Overview

SignalRGB is Windows software for synchronizing RGB lighting across devices, and it is best suited to PC owners with hardware from several supported brands. Its free tier covers lighting and a modest set of cooling and macro tools; users who want deeper tuning will need Pro.

Key features

SignalRGB advertises support for more than 6,000 devices, including products from Razer, Corsair, SteelSeries, Logitech, and MSI. It offers addressable RGB control, cross-device synchronization, lighting profiles, and game lighting effects. That cross-brand scope can simplify a mixed setup, but compatibility with your specific devices is central to whether the software is useful.

The free library includes hundreds of customizable effects. Pro offers a larger content library: 250+ RGB effects, 45+ game integrations, 20+ audio visualizers, and 20+ LCD screen themes. Integrations include Valorant, Apex Legends, Minecraft: Java Edition, Counter Strike 2, League of Legends, and Fortnite. The breadth will appeal to users who want lighting tied to games or audio, though the expanded library requires a paid plan whose price is custom pricing.

Free users get five built-in fan curves and basic monitoring. Pro adds custom multi-point fan curves and unlimited cooling profiles, along with customizable monitoring widgets, adjustable size and position, expanded sensor options, and a 24-hour lookback. Those controls are more useful to people who actively tune and monitor a PC than to users seeking lighting alone.

Free includes two macros; Pro allows unlimited macros and macro profiles. Pro also includes ad removal, a mini player, a local API, and LED color tuning. Some users who have never had Pro may qualify for a free trial, but signing up requires a valid payment method.

Pricing

SignalRGB uses a freemium model. SignalRGB Free is free and includes the standard content library, basic cooling and monitoring, and two macros. It is the sensible starting point for users who mainly want synchronized lighting and can work within those limits.

SignalRGB Pro has custom pricing and includes the full content library, advanced fan tuning, customizable monitoring, unlimited macros, ad removal, a mini player, a local API, and LED color tuning. It fits users who need those expanded controls; the cost is a factor to weigh before relying on Pro-only features. A trial may be available to eligible first-time Pro users, with a valid payment method required.

Light Points has custom pricing. It lets users buy individual effects and game integrations, and purchased content remains theirs without a subscription. That suits someone who wants select additions rather than Pro’s full set of features.

Platforms

SignalRGB is available for Windows.

Who it's for

SignalRGB is a good fit for Windows PC owners whose devices are supported and who want one place to coordinate lighting across brands. Free should cover users focused on effects and basic cooling. Pro is aimed at enthusiasts who want custom fan curves, richer monitoring, or unlimited macros. It is less compelling for someone who only needs basic device configuration or does not need its broader content and tuning tools.

The privacy policy identifies Whirlwind Virtual Realities Inc. as the company and data controller. It says SignalRGB collects hardware and technical information, including device specifications, operating system and software versions, IP address, and app performance data. The policy describes encryption in transit and at rest, regular security assessments and updates, access controls, and certified payment providers. The contact page cautions that technical support responses may be delayed because of high ticket volumes.

Pros: The free tier includes hundreds of effects, five built-in fan curves, basic monitoring, and two macros.
Pros: Pro combines expanded effects and game integrations with advanced cooling, monitoring, and macro controls.
Cons: Pro's price is custom pricing, so users cannot readily compare its cost with the free tier's benefits.

Cons: Support may be delayed during periods of high ticket volume.

Verdict
