We also do this at windmill: https://github.com/windmill-labs/windmill
If I'm reading correctly, to build features on top of Windmill requires the commercial license even if self-hosting which comes with a price of $.002/ computation where a computation is 1 second of processing on 1 CPU with 2GB ram.
One of my main usecases would be to create flows to pull data from various sources. The speed of such processes often depends on the 3rd party APIs - so it wouldn't be unheard of for a process to take 30+ min to pull a bunch of data where much of the time is spent on data transfer or waiting for the service. Does that mean it would cost me .002 * 60 * 30 = $3.60 for one 30 min data sync? That's not including any downstream etl I might do that would potentially multiply the cost. Curious if that's accurate or if I'm misinterpreting something.
Your calculation is correct and I agree it is a bit of a steep pricing. Most companies have small scripts to run and we wanted to bill according to the value they were extracting of the product and do transparent enterprise pricing instead of the usual "contact us". Unfortunately, it is not a one-size-fits-all situation. For data heavy/IO bound workflows, we should bill per number of GB transferred rather than per computation. In any case, we are very open to do price capped contracts depending on your use case: ruben@windmill.dev
I'm doing some more research but will keep ya'll in mind and reach out if I have more questions!
