One of the biggest goals of mine is to keep FrogPilot 100% free and open for the openpilot community to use. But as the FrogPilot community grows, that gets harder to maintain as said community uses up more and more resources. So instead of paying out a bunch of money out of pocket, I have a “tip jar” to help pay for the running costs and any left over funds gets handed back to the developers who make this project so damn great!
