Observe
Deploy check
Save a snapshot, ship, rescan. Console errors, failed requests, speed and every new or changed file, as one list of regressions and improvements. Copy it as a GitHub or Jira issue.
Observe
Every file, every size
New, removed and grown files between scans, down to 1 KB. Renamed builds such as app.3f9a.js → app.7d2e.js are matched, so you see “app.js grew 240 KB”, not noise.
Modify
Every API on the screen
The HTTP/API Lab lists every call a screen makes: REST, GraphQL, SOAP, OData or WebSocket, with status, timing and how it's authenticated. Replay or edit any request and copy it as cURL, fetch or Python.
Observe
API & session security
CORS that lets other sites read your API, JWT weaknesses, session cookie flags, keys and tokens exposed in client code, public source maps, security headers with fixes.
Observe
Third parties in your app
Every outside service your app loads, recognised across 110 known services, with what's new since the last scan and what it added to page weight.
Free
Works where you're signed in
Quick Scan reloads the tab you're on with your existing session, so it analyses the real app screen, not the login page. Nothing is sent to us.
Modify
Test fixes and flags
Change request and response headers, cookies (feature flags, sessions), HTML, CSS or JavaScript, or block a script, in your own browser only.
Observe
Sign-up and upgrade flows
Record your sign-up or upgrade flow on your marketing site once; EPIC re-checks it on a schedule and never submits the form.
Observe
Ready for a launch spike
A resilience score from caching, CDN, rate-limit and error-handling evidence. Read-only: EPIC never sends load or attack traffic.
