Buffer

Buffer is a social media management tool that lets you create, schedule, and publish content across all your profiles from one place. It's built by the company of the same name, one of the longest-running brands in this space, and it's aimed mainly at creators, small business owners, and personal brands who want to post consistently without the chaos.

It works simply: you connect your social networks, write a post, pick the platforms and publishing time, and Buffer handles the rest. You arrange posts in a clear calendar, see what's coming up in the next few days, and Buffer measures the reach, engagement, and performance of each post for you.
