The site speaks fluently to a tiny audience of systems programmers and says nothing to everyone else — while a rendering failure makes two-thirds of the page invisible to both humans and search engines.
ClarityFail 30/100
Technical jargon and missing content render the page inaccessible and incomplete.
The hero section speaks exclusively to systems programmers using terms like RISC-V, JIT, and emulation without ever establishing why a general visitor should care. The page assumes deep prior knowledge and offers no translation layer for anyone outside that niche. Combined with a structural rendering failure that leaves two-thirds of the page as black void, the overall experience signals incompleteness and exclusion.
A visitor landing here cannot answer: "What does this do?" or "Why would I use it?" The terminal demo, while technically impressive, requires understanding what a terminal is. The stats row (RV64, 2 JIT backends, 1 External dependency, ~15K Lines of pure Rust) doubles down on insider shorthand instead of user benefit. The broken page layout compounds the clarity problem — critical content simply doesn't appear.
Issue 01 of 03
Headline assumes the reader already understands the problem being solved
"RISC-V emulation at near native speed" is technically precise but meaningless to anyone outside systems programming. RISC-V is a CPU instruction set architecture; emulation means running code written for one architecture on another; "near native speed" compares performance to direct hardware execution. None of this lands for a general audience. The headline prioritizes technical accuracy over accessibility.
Rewrite the hero headline to answer "What does this do?" in plain language: "Run software built for different computer processors, without the performance penalty." Then add a one-sentence clarification: "Emuko translates RISC-V instructions in real time so your programs run as fast as if they were built for your machine."
Issue 02 of 03
The page never explains what problem it solves or who should care
There is no narrative. No "Why would you want this?" No analogy to familiar concepts. No description of use cases (running legacy software, cross-platform compatibility, development workflows). The visitor is dropped into an expert conversation with no context. The stats row reinforces the assumption that credentials and architecture details matter more than outcomes.
Add a three-sentence "What is this?" section immediately below the hero: (1) What it does in one sentence. (2) One concrete use case or benefit. (3) Why performance matters here. Move technical details into a collapsible "Under the Hood" section for developers who want them.
Issue 03 of 03
The bottom two-thirds of the page is an empty black void
The "Features" and "Quick Start" navigation links point to sections that either don't exist or fail to load. The page looks broken or abandoned. A visitor sees a headline, a terminal demo, and then nothing but black space where features and documentation should live.
Audit and fix the page rendering. Ensure all sections referenced in navigation are present and visible. Add a "Why Emuko?" section with 3-4 bullet points explaining concrete benefits. Add a "Quick Start" code block showing how to install and run a simple example. The page should not have empty states that suggest failure.
ConversionFail 22/100
Critical rendering failure and absence of low-friction conversion paths eliminate all paths to action.
The page offers only two CTAs — "View on GitHub" and "Quick Start" — neither of which communicates a benefit or value proposition. No email capture, no browser-based demo, no free tier signup, and no newsletter opt-in exist to capture interest at low commitment levels. The terminal demo screenshot showing Linux boot commands is the strongest conversion asset on the page, but it remains static and non-interactive, missing the opportunity to let visitors experience the product directly.
Worse, the page rendering is fundamentally broken: the bottom two-thirds of the viewport displays as empty black space, hiding all six feature descriptions, the step-by-step quick-start walkthrough, and the closing CTA that would normally build desire and reduce friction. Combined with zero social proof — no GitHub stars, testimonials, or "trusted by X developers" indicators — visitors have neither reason to trust the project nor any visible path to take action.
Issue 01 of 03
No low-commitment conversion paths exist
Visitors can only click "View on GitHub" or "Quick Start." Neither communicates value, and both demand high commitment — jumping to GitHub or diving into documentation. There is no email signup, no interactive browser demo, no free tier access, and no newsletter subscription that would allow exploration without friction.
