Help Me Pick My Next SaaS Product!

So I've got two developer tool SaaS products in mind:

The first I call "Darkhouse": you enter your site URL and I use results from Google Lighthouse to give you developer-specific line-level (or even character-level) changes you can make on your site to improve it's Lighthouse score (i.e. SEO and speed score, as well as accessibility and more)! I love Lighthouse, but you often have to drill down into the documentation to correct whatever it is complaining about. I would do that for you and apply it to your codebase so it would be a 5-second change.

The second I call "Reduxplate" - you pasting in your Redux state shape and initial state values, and it generates all the actions, types, and reducers you need for your Redux store! This takes tools like Redux Toolkit a step further in the level of abstraction. I would also add multiple options, like if you want the store as a single file or the community standard actions / types / reducers as separate files, as well as a pure JavaScript or TypeScript style output. A .zip file download would then start immediately for you to use!

I like both of these ideas a lot, and may end up building both of them... but which one should I build first?

Both ideas are on Kernal, if you use that platform:

I started using Kernal after Channing's recent email that mentioned it, I think it's pretty cool :)
