We see a lot of hype around "Vibe Coding" lately (just prompt it, and AI builds it).

As someone with 20+ years in tech, I see a dangerous pattern:

1. It works for the "Happy Path" (Simple prototypes).

2. It fails at "Edge Cases" (Security, Scaling, Database integrity).

Let's talk about unit economics.

If you wrap OpenAI's API and charge a flat $20/month subscription:

- You lose money on your best customers.

SaaS founders often ignore mobile apps because of the development cost (Flutter/React Native) and the complexity of App Store approvals.

But retention data doesn't lie: A native icon on the home screen increases LTV (Lifetime Value) significantly compared to a browser tab.

With Blyxxa, we implemented TWA (Trusted Web Activity) to turn WordPress SaaS sites into native .AAB files instantly.

For indie hackers: Is a mobile app a "must-have" or a "nice-to-have" for your MVP?
