Open Bluewing GUI Server (OpenBGS) is a free, open-source app to host your own server using the Lacewing Protocol. OpenBGS is good if you want to host a Lacewing server for multiplayer games made in Clickteam Fusion. This tool is suitable only for small or medium-sized community servers. For long-term hosting, use Bluewing C++ Server made by SortaCore (Phi). This app was previously OpenBRP. Now, here is a new, improved version
This is how the app looks. It is also made in Clickteam Fusion, so expect false positives.
OpenBGS is also available on Gamejolt or on Github