Add a hero-level email capture form with copy like "Get notified of releases." Embed an interactive terminal demo or animated replay so visitors can see the product in action without leaving the page. Add a "Try it Free" button as a primary CTA alongside GitHub.
Issue 02 of 03
Zero social proof destroys credibility
The page includes no GitHub stars, testimonials, case studies, user counts, or "used by" logos. For a developer tool, visitors cannot assess whether this project is mature, actively maintained, or worth their time. The stats row provides only technical specs with zero credibility value for outsiders.
Display live GitHub stars prominently near the headline. Add a line like "Used by X developers." Include maintenance indicators: last-updated date, commit count, or contributor count. Embed GitHub badges for build status, license, and version.
Issue 03 of 03
Broken page rendering hides all mid-funnel content
Six feature descriptions, a step-by-step quick-start guide, and a closing CTA all exist in the markup but are invisible due to rendering failure. The bottom two-thirds of the page is black. This removes every piece of content designed to build desire and reduce friction before conversion.
Debug and fix the CSS or JavaScript causing the black void. Verify the page renders completely on desktop, tablet, and mobile. Render all content as static HTML first, then layer animations on top as progressive enhancement.
ReadabilityFail 35/100
Low-contrast secondary text, an impenetrable terminal demo, and a vast empty void below the fold.
The hero headline and stat numbers are legible, but the page falters on secondary information. The subtitle, stat labels, navigation links, and footer all use medium-gray text on near-black backgrounds — combinations that fail WCAG AA standards and become unreadable on budget displays or in bright sunlight. The terminal demo, while authentic for developers, is an impenetrable wall of unfamiliar text with no visual hierarchy, color differentiation, or annotations.
Most damaging: two-thirds of the page is empty black space below the stats row, leaving visitors with nothing to read after their first scroll. Readability failures directly reduce engagement — users cannot process secondary information, cannot understand what the terminal output means, and cannot find a reason to stay.
Issue 01 of 03
Secondary text contrast falls below readable thresholds
The subtitle, stat descriptors, navigation links, and footer text use medium gray on near-black backgrounds, producing contrast ratios well below the WCAG AA standard of 4.5:1 for normal text. This becomes illegible on non-premium displays, older monitors, and in bright environments.
Increase secondary text to at least #ccc or lighter (#ddd for stat labels) to achieve 7:1+ contrast. Test all gray text against the background using a contrast checker. Apply this uniformly across subtitle, nav, stats descriptors, and footer.
Issue 02 of 03
Terminal demo alienates non-technical readers with no explanation
The CLI output uses monospace text without color differentiation between commands and output, no annotations, and a smaller font than surrounding content. Average users see a wall of unfamiliar text with no guidance on what to focus on, why it matters, or what it proves.
Add a one-line label above the terminal explaining what it demonstrates: "Two commands to boot Linux." Use color differentiation between user input and system output. Annotate the critical line with a highlight. Add a caption below explaining the outcome in plain English.
Issue 03 of 03
Two-thirds of the page is empty black void with nothing to read
After the stats row, the page descends into empty black space with no content, buttons, or calls-to-action. Visitors scroll down expecting more information and find nothing. The page reads as incomplete or broken.
Fix the rendering failure so feature content appears. Ensure each section below the fold has visible contrast and breathing room. Add a clear CTA button near the bottom to capture interest before users close the tab. Every scroll should be rewarding, not empty.
TechnicalWarn 45/100
JavaScript animation failures render two-thirds of page content invisible.
The page stretches to ~3,500px but only the top ~1,500px displays visible content. Feature cards, quick-start walkthrough, and closing CTA exist in the DOM but remain hidden — almost certainly due to scroll-triggered CSS or JavaScript animations that fail to fire. All rendered content (nav, hero, version badge, headline, subtitle, CTAs, terminal demo, stats bar) is technically competent and loads without jank, but core messaging relies entirely on animation triggers that are not executing.
