I've built a niche Ghidra extension that managed to form a userbase. Haven't put much effort into publicizing it, it just kinda snowballed on its own through word-of-mouth. In fact, I keep stumbling into Discord forums where I then learn that I had users there that I've never heard about before.

Word-of-mouth happens when someone who has a need finds your project, uses it and likes it so much they talk about it to other potential users. It's effectively a chain reaction and the way to leverage it is to make something people want to use.
