CanIRun.gg review
Free browser checker that grades hardware against game requirements across PC platforms.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CanIRun.gg is a free, browser-based game compatibility checker for people who want to assess whether a computer, gaming laptop or handheld can run a game. It detects a GPU through WebGL and reads CPU logical cores and available memory through browser APIs, while also allowing manual hardware selection. The service compares the selected system with minimum and recommended requirements, then assigns an S–F compatibility grade. Its catalog includes Steam games alongside listings for desktop PCs, handhelds, Mac, Linux and Proton compatibility.
There are no subscriptions or paid tiers, so every listed capability is available without a purchase or account. The central catalog section displays 14,520 games, with hardware requirements used for the comparison workflow. For cross-platform players, the inclusion of Linux and Proton listings, Mac compatibility, and gaming-laptop and handheld lookups broadens the service beyond a basic Windows desktop checker. Its web-only deployment also means access starts in a browser, without a download requirement.
Setup is designed around either automatic browser detection or manual entry. Automatic results depend on WebGL and browser APIs exposing the relevant GPU, CPU-core and memory information; manual selection provides an alternative when those readings are unavailable or need adjustment. CanIRun.gg suits solo and small-scale users who want a quick compatibility reference across several gaming platforms. It is less suitable for anyone seeking a native desktop utility, support beyond documentation, or capabilities outside the published game catalog and requirement comparisons.
