Preview a complete frontend file
Paste a self-contained HTML document or a focused snippet with its CSS and JavaScript. The preview refreshes in an isolated frame, so you can test an interaction without installing dependencies or configuring a local build.
Turn the current result into a review link
Give the work a descriptive title, test the important path, then publish a stable link for a teammate, student, or client. A shared preview communicates behavior that a screenshot cannot show.
Remove private data before publishing
A sandbox separates the preview from the ShowYourCode session, but a public link is still public. Remove access tokens, customer data, internal URLs, licensed assets, and production source that you do not have permission to share.
Check more than one viewport
Use the desktop, tablet, and mobile controls to find overflow, cramped controls, and unreadable type. Also test keyboard navigation and browser zoom before asking someone else to review the result.
Start with a reviewed example
Choose a template when structure matters, read the safety guide before sharing unfamiliar code, or browse curated work to compare implementation choices.
