You need to create an Elgato account, sync everything, and download multiple apps for native integration. The screen itself is the most useful screen ever seen on a keyboard, displaying real-time information that syncs with specific games, apps like Spotify, and even weather. There are presets available for games like Helldivers, Cyberpunk 2077, and World of Warcraft, though some of these presets cost extra, with some priced upwards of $13.

The amount of freedom offered by the Stream Deck software is not infinite, and it is not particularly coder-friendly, but it is still quite powerful. Being able to place a variety of apps and macros on the panel is genuinely useful. The integration with the built-in screen is the biggest perk, and no standalone Elgato Stream Deck offers a screen this large.

Keycaps and Switches

While the Stream Deck integration is a highlight, the keycaps and switches are a letdown. The keycaps are cheap shine-through keycaps, which is surprising given that Drop, the company Corsair acquired, made some of the best shine-through gamer keycaps available. The switches are linear switches from Corsair that sound chattery and rattly, which feels unacceptable at this price point in 2026. Even budget keyboards at $36 can offer smoother, creamier switches.

To their credit, the keyboard is filled with foam, which helps the typing sound feel relatively decent. It is not an abomination like some of Corsair’s previous keyboards, but it does not live up to the standards set by the custom keyboard community. The switches do feature a dual-stage spring, which is a nice touch, but the overall switch quality still falls short.

The keycaps and switches are swappable, so you can replace them if you are willing to invest more money on top of the $350 purchase. However, having to spend additional money to fix components that should have been better from the start is frustrating.

Build Quality and Design

The Gallian 100 SD has a split personality when it comes to build quality. The top case is made of CNC aluminum, but it feels cheap and not particularly cool to the touch. The bottom case is unapologetically plastic, and the keyboard is not wireless. For a $350 keyboard, this is a significant disappointment, especially when full aluminum keyboards can be found for around $100.

The unboxing experience is bare bones, though you do get a wrist rest and some basic cables. The wrist rest is fine, but it does not compensate for the overall lack of premium feel. The keyboard is also surprisingly light, which further reinforces the impression that corners were cut on materials.

Software and Customization

Corsair has opted for a web-based software separate from its older Corsair iCUE application. The web software is easy to use and provides basic controls for reprogramming keys and adjusting lighting. However, having it in a separate software is a bit annoying, especially if you already use other Corsair products.

The Stream Deck software, on the other hand, is where the real customization power lies. While the setup process is clunky, the end result is a highly customizable macro panel that can be tailored to your workflow. The default profile that appears after syncing is decent, and there are various presets available for different games and apps.

Buying Advice

The Corsair Gallian 100 SD is a unique product that offers an experience no other keyboard currently provides. The built-in Stream Deck is genuinely innovative, and the integration with the large screen is something that standalone Stream Decks cannot match. For streamers and creators who would otherwise buy a separate Stream Deck, this keyboard bundles that functionality into a single device.

However, the $350 price tag is steep, and the compromises in build quality, keycaps, and switches are hard to ignore. If you are willing to overlook these issues or plan to mod the keyboard with better keycaps and switches, the Gallian 100 SD has a lot of potential. But for most people, the right solution might still be to buy a separate Stream Deck and a better keyboard for the same budget.

Conclusion

The Corsair Gallian 100 SD is the most creative keyboard design in a long time. It combines a full Stream Deck with a mechanical keyboard in a way that feels genuinely useful. The screen integration is superb, and the default setup works well without additional software. But the cheap keycaps, rattly switches, and underwhelming build quality hold it back from being a truly great product.

If Corsair had paired the Stream Deck integration with better components, this could have been a standout keyboard. As it stands, the Gallian 100 SD is a promising framework that is ultimately undermined by cost-cutting decisions. It is a keyboard worth considering if the Stream Deck functionality is essential to you, but it is not a product that will appeal to everyone.
