This is interesting. How much would you be willing to pay for a replacement, and how often?
Which tools do you use right now for this?
How often should a new tool check for changes? Does it have to be every hour or minute, or can it be once a day, or once a week, maybe?
I'm building my own, as a long-term investment. I paid €10 per month for Wachete but it did not quite do the job. At some point one website was rate-limiting it, so I lost access to a lot of my watched pages. Above all, configuring things by clicking around was a waste of time. I have like 100 pages from the same website to watch.
In my case, once a month is fine.
Ah, I see. So if I built an alternative for $9 a month, you wouldn't use it?
