Make

Quite some technical knowledge needed, better pricing than Zapier

Make is quite awesome. It sits between Zapier and N8N in terms of how technical you should be to operate it. That means you should be a little more technical with Make. If you understand some scripting and need a nice visual way to build workflows, Make might be for you. The audit trail of successful and failed runs is very helpful for keeping track of what work has been done and what hasn't. Pricing of Make is better at the time of writing than Zapier.
