SCAN
Score any site in minutes.
Point PlayHero at any URL. Seven pillars scored in parallel — no account, no snippet, results before you've signed up.
THE SYSTEM
From free scan to always-on monitoring.
RALLYCARD
Findings priced, not just flagged.
Each finding ships as a governed decision artifact: verb-first title, disclosed method, and a benchmark-based pipeline figure.
HEROBOARD
One board. Every approved fix.
Approved Rallycards land on a single prioritized board — institutional memory for every UX decision your team makes.
MONITORING
Always on. Never autonomous.
Specialist agents watch every monitored page. Detection is continuous. Execution always waits for a human.
01Scan Pipeline
Four detection layers. One URL. 60 seconds.
Every scan runs four passes in parallel: structured DOM analysis, rule-based threshold checking, Lighthouse performance measurement, and LLM qualitative interpretation. Click each stage to see exactly what it detects and how it contributes to finding confidence.

Stage 01 / 4
DOM Fetch
PlayHero fetches the full rendered DOM of the target URL across three viewport widths: 375px (mobile), 768px (tablet), 1440px (desktop). This is not an HTTP request — we render the page in a headless browser to capture the post-JavaScript DOM, exactly as a visitor would see it.

Confidence basis
Objective. DOM position is a fact. CTA above-fold at 375px is measurable.
02Rallycard Anatomy
Every field exists for a reason.
A Rallycard is a governed decision artifact — not a notification. Every field is designed to give the human reviewer exactly what they need to make a confident decision. Hover each field to see why it's there.

Card immutability
Once a card is approved, the original finding is locked. Status changes (In Progress, Resolved) are appended as a log — the original card is never overwritten. This is how the Heroboard becomes institutional memory, not just a task list.
036 Pillars
Six scored dimensions. Specific thresholds. No guesswork.
The WebUX Score is not a proprietary black-box metric. It is the weighted composite of seven pillar scores, each measured against published or well-established thresholds. Click any pillar to see the exact thresholds used and why they were chosen.
04Four Agents
Four specialists. Defined domains. No overlap.
Each agent has a stable identity, a specific detection domain, and a confidence methodology suited to its signal type. Domain isolation is deliberate — a UX finding from UX Sentinel and a CWV finding from Page Vitals Enforcer are detected by fundamentally different methods, and conflating them would lower the credibility of both.
UX Sentinel | Drift Detector | Page Vitals Enforcer | Lumen | |
|---|---|---|---|---|
| Domain | Conversion friction & technical UX | WebUX signal drift & page anomalies | Core Web Vitals & performance | AI discoverability & agent readiness |
| Detection method | DOM analysis + LLM + rule-based | Page signal monitoring + trend analysis | Lighthouse + script enumeration | Structured data + llms.txt + content extraction |
| Confidence threshold | DOM evidence + LLM agreement | Statistical significance vs. 30-day baseline | Objective threshold breach | Deterministic signal presence |
All four agents run in parallel on every monitoring cycle. A single URL check produces outputs from all active agents simultaneously — findings are not sequential.
Full agent specifications →05 Heroboard
Governance layer. Institutional memory.
The Heroboard is not a task manager. It is the permanent, searchable record of every UX decision your team has made against your monitored pages. Every card that passes through it — approved, dismissed, or deferred — creates a log entry that cannot be deleted.

Card lifecycle states
Card has been surfaced by an agent and is waiting for a human decision. The agent continues monitoring while the card waits — additional evidence may update the finding.
Permanent record
Every decision — approve, dismiss, defer — is logged with actor identity and timestamp. Deletions are not permitted. Over time, the Heroboard becomes the only complete history of every UX decision that touched your pipeline.
06Script Audit + Competitor Mode
Script audit and competitor mode. Both free. No account.
Script audit runs on every scan automatically — no configuration needed. Competitor observation mode activates automatically when you scan a URL you don't own, suppressing pipeline estimates that would be speculative.
Script Audit
Every third-party script, sized and risk-rated.
Included free on every scan. PlayHero enumerates all third-party scripts loaded on the page, identifies them by origin, sizes them by transfer weight, and risk-rates them based on their contribution to LCP and Total Blocking Time.
Analytics scripts
GTM, GA4, Segment, Heap — load weight + LCP contribution
Support widgets
Intercom, Drift, Zendesk — often the largest TBT contributors
Unknown origins
Scripts with no identifiable owner flagged as high risk
Optimization suggestions
Linked to Page Vitals Enforcer findings where relevant
Script audit is included with every free scan. No account required.
Competitor Observation Mode
Scan any URL. Pipeline estimates removed automatically.
When you scan a URL you don't own, PlayHero automatically enters observation mode. The full 7-pillar analysis runs, but pipeline dollar estimates are suppressed — you can't model conversion impact for a site you don't have traffic data for, and fabricating those numbers would undermine the credibility of the findings.
What you get in observation mode
→Full 7-pillar score comparison
→Relative UX positioning vs. your own score
→Qualitative findings (no pipeline $ estimates)
→Script audit and CWV measurements
Legal clarity: Observation mode removes all revenue projections from competitor scans. UX quality is observable. Revenue impact from someone else's site is not.
07Trust Contract
Five things that are non-negotiable.
Every feature we ship is evaluated against these five commitments. They are not marketing copy — they are constraints that have shaped product decisions from day one. The ones that slow us down are the ones that matter most.
01Detection method always disclosed
Every Rallycard shows which technical method detected the finding. DOM structure analysis is objective — a CTA below fold is measurable. LLM interpretation is probabilistic — a value proposition missing ICP clarity is an assessment. Users see the difference on every card.
02Severity is not revenue certainty
Severity is the detecting agent's rating of the issue. It is never shown as a measure of revenue impact certainty. The pipeline impact range is always a benchmark-based estimate, always labeled as such, with methodology disclosed inline — not in a footnote.
03Nothing executes without your approval
No agent moves a card to execution. No change is made to your site. No action is taken on your behalf. Approval is a governance signal — it moves the card to In Progress and notifies your team. Your team executes. Agents track what's running.
04Assumptions are editable after signup
The traffic volume, average deal value, and CVR baseline underlying every pipeline impact estimate are editable post-signup. The default assumptions are disclosed on every card. You can calibrate them to your actual site data, making every subsequent impact estimate more accurate.
05The audit trail is permanent
Every decision — approve, dismiss, defer — is logged with actor identity and timestamp. This record cannot be deleted. Over time, the Heroboard becomes institutional memory: the only complete history of what was found, who decided what, and what changed afterward.