This architecture violates fundamental web design principles. A static landing site for a developer tool has no legitimate need for scroll-triggered reveals of text and code blocks. If animations fail, break, or are blocked by script restrictions, the entire middle and lower page content becomes inaccessible. The site presents as broken to users and renders invisible to search engines.
Issue 01 of 02
Scroll-triggered animations fail silently, hiding 60% of page content
All hidden content exists in the DOM with inline styles like opacity: 0 or transform: translateY(). The animation library or custom scroll event listener is not firing. Root causes may include animation library misconfiguration, scroll event listeners never attaching, animation thresholds set incorrectly, or scripts failing silently on load.
Open browser DevTools Console and check for JavaScript errors during page load. Inspect hidden elements and confirm their opacity/transform values. If using a library like AOS or GSAP ScrollTrigger, verify the library loads, initializes on DOMContentLoaded, and has correct selector/threshold configuration. Replace broken animations with progressive enhancement: render all content statically with default visibility, then apply animations as enhancement.
Issue 02 of 02
Core content depends on JavaScript reveals instead of static HTML
A landing site should never depend on animations to make content readable. If a user has JavaScript disabled, uses a privacy-focused browser extension, or encounters a script error, the page becomes nearly blank. Search engines and accessibility crawlers will see little to no indexable content in the hidden sections.
Render all feature cards, quick-start walkthrough, and CTAs directly in static HTML with full visibility by default. Remove the scroll-triggered animation approach entirely. If animation is desired, layer it on top of already-visible content using CSS keyframes or JavaScript — not as the sole mechanism making content appear.
SEOFail 15/100
Single-page site with minimal indexable text, no metadata, and no secondary content prevents discovery.
The site is visually ~3,500px tall but contains almost no crawlable body text — only a headline, subtitle, and four stat labels. Googlebot sees this as a thin, low-value page. No meta description, Open Graph tags, or schema.org markup exist, so social shares and search results display generic previews. The domain is a single page with no secondary content (docs, blog, tutorials, comparison pages), making it impossible to rank for long-tail keywords that drive qualified traffic.
The "emuko" brand name is not a natural search term. Users searching for solutions to this problem use queries like "RISC-V emulator for macOS," "boot Linux on ARM Mac," or "QEMU alternative in Rust." Without secondary pages and body text targeting these phrases, the site will never appear in those results.
Issue 01 of 03
Almost no crawlable body text for search engines to index
The page is visually ~3,500px tall but contains only a headline, subtitle, and four stat labels of indexable text. The bottom two-thirds renders as empty space that Googlebot will read as a thin, low-value page. Content that exists in the DOM but is hidden via CSS/JS may also be ignored or devalued by crawlers.
Insert a "How it Works" or "Why emuko" section with 300+ words of clear, keyword-rich prose. Cover the problem (RISC-V emulation is slow or unsupported on macOS), the solution (near-native speed via JIT), and differentiators (Rust implementation, minimal dependencies). Ensure content renders without JavaScript.
Issue 02 of 03
No meta description, Open Graph tags, or structured data
Meta descriptions are the first thing searchers read in results. Open Graph and Twitter Card tags control how the link looks when shared — critical for a tool that lives or dies by developer word-of-mouth. Without these, social shares produce a generic preview with no image, no description, and no reason to click.
Add to the <head>: a meta description (160 chars including "RISC-V emulator"), og:title, og:description, og:image, and twitter:card tags. Add a <script type="application/ld+json"> block with SoftwareApplication schema including name, description, url, and applicationCategory.
Issue 03 of 03
The entire domain is a single page with no secondary content
A single-page site has no path to organic growth. Users searching for "How to boot Linux on ARM Mac," "QEMU vs emuko," or "RISC-V emulator benchmarks" will never find this site because no page addresses those queries.
Create at least 3-5 secondary pages: a "Getting Started" guide, a "Features" breakdown, a "Comparison" page (emuko vs QEMU vs native tools), and a "FAQ" or "Docs" section. Each page should target a specific keyword cluster and include 400+ words of unique, authoritative content.
