This looks great for simple projects, but I'm curious who is working on projects small enough to not be worth a separate dedicated and feature-filled frontend (ala JS/Flutter), but large enough to warrant server-side logic. That's certainly not to say they don't exist, and Pushup is certainly filling a niche, but my mind immediately goes to those "forgotten" services like email unsubscription and confirmation links.
