Ask HN: What do you use to track website changes?
What SaaS service or self hosted tools do you use or recommend for monitoring and being notified when website content changes?
Currently I use acrchive.org which is far from what you and I are looking for :(
Ideally, I could submit URLs for monitoring with an authenticated API call, could receive both email alerts and webhooks on modify, and there would be an option to have the Internet Archive archive a copy when a modification is detected (and possibly attach a WARC file of the http request/response when a modification was detected).