AccessibilityFail 22/100
The site is designed for one user: a sighted developer with a high-end display in a dark room.
The bottom two-thirds of the page is a near-black void with invisible content. Contrast ratios throughout are critically low — body text, navigation links, and UI elements use medium gray on near-black, failing WCAG AA standards. Visual hierarchy depends entirely on a single green accent color with no secondary cues: no underlines, no bold weights, no icons. The "Quick Start" outline button is nearly invisible to anyone without full color perception. Keyboard users find no skip-navigation link and no visible focus indicators. Screen reader users encounter a terminal demo with no alt text or ARIA context.
This is not a minor oversight. It excludes users with low vision, color blindness, motor disabilities, and cognitive differences. On a budget display or in sunlight, the site becomes unreadable. For the ~8% of men with color vision deficiency, green and gray are indistinguishable.
Issue 01 of 03
Text contrast fails WCAG AA across all secondary elements
Body text, subtitles, stat labels, navigation links, and footer all use medium-to-light gray on near-black backgrounds. Measured contrast ratios fall below the 4.5:1 minimum for WCAG AA. On budget displays or in bright environments, this text vanishes entirely.
Raise all secondary text to #e0e0e0 or #f0f0f0 (contrast 15:1+). Use the APCA contrast calculator to audit every text color. Apply the same standard to buttons, links, and labels. Test in a bright room and on a mid-range display.
Issue 02 of 03
Green is the only visual hierarchy signal with no redundant cues
Headlines, stat numbers, CTA buttons, and the version badge all use the same green accent with zero redundant cues. For ~8% of men with red-green color blindness, these elements collapse into uniform gray. There is no secondary visual language: no bold weights, no underlines, no icons, no spacing hierarchy.
Add secondary cues to all emphasized elements. Headlines: increase font weight (700+). Stat numbers: bold + size increase. Buttons: add a border or icon in addition to color. Links: add underlines on hover and focus. Test the design in grayscale to confirm hierarchy remains clear without color.
Issue 03 of 03
No keyboard accessibility infrastructure exists
The page has no skip-navigation link. Focus indicators — if present — are invisible on the dark background. The terminal demo is presented with no alt text or ARIA labels; a screen reader user hears nothing or raw shell output with no context. Tab order is not managed.
Add a skip-to-content link in the header (visually hidden, visible on focus). Add visible focus indicators: 2-4px outline in white or accent color with 2px offset. Use semantic HTML: <nav>, <main>, <button>, <a>. Add descriptive alt text to the terminal demo. Test with keyboard only and a screen reader (VoiceOver on Mac, NVDA on Windows).

A technical deep-dive that leaves mainstream users behind within seconds.
Persona: Average American — 35, moderate income, casual browser, not technical · Viewport: 1280 px
Our typical user scrolls through the emuko.dev homepage and encounters an increasingly disorienting experience: from professional-looking but opaque developer content, to a terminal demo they can't parse, to what feels like a broken website.
Screen 01 of 05
A dark, sleek page greets them with the headline "RISC-V emulation at near native speed" in large text. There's a "View on GitHub" button and a "Quick Start" button. A terminal window is peeking in at the bottom of the viewport. Everything looks polished and professional.
But "RISC-V emulation" might as well be Sanskrit. They don't know what RISC-V is, why they'd want to emulate it, or what "near native speed" means. It's like walking into a store that sells specialized medical equipment — everything is shiny but none of it is for them.
Interest
2/10 — Professional presentation can't overcome complete lack of context
Screen 02 of 05
Now they see a terminal window showing Linux booting up with technical output scrolling. Below it is a stats row: "RV64", "2 JIT backends", "1 External dependency", "~15K Lines of pure Rust". The bottom half of the screen is empty dark space.
This feels like they've walked into a conversation between two engineers at a party and they're just nodding along, pretending to understand. What's a JIT backend? Why should they care about lines of Rust?
