Oh, super cool! I'm glad you shared that, I was thinking of building out something similar so you just saved me a lot of time.
I've recently begun blogging and I was recommended posting across different platforms while setting the canonical URL to my personal blog for increased traffic.
I don't see a reason not too, so I plan on posting to as many places as I find so long as it's convenient.
After watching CrossPost's video, it doesn't look like they support actual cross-posting to blogging sites and simply posts links to social media sites like FB, Twitter, Reddit, and LinkedIn.

I was not sure. So I tried the trial.
I posted one of my Medium articles to Hashnode.
It actually did post the article.
It's not a perfect and polished UI but did the job.
