Is there some nodes for a similar automation like Zapier that is cheaper?

Is there some nodes for a similar automation like Zapier that is cheaper?

Yes node-red itself.

There are many types of no/low-code applications. Zapier uses apps to provide the input (ie. apps provide in/output, usually done via API's). Node-red can do the same, but more broadly/versatile - but might come at a cost of complexity, where Zapier might be more focussed.

What are you looking for exactly ?

Thanks for your reply.
I like to add new event in google calendar. But the google calender node is almost impossible to setup (for me :grinning: )
