The Six Pillars of a Good Web App — And How to Enforce All of Them in a Single Lovable Prompt

Most web apps get two or three of these right. The good ones get four. Very few ship all six from day one. Design. Security. Performance. Reliability. Privacy. Accessibility. These aren't separate concerns you address in separate sprints. They're the same concern: building something that actually works for the people using it. Here's what each pillar means in practice, how to bake all six into a single Lovable prompt, and how to stress test them before you ship. The Six Pillars 1. Design Not aesthetics. Not a color palette. Design is the absence of friction — intuitive navigation, clear hierarchy, interfaces that don't make users think. A well-designed app communicates trust before a single line of copy does. 2. Security Auth flows that don't leak. Input validation that doesn't trust anything. Data protection that assumes breach. Security isn't a feature you add at the end — it's a constraint you build inside of from the start. 3. Performance Speed is a feature. Scalability is a promis
