Multi-Axis Scoring Breakdown (0–100)
Confidence: 100%5 Readiness Gate Checks
Ready for MVP1. Core Problem Statement
Web designers and developers struggle to verify compliance with WCAG 2.1 contrast rules and simulate colorblindness on dynamic single-page applications.
2. Target Segment & ICP
Frontend engineers, UI designers, and digital agency teams building compliant e-commerce and corporate web portals.
5 & 6. Pain Frequency & Severity
Frequency: daily · Severity: 8/10
7. Current Solution & Workarounds
Heavy enterprise platforms like Stark ($15/mo) or obsolete free extensions that break on modern SPAs.
9. Competitor Gap & Vulnerability
Legacy extensions don't work on localhost/authenticated pages; enterprise competitors charge recurring seat fees.
10 & 12. Willingness to Pay & Monetization
Developers eagerly pay a clean $10–$19 one-off fee to avoid recurring monthly SaaS subscriptions.
One-time Purchase ($10 Solo / $49 Agency Team License)
11 & Why Now. Market Demand & Why Now
Surging interest driven by the European Accessibility Act (EAA) and ADA compliance legal scrutiny.
Mandatory EU/US digital accessibility regulations create urgent legal demand for compliance auditing tools.
13. MVP Scope (2–6 Weeks Solo Build)
MV3 extension with hardware-accelerated SVG filter matrix (protanopia, deuteranopia, tritanopia, achromatopsia) + contrast picker.
Build Time: 2–3 weeks
Regional Market Context & Adaptation
Optimize for Chrome Web Store search keywords: 'colorblind simulator', 'wcag contrast checker', 'accessibility audit tool'.
Verified Demand Evidence Layer
Independent Evidence Groups: 3Strong sustained user demand for modern, reliable color vision deficiency simulators directly in the browser.
“Popular legacy colorblind simulators have 200,000+ active installs but have not been updated since 2021. Users report broken SVG filters on dynamic React/Tailwind SPAs and lack of WCAG AA/AAA compliance scoring.”Chrome Web Store Accessibility Extension Reviews
Legislative pressure (European Accessibility Act & US ADA) forces agencies and developers to audit color contrast.
“With the European Accessibility Act taking effect, our agency needs every frontend developer to audit contrast and 4 types of colorblindness. Enterprise suites like Stark cost $15/seat/month which is overkill.”r/webdev
Verified corporate willingness to pay for rapid accessibility and color vision audit reports.
“Freelance contracts paying $200–$500 per audit to inspect e-commerce websites for protanopia, deuteranopia and low-contrast UI elements.”Upwork WCAG Accessibility Audit Jobs
Competitive Landscape (1–5 Alternatives)
| Competitor | Type | Pricing | Est. Revenue | Strength | Weakness & Attack Angle |
|---|---|---|---|---|---|
| Stark | direct | $15/mo | $60,000+ | 70/100 |
Expensive monthly subscription per seat; feature bloat for solo devs who just need quick browser simulation. → Lightweight, zero-account browser extension with instant $10 lifetime payment and 1-click WCAG contrast export. |
| Toptal Colorblind Web Page Filter | indirect | $0/mo | $0+ | 57/100 |
Requires pasting URL into external proxy; fails on authenticated local dev servers (localhost). → Works locally on localhost:3000, Figma preview tabs, and authenticated staging environments. |
