Two months with v0: what is fast, what is frustrating, and where I lost time

An honest, unsponsored review of strong use cases, dead ends, and my current workflow.

I use it for prototypes and interfaces when validating an idea quickly matters more than perfect first-pass code.

What works in practice

• A first working flow appears in hours rather than days.
• Read the code after two or three iterations.
• Define visual constraints before the first screen.
• A new prompt should not patch the consequences of the previous one.

Where the boundary is

The most expensive mistake is endlessly fixing one prompt with another. The project loses coherence while the model patches the consequences of its own decisions.

The short conclusion

The best mode for me is to use v0 as a fast interface partner: provide a system and constraints, then make the product decisions by hand.

The short conclusion

v0 dramatically shortens the path to a first interface, but it does not replace product judgment, taste, or engineering discipline.
