Any Free Social Media Tools to manage & post to multiple Accounts ?

BHW's

Is there any free Alternative to manage and post in Facebook, Twitter or other Platforms from multiple Accounts ?

I have around 30 Accounts already setup with Pictures, now i need them to post in my manually joined Groups.

Any Help appreciated!
Thanks

Hootsuite. Buffer. Tweetdeck (Twitter only).

Yeah, I use all of the above. Works well for me! I bet theres so many more tho
