Legacy JavaScript

Est savings of 11 KiB

Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support older browsers. Learn why most sites can deploy ES6+ code without transpiling

Render-blocking requests

Est savings of 1,310 ms

Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.

01 / WHAT WORKS

What makes it work

Distinct typographic personality and brand contrast

The hero heading pairs heavy sans-serif glyphs at 72px with Caveat script styling and an orange accent underline (#ff5500), anchoring character without sacrificing legibility.

Immediate domain credibility via reference showcase cards

The showcase grid directly renders recognized design benchmarks like Cursor, Lovable, and Stripe alongside live palette swatches and monospace domain tags.

02 / NEXT STEPS

Where to go next

  1. 01

    Add an instant audit report preview tab beside the input

    First-time visitors do not know whether '深度审计' yields a score, CSS variables, or an AI prompt, causing bounce before trying.

    Place a prominent '查看示例报告' link or interactive toggle below the input that previews an audited report with token metrics and prompt snippets. Verify that clicking it reveals modal or inline sample data across 1440px and 390px viewports.

  2. 02

    Turn curated gallery cards into one-click test runs

    Typing a URL on mobile or finding a reference site on desktop is high friction compared to tapping an existing showcase card.

    Make every showcase card clickable with a visible '试运行' badge that injects the target URL (e.g., linear.app) into the hero input and initiates analysis immediately. Verify the input fills and status loader triggers on both click and tap.

04 / EVIDENCE

The detail behind the report

Explore each observation, recommendation and captured record.

Conversion6 observations

Share card is incomplete

High

A blank or generic unfurl on X, Slack, or WeChat wastes the click you already earned. This is distribution, not decoration.

Set og:title, og:description, and a 1200x630 image that matches the live headline.

og:title=yes og:image=no

A form has no action

High

A waitlist or contact form with no action is a conversion dead end. It looks ready and does nothing.

Wire the form to an endpoint, Formspark, Basin, or a server action you actually handle.

<form>

No human or proof on the page

Medium

A stranger landing on an AI-looking site with no maker, no customer, and no contact will not give you an email.

Add a real name, a real face, a real contact method, or one real customer line.

no about, no first-person, no quote

No analytics on the live page

Medium

If you cannot see who bounced, you cannot tell if the next fix worked. Shipping without a counter is flying blind.

Put Plausible, PostHog, or GA4 on the public pages. One snippet is enough.

no gtag / plausible / posthog / umami

No way to reach a human

Medium

A stranger who wants to buy, ask, or complain has nowhere to go. That is a conversion leak and a trust leak.

Put a mailto, a form that works, or a real social handle in the footer. One is enough.

no mailto / telegram / x / github / email

Tab title and H1 disagree

If the tab, the share card, and the hero name different things, the visitor cannot form one memory of the product.

Make title, og:title, and H1 share the same noun.

title="VibeCheck · 网站气质检测" h1="从 Vibe 到专业"
Launch4 observations

No HSTS header

Medium

Without Strict-Transport-Security, a first visit can still be downgraded to http. Browsers will not pin HTTPS.

Set Strict-Transport-Security: max-age=31536000; includeSubDomains at the edge.

strict-transport-security missing

No Content-Security-Policy

A CSP is the standard way to limit script sources. Vibe-coded pages often load anything, including injected scripts.

Start with a report-only CSP, then default-src 'self' and an explicit script-src.

content-security-policy missing

No X-Content-Type-Options

Without nosniff, browsers may interpret a file as a different type than you sent. It is a one-line header.

Set X-Content-Type-Options: nosniff.

x-content-type-options missing

No Referrer-Policy

The default referrer can leak internal paths and query strings to third parties.

Set Referrer-Policy: strict-origin-when-cross-origin.

Preview full instructions
Enhance the VibeCheck hero conversion flow while preserving exact design tokens (#fafafc background, #0b0f19 ink, JetBrains Mono tags, 7px button radius, 10px card radius, and Caveat font on 'Vibe'). 1. Add an interactive '查看示例报告' preview trigger beneath the URL input that displays a sample audit card showing scores, extracted palette swatches, and a copyable DESIGN.md prompt snippet. 2. Make each gallery card (Cursor, Lovable, Stripe, etc.) interactive so clicking it injects its URL into the input field and executes the audit. 3. Maintain responsive padding, header layout, and mobile navigation behavior. Test at 1440x900 and 390x844 viewports to verify alignment and focus states.
