No matter how many niceties you put on flow-based programming, the tools I had to use (all serverless) were the wrong ones for the job, and management was unreceptive to feedback (they wouldn't even give me a github repository).
I think Tines has potential but it's going to have to invest more into mitigating its shortcomings, not just further improvements on what it already does well. For example, as of March 2021, it was still far too easy to misclick and break something in production with no confirmation. You could export your setup as json, but IMO there was too much friction/manual work with that approach for it to be useful. To be fair, the company was pretty early stage at the time, maybe it's improved since then.
I don't blame Tines for what was the worst job I ever had (which I still have nightmares about to this day), but maybe someone else can be avoided the same fate with this feedback.
