SpeedTool review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

SpeedTool is a downloadable desktop timer for speedrunners who want timing tied to a game's frame output rather than a separate timer window. It runs inside a target game, supports nested subsplits, and lets users write Lua scripts in a sandbox. The product is free and has Windows and Linux builds, making its core timing approach relevant to solo runners who want game-specific timing behavior. Its support for OpenGL, DirectX 9, and DirectX 11 defines the graphics environments it covers.

The standout feature is the synchronization between script execution and game frames. That gives runners a basis for building timing scripts around a game's output, while nested subsplits offer a way to organize run segments. Lua scripting is currently supported only on Windows, however, so Linux users can access the Linux build but not that scripting capability. SpeedTool is a closer fit for runners comfortable with a script-oriented approach than for anyone seeking a timer that requires no game-specific configuration.

The developer describes SpeedTool as a work in progress, which is important for runners considering it for an established timing workflow. The official page does not describe a built-in leaderboard connection or a catalog of supported games, so runners should not choose it expecting either of those features based on the published product description. Its narrow focus is frame-synchronized in-game timing rather than a broader speedrunning platform. Choose SpeedTool if that timing model and its supported graphics platforms match your game and you are comfortable with its current development status; look elsewhere if Windows-only scripting is a blocker or leaderboard connectivity is essential.
