I'm not sure what you mean re: ScrapingBee being expensive. I am scraping some pretty heavy pages and it's costing about a half of a cent for a page. Less again with OpenAI. All-in-all, maybe sub 1c per page. Maybe there is more you are doing with this CRM creation process you have.

Right now in terms of open source or SaaS ... I think it is likely at some point I will replace ScrapingBee, maybe even OpenAI, with my own version of these and then take it down to a single API key and bill users myself. However I am leaving it free (albeit with BYO keys) for the moment as I am still building things out. I will likely continue to offer free to those who were already using it before I switch to a different model.

As mentioned, this is just the beginning of this project. The next features include logging in to accounts, giving instructions, so that ideally you can say things like 'book me a uber for 3pm to take me home from work', and the API gets it done and returns you the confirmation and whatever else you asked to be returned.
