Studomate is described as 'Free, open-source browser tool to edit and simulate GRAFCET and Ladder logic together, with animated HMIs connected via shared variables' and is an app in the education & reference category. There are five alternatives to Studomate for Windows, Linux and Web-based. The best Studomate alternative is CODESYS. It's not free, so if you're looking for a free alternative, you could try CODESYS or PLC Simulator. Other great apps like Studomate are Automgen and ClassicLadder.
CODESYS is the leading manufacturer-independent IEC 61131-3 automation software for engineering control systems. It is used to program many hundreds of different controllers, PLCs, PACs and other automation system, even via an Industry 4.0 interface.
