I know of a few products that are related: - DavidDM (https://david-dm.org/) does dependency checking - Snyk (https://snyk.io/) does vulnerability checking - Blackduck (https://www.blackducksoftware.com/) does everything, but it's heavy, not hosted, and expensive.
I was thinking about building one myself if I can't find something out there. Would anyone else use it? Node.js and Bower support first, others later.
