literally every app they need, except the browser, at least have 10 alternatives that are FOSS, much more mature, better structured and prone to be bug free... or do you really think the OP with months/years of use won't need some other feature and will re-invent the wheel on software that is around for more than a decade with hundreds of bug reports done (i3 wm was released in 2009)
As a hobby, normal rates don’t apply, but just not to be misleading on the equivalent cost.
I've spent two weeks with the cheapest tiers of Claude Pro + pi.dev+GPT-5.5 (+ some deepseek-v4 via openrouter recently) to create my own bespoke version.
I'm at 90% feature parity currently and surpassed on some levels. For ~20€-ish I've soon replaced a 60€/year subscription service.
I haven't spent a single second thinking about how someone else might run it, it doesn't have logins, security or anything - because I'm going to run it 100% behind a Tailscale node with no external access. The release and deployment processes are exactly how I like it, other people might not. I don't need to care, it's mine =)
A few months ago I did the same with Hazel[0]. That took maybe one evening to get an MVP and a week of casual updates to make it pretty. Now I have my own macOS application that does the exact things I needed Hazel for. It's mine forever and I can add or remove features as I feel like it.
