🙋 Frequently Asked Questions (FAQs)

Do you send my JSON payload or API keys to any server?

No. TechWicket runs client-side JavaScript execution via standard native APIs. Your code remains 100% private in your browser.

Why am I getting a syntax error on single quotes?

Standard JSON specification rules require keys and string values to be enclosed strictly in double quotes ("), not single quotes (').
