Half-Life Server Watch (HLSW) is a game server browser and administration tool written by Timo Stripf. HLSW was originally designed with a focus on administrating and joining Half-Life servers (pre-Steam) thus the name, Half-Life Server Watch. However, over the years, HLSW has added support for other games and modifications.
