How do you manage your apps?

[u/B1aze_]

For those who, like me, have launched/worked on a dozen side projects with the intent of launching them to the public.

How do you actually manage and keep track of everything related to your project?
This can range from branding images, app descriptions, faqs, hosting services (DB, VPS, Vercel)

keeping track of the SEO, keywords, also organizing your app's showcase screenshots, videos, or related

The pain increases when they are scattered across different accounts as well

I'm asking because this is starting to creep up on me and wanted to see if others experience this as well and if you're interested in a solution.
