MasterPlan is a customizeable graphical project management software for independent users or small teams. If you need to share plans across a whole company on an online platform, there are quite a few tools for that. However, if you want to keep track of your todo list, version control your project plan, make an ideaboard, and plan your project your way, MasterPlan is the tool for you. Note that this is the code repository and external issue tracker for MasterPlan; actual releases can be purchased from itch or Steam. You can also just build it yourself from this repository if you're familiar with Go.
