I built a tool that runs a full UX + accessibility audit on any URL in under 5 minutes

I've been doing UX audits manually for years — heuristic evaluations, WCAG checks, writing up findings. It takes hours per site. So I built Parallax to automate the whole thing.

How it works:

Paste any URL
It crawls up to 25 pages
You get a scored report covering Nielsen's 10 usability heuristics + WCAG 2.1 AA accessibility checks — 25+ criteria per page
Each finding includes severity, what's wrong, and how to fix it.

Free tier: 1 audit/month with summary scores and category breakdowns.

I'd love feedback — what would make this more useful for your workflow?

How We Built an Autonomous UX Auditing Agent

We recently shipped Parallax — an AI agent that automatically audits UX quality. Here's how it works and the challenges we solved.

The Problem

Traditional UX testing requires:

Hiring UX researchers ($80-150K/year)
Running quarterly research cycles (2-3 months)
Manual heuristic evaluation against Nielsen's 10 usability principles
Accessibility scanning (WCAG compliance)
Generating reports and prioritizing fixes

Result: Most companies do UX audits 2-4x/year. Problems discovered in Q2 don't get fixed until Q3.

The Solution: Autonomous Auditing

1. Crawling Smart User Paths

Instead of crawling every page, we identify critical flows:

Sign-up → Payment
Search → Product detail → Checkout
Login → Dashboard → Action

Each flow gets scored individually, so you see where users actually struggle.

2. Heuristic Evaluation

We implemented Nielsen's 10 Usability Heuristics as a scoring framework:

Visibility of system status
Match between system and real world
User control & freedom
Error prevention
Error recovery
Flexibility & efficiency
Aesthetics & minimalism
Recognition vs. recall
Documentation
Recovery from errors

Each is scored 0-100 based on page structure, copy clarity, interaction patterns.

3. Accessibility Scanning

WCAG 2.1 AA compliance checking:

Color contrast ratios
Heading hierarchy
Form labels & descriptions
Keyboard navigation
Focus indicators
Image alt text

4. Smart Prioritization

Not all issues are equal. We weight by:

Impact (how many users affected?)
Effort (how hard to fix?)
Criticality (does it block core flows?)

Why This Matters

Speed: Audit cycles go from weeks to minutes
Frequency: Catch regressions before they hit production
Scale: Run across 50+ competitor sites to benchmark
Cost: No hiring UX researchers for routine audits
