Question 1

Is CodePreviewer free to use?

Accepted Answer

Yes, CodePreviewer is 100% free and open. Our mission is to dismantle developer bottlenecks by providing premium, offline-safe coding tools completely free of cost.

Question 2

Is my code secure? Does it upload to any server?

Accepted Answer

Absolutely not. Privacy and security are critical. All processing, parsing, and rendering (HTML, XML, JSON, URLs) happens entirely client-side inside your own local browser environment. No raw code ever touches a remote server.

Question 3

What is Vibe Coding and how does this site help?

Accepted Answer

Vibe Coding is a modern coding style where you guide AI agents (like Cursor, Bolt, or ChatGPT) using natural language prompts to write software. CodePreviewer serves as the perfect validator, allowing you to instantly inspect and test generated UI blocks without having to setup heavy local environments.

Question 4

How does the JSON/XML validator display syntax errors?

Accepted Answer

Our tools utilize standard browser parsers. If a parsing exception occurs due to mismatched tags or trailing commas, the UI intercepts the error stack and displays the precise syntax location, helping you patch it instantly.

Question 5

Are the guides and tutorials of high quality?

Accepted Answer

Yes. All guides, tool reviews, and prompt libraries are authored by the CodePreviewer Team, adhering to high-quality international standards and promoting secure, accurate coding practices.
