Your app exists. That is the starting line.
v0 is strong for creating interface direction, but a good-looking UI is not the same as a product that works. The next step is testing the real flow, data behavior, and user comprehension.
The useful next step is not more polishing in private. It is putting the real product in front of people with a clear task and learning from what happens.
Run a readiness check before traffic
- Open the live URL on mobile and desktop.
- Confirm signup, login, payment, data saving, and key flows work outside the builder preview.
- Remove obvious placeholder text, unsafe test data, and broken navigation.
- Confirm the interface has real destinations, working forms, durable state, and production wiring beyond the generated visual shell.
Choose one proof task
For a v0-built product, test the moment where visual design becomes usable product behavior: submission, creation, checkout, onboarding, or completion.
Use evidence to decide
- 01Made
You used the builder to ship something people can reach.
- 02Prove
Let unbiased usage test the assumptions behind the product.
- 03Decide
Keep going, improve a specific point, or stop investing based on evidence.