Interest
2/10 — Live demo showcases technical prowess, not actual value
Screen 03 of 05
A giant black screen. Essentially nothing visible. Just darkness filling their viewport.
They squint at their monitor wondering if something didn't load right. Did the browser crash? Is the page broken? They're not going to stick around to find out. Nobody scrolls through what looks like a broken page.
Interest
1/10 — Appears broken or unfinished, kills engagement immediately
Screen 04 of 05
Still mostly black, maybe with a faint line or barely visible element. The page continues to be essentially empty.
"Something broke," they think. This is a complete dead end — no content, no explanation, no reason to keep scrolling. At this point they're heading back to Google.
Interest
1/10 — Continued void with zero content to engage with
Screen 05 of 05
A tiny footer appears at the bottom after scrolling through what feels like an endless void: "emuko (c) 2025 Wojciech Adam Koszek. Apache 2.0." on the left, "emuko.dev" on the right. A copyright notice and license after screens of nothing.
An anticlimactic ending with no call-to-action, no summary of what the project actually is, no reason they scrolled this far. They close the tab.

A confusing descent from polished landing to complete darkness with no guidance or call to action.
Persona: Average American — 35, casual phone browser, not technical · Viewport: 390 px (iPhone)
Scrolling through emuko.dev on mobile reveals a sharp disconnect: the top feels intentional and designed, but most of the page is an impenetrable black void with no content, no explanation, and no reason to stay.
Screen 01 of 07
A clean dark page greets with the "emuko" logo, a GitHub button, and a v0.1.0 badge. Bold white text declares "RISC-V emulation at near native speed" with a bright green highlight. Below, a subtitle mentions Rust and JIT compilation, flanked by two action buttons. At the bottom, a terminal window hints at something technical.
"Well-designed for the people it's meant for, but I am definitely not one of those people."
Interest
2/10 — Polished but impenetrable jargon
Screen 02 of 07
A terminal window appears with bright green text showing Linux booting up. Below it sits a stats row: "RV64", "2 JIT backends", "1 External dependency", "~15K Lines". The visual is slick but completely opaque to anyone without deep technical knowledge.
"Feels like I walked into a conversation I wasn't invited to." Dark emptiness below suggests more content, but something feels off.
Interest
2/10 — More mystery, no clarity
Screen 03 of 07
Absolute darkness. Nothing but black from edge to edge. Not a hint of content, text, or structure. Just void.
"Honestly thought my phone froze or the page didn't load." Tapped the screen thinking it was buffering or waiting for something to appear. Total dead end.
Interest
1/10 — Is the page broken?
Screen 04 of 07
Still solid black. No change, no content, no indication that anything should be here. The page is functionally invisible.
"Did the site break? Is my phone glitching out?" At this point, seriously considering closing the browser.
Interest
1/10 — Why am I still scrolling?
Screen 05 of 07
More nothingness. Just endless black space. No visual hooks, no progress indicators, nothing to suggest there's content worth waiting for.
"First thought is the page didn't load right." Checked brightness. "Is this some kind of artsy developer thing?" Starting to feel like the experience is intentionally cryptic.
Interest
1/10 — Complete loss of engagement
Screen 06 of 07
Faint lines barely visible against the black. Almost nothing to see, almost nothing to interact with. The page continues to feel broken or intentionally hostile.
"I'm tapping my screen thinking maybe something's supposed to pop up." Nothing happens. No feedback, no response, just more waiting.
Interest
1/10 — Debugging feels like the goal
Screen 07 of 07
A footer finally emerges from the darkness. Tiny gray text reads: "emuko (c) 2025 Wojciech Adam Koszek. Apache 2.0." and an "emuko.dev" link. The page ends as abruptly as it began, with no landing page summary, no next steps, no reason to engage.
"The page just fizzled out with zero call to action." Scrolled through six screens of emptiness only to find copyright text at the bottom.
