First, remember that STEEM is the blockchain on which several apps are built. First, there's Steemit.com, which is the main front-end to the blockchain, however, there are many other apps and projects that have been built on top of the STEEM blockchain and allow everyone to earn rewards to their Steemit account.

These include DLive.io, DSound.audio, Utopian.io, Musing.io, Busy.org, Steepshot, ESteem, DTube, and many others.

It is important to remember that all of these allow rewards to be generated in STEEM. If you're looking for other platforms like Steemit, I'm not sure there are many that are active so far. There's one I've heard of called Sola.ai, but I'm not sure how successful it has been.

Which steam platforms can produce?
when questionable platfrorms are generating so much but I give little information about the steam that really contributes to its users either directly or indirectly. Steemit is now in the midst of a world community that is soaring upwards always.

Coming to your question directly that first you should know steem is a blockchain where there are many other platform so the question should be ,

Any platform under steem where one can earn ?

Yes there are platfrom like dtube, dlive, musing, steem followers, Busy.org etc and new platform which is recently launched name function.io which is good to see you can go to site and look after it.
