Uhm shouldn't that be ovious by reading the high level descriptions of each? They are for completely different use cases. Membase is a distributed Key/Value server and LevelDB is a Key/Value library.

Hi there! I'm a YC alum (reMail W09) and helped Jeff and Sanjay with LevelDB. Let me know if you have any questions about LevelDB and I'll see if I can help.

Yes, we put up the Google Code site incognito mode back then, but have since added a number of bugfixes and optimizations, so we're actually comfortable announcing the project now.
