- Worth noticing
- Its example timeline combines a TLS certificate, a vendor API retirement, package health, and a manually entered license renewal.
Field notes
The homepage lists four manifest formats for package checks and says users only need to enter dates that are not published elsewhere. Its example timeline includes a vendor API retirement matched to a dependency, plus an owner and status for each item. The site advertises daily domain checks, certificate checks every 12 hours, and package checks daily; these are product claims rather than independently verified results.
