## What it is
OpenSpeedy is an open-source game speed controller for Windows that lets users speed up or slow down running game processes via global hotkeys and a slider. It works purely in user mode by hooking Windows time APIs, with no kernel driver required.

## Use cases
- speed up single-player games
- slow down a game to practice difficult sections
- adjust game speed on the fly with hotkeys
- target a specific running process and change its time perception
- run a free alternative to Cheat Engine speedhack

## When to choose
- you want a free, open-source game speed modifier on Windows
- you need both 32-bit and 64-bit process support
- you want a tool that doesn't install kernel drivers
- you prefer a modern GUI with multilingual support

## When to avoid
- you play online multiplayer games where speed modification is cheating and may get you banned
- you need speed control on Linux or macOS
- you need memory editing or other cheat features beyond speed
