How to Choose a Vibe Coder and Check Their Skills Before Paying
A client checklist for questions, evidence, trial tasks, and red flags before committing to a large payment.
In brief
- • A strong vibe coder can explain what they built and what they intentionally left out.
- • Check a live result, personal contribution, project constraints, and testing method.
- • A trial task should be paid and limited, not free production work.
- • Before payment, define ownership of the repository, environments, and accounts.
- • Escrow and milestones reduce payment risk but do not replace acceptance testing.

Checking a vibe coder is harder than checking a conventional developer because a polished demo can be produced quickly while quality appears later—in error handling, permissions, data models, and production behavior. Your selection process should test the ability to deliver a safe result, not only the ability to make a screen look finished.
Questions to ask before signing
- How do you understand the product goal and the main user flow?
- Which parts would you not automate immediately?
- How do you review AI-assisted code?
- What risks do you see in authentication, payments, and personal data?
- What should be working after the first week?
- Which access permissions do you actually need?
A strong answer contains questions and boundaries. “AI will build everything and we can launch in two days” is not evidence of skill.
What to check in a portfolio
Open a live link on both a phone and a desktop. Look for real states: empty data, form errors, repeated submission, password recovery, and role differences. Ask which parts the candidate built personally and which parts came from a team or client.
A useful case includes the goal, constraints, decisions, timeline, personal contribution, and what happened after launch—not only screenshots. See the VibeMarket portfolio guide for context.
How to run a small trial
Choose a narrow part of the future project: a form screen, one API method, a test-file import, or a data-model sketch. Provide limited context and ask the candidate to:
- write a short plan;
- name questions and risks;
- show the result in a separate environment;
- explain how it should be tested;
- hand over a short note.
The trial should be paid. If the result can enter production, define ownership separately.
Red flags
- the candidate asks no questions and promises everything without limits;
- the portfolio contains only images and no live results;
- there is no repository access or clear account ownership;
- the developer cannot explain how to roll back a change;
- full payment is required before the first demonstrable result;
- every failure is dismissed as “just an AI issue.”
How to structure payment
Split the work into checkpoints and link payment to verifiable outcomes. You can start with a VibeMarket project request and review the guide to escrow-protected payment.
How to check the quote before paying
Match the price to the full scope: a simple landing page often falls around $300–$1,200, a bot $250–$2,000 depending on flows and integrations, and an MVP $2,000–$10,000. If the quote is higher, ask for concrete engineering reasons such as roles, payments, security, migrations, monitoring, or support.

Bottom line
A vibe coder’s skill is not the speed of code generation. It is the ability to make engineering decisions, verify the outcome, and state where automation stops.
