Ask HN: How do you validate your business idea and find key competitors?
This is effectively the same as DOKS one-click apps, but slightly better because you don't have to manage infrastructure (we, or as of right now, I do, theoretically speaking), but I'm also sure somewhere someone else just did what I did better. It's more like a traditional PaaS (say like Heroku and fly.io) but having some SaaS elements (cloud offerings) as well.
So, how do you validate the feasibility and justify for this product idea, and how do you find more competitors that already done what you do so that you don't reinvent the wheels?
