I build small tools and bots for fun, and lately a lot of my work involves posting content automatically across different social platforms.

I was using a basic script for one platform, but it broke every time that platform changed something.

So, I wanted an API that could handle posting and scheduling across more than one platform, without babysitting tokens and rate limits all day.

I tested seven social media scheduler APIs. I connected real accounts, wrote actual code, and scheduled actual posts to see what broke and what worked.

Here is what I found.
