About Steam Achievement Manager
Steam Achievement Manager, commonly known as SAM, is a focused Windows utility for managing achievements in Steam games. Through the SAM Picker interface you select any title in your library and open a window to review, unlock or relock its supported achievements one at a time.
SAM is free and open-source, distributed under the zlib license and written primarily in C# by independent developer Rick Gibbed. The full source is public, so the application can be inspected or compiled yourself, and it is not affiliated with or endorsed by Valve.
Beyond unlocking, SAM can relock achievements for a clean playthrough, display recorded unlock times, and view and edit the integer and floating-point statistics a game exposes. Selections stay pending until you choose Commit Changes, so nothing is applied silently or in bulk.
The tool is portable — extract the ZIP and run it from any folder, no installer needed. It requires the Steam desktop client to be running and signed in, works only on Windows, and interacts with achievement data locally rather than through an external service.
