Understand

A 30-second read on any page or app screen.

Open any page, click Quick Scan. EPIC reloads it with capture on, reads what people, AI, browsers and search engines see, and explains it in plain English.

One overall health score plus AI visibility, business clarity, trust, SEO, security, performance, accessibility and privacy
Launch readiness, quick wins and top priorities ranked by impact and effort
“For you” shortcuts that match your role: marketing, developer, security, manager
Optional passive checks badge problems on pages as you browse, with no scan and nothing sent anywhere

Free

Journeys

Does the thing customers actually do still work?

Record a contact form, sign-up or checkout once. EPIC walks it again, by hand or on a schedule, and tells you when it breaks or changes.

Passed, Passed with changes or Broken, with the failing step, what EPIC looked for and a screenshot
Detects new or required fields, renamed buttons and links, new pages in the flow, address changes, JavaScript errors and visual changes
Forms are filled in and validated, never sent; passwords are never stored, and logged-in journeys use your browser's login
Desktop (1280 px) or Mobile (390 × 844), fixed while recording and on every run
Accept intended changes as the new normal; a visual lens to compare any two runs
Free: 1 journey by hand · Observe: 10 scheduled · Modify: 50

Observe + Reporting

Marketing & SEO

Tags, pixels, consent and schema, checked every scan.

See which analytics and ad tags load, whether they fire before a consent choice, and whether your social previews and structured data are right.

Recognises GA4, GTM, Google Ads, Meta, LinkedIn, TikTok, Hotjar, Clarity, HubSpot and more
Reads the consent manager and Google consent mode, and flags tags that fire before consent or after refusal
Large-card, X and chat previews, with fixes for missing or broken share images
Links and UTMs, broken-link check, and a schema validator for 22 schema.org types

Observe + Reporting

Site Scan

Scan the whole site. Fix what matters most.

Crawl up to 100 pages from the sitemap or by following links, and get issues ranked by severity and how many pages they affect.

About 20 checks per page: titles, descriptions, canonicals, noindex, status codes and more
Redirect health: 301/308 vs 302/307, chains, loops, and internal links still pointing at redirects, with changes logged every scan
Site-wide: duplicate titles and descriptions, sitemap problems, broken internal links and where they're linked from
A site health score with the change since the last run
Download as CSV or copy a summary

Resilience Intelligence

How ready is your site for a traffic spike or a common attack?

One readiness score built only from evidence your browser can see, with the biggest wins first. EPIC never sends attack or load traffic.

Protection: CDN, WAF and bot-protection signals, HTTPS, HSTS, HTTP/3, origin exposure, rate-limit signals
Application exposure: sign-in and session observations, API endpoints, exposed secrets, source maps, CORS, 9 security headers
Traffic efficiency: page transfer, cacheable and compressed files, edge-cache hits, third-party share, large assets
Signals it can't see are left out, not guessed, and tracked over time in the Change Log

Observe + Reporting

Dependencies & Redirects

What changed, who caused it, and why it matters.

Every first- and third-party dependency on the page, what's new since your last scan, and plain-language correlations with page weight and speed.

First party vs third party: requests, transfer, scripts, stylesheets, images, fonts and API calls
110 known services in 20 categories, trackers & ad services, render-blocking and failed third-party files
“Page weight increased 1.2 MB. Most of it came from your own files. Largest new file: carousel.bundle.js.”
Compare with the previous scan or 30, 60 or 90 days ago; how visitors reach the site (http/https, www), hop by hop

Observe + Reporting

Security

HTTP & API security with fixes ready to paste.

Grade security headers, audit cookies and CORS, and find credentials that leaked into client-side code, all from the page your browser already loaded.

Security header grade (A to F) with config for nginx, Apache, IIS, Cloudflare/Netlify and Express
Cookie flags, CORS, and subresource integrity on third-party scripts
18 kinds of exposed secrets (AWS, Stripe, GitHub, OpenAI and more), masked and never stored
Public source maps and a JWT inspector for tokens in URLs, headers, cookies and storage

Observe + Reporting

Quality

Know exactly what changed in every deploy.

Console errors, failed requests and a before-and-after deploy check, so regressions are caught by you, not your users.

Console errors and exceptions with file, line and stack, with EPIC's own activity filtered out
Failed requests split into first-party and third-party, with ad-blocker blocks identified
Save a snapshot, deploy, rescan: regressions and improvements in one list
Copy as a GitHub or Jira issue, or a PR comment

Observe + Reporting

History & monitoring

Know what changed, not just what's wrong.

Every scan is stored on your device and compared with the last. 100+ measurements, every file, every tag and every third party, logged whenever they change.

Change Log: scores that move 2+ points, any change in page size or requests, new/removed/resized files, SEO and content, tags and consent, security headers, errors and speed
Scheduled monitoring for up to 10 sites (25 on Modify), with competitors and baselines
Alerts at the threshold you choose (browser notifications), and a weekly digest
Keep 30, 60 or 90 days (up to a year on Modify), download anytime, or save a weekly CSV automatically

Observe + Reporting

Visual Timeline

A visual history of your site.

A screenshot is saved with every scan of a saved website. Slide through time, or compare any two moments.

Side by side, highlight changes (changed areas marked) or swipe
Compare with the first screenshot or the one before
The same lens powers every journey page
Stored in your browser and cleaned up with the history period you choose
