of course, I'd be happy to tell you the difference
CNOE is already a tool, whereas what I'll provide is a framework to build tools.
The problem with pre-made tools is that they already dictate the tech-stack you need to use, CNOE integrates with argocd and backstage and a few pre-defined tools that you must use in order to use CNOE. Also, customizing it would mean customizing the main tool.
HAPE Framework will provide you with the framework to build CLI and API tools. Suppose you want to extract data from kubernetes api, and save it to database, you have to create this functionality from scratch. Whereas if there is a framework that auto generates the models, controllers, argument parsers and api controllers, and that already has a kubernetes client integrated with kubernetes. Then all you have to do is generate the MVC files and you'll have a cli/api ready to use.
Same if you want to extract data from git (github, gitlab, bitbucket) and prometheus and AWS and process them and save them in one table in the database. You'll have to start development from scratch, but with a framework you can save a lot of time building the database and integrations.
HAPE Framework is used to build customized automation tools with ease. However, it's not an automation tool, it's not like CNOE or any other available automation tool in the market, because it's not a tool by itself.
