yes I find Many website like api.steem.place just search about steemit api posts you will find many tools can help you build things easly , i was thinking to make a little program , alert me when my favourits steemians post something , because the feed at steemit it's not useful if you follow many people u will missed many posts ^^ , so i can check number of posts for example :

https://api.steem.place/getPostCount/?a=libertyteeth

if posts number increase Then new post is posted & alert me :)
