Ask HN: Are non-collaborative, non-realtime web software looked down upon?

I have a neat little idea for a product that I have wanted to build for quite some time. Basically, its a personal tool (in the same vain as excel) that runs in your own computer. A lot of it has to do with form building and CRUD operations (along with pre-save, post-save signals). However, everywhere I look these days, everything is realtime, collaborative and always on. I simply do not have the team/energy/money/skills to pull off something like that. Are tools like the one I described (single user based, runs on your computer with a local db) looked down upon these days?
