Ask HN: Social media publicize in a cheap and cloud way

I was searching some way to publicize my blog article. I was searching a simple solution, not necessary free, to integrate with social media. In the past days I tried Zapier, Microsoft Power Automate and IFTTT (f this, then that).

My budget is around 5 euros/month given the simple task (I could be able to do it on myself but I will need to register on the various services my library, be careful not to get banned etc). So a ready-made solution seems a good idea.

I am not an expert on this field but I was shocked by the cost of Zapier and Power Automate, given the complexity to do simple things like publicizing posts or creating keyword alert.

I know they are complex tools but...

IFTTT seems more focused, easy to use and cheap so the question is: what do you suggest for this task?

There is some open source library I can mock or IFTTT is a good candidate? Did I miss some other option? Thank you!
