Platform apps need real engineering, not just clicks.
A serious Salesforce app, especially an AppExchange product, needs
Apex engineering, security review readiness, packaging discipline,
and CI/CD. Click-built prototypes don't survive scale or the
security review.
Engineer it like a product.
Source-driven development with SFDX, test coverage, code review,
CI/CD, and the packaging and security-review discipline AppExchange
requires.
Apps that scale and pass review.
Custom apps that hold up under load and AppExchange packages that
clear the security review.
