I recently created a web application for curating one big shared public knowledge base.[1] Its contribution system is conceptually based on GitHub's pull requests and StackOverflow reputation. It's focused on tips for learning resources, so it seems ideal for your cheat sheets. Currently, creating lists of SDKs, tools, etc. is not very well supported, but we are working on it. And I already use it for these things, see for example my list of Flutter libraries.[2] I guess it's also kind-of similar to Trove, but it is more focused on creating one curated catalog of knowledge rather than personal recommendation lists (although that is also possible now via personal study profiles, e.g., [3]).
