console.mobi: DevTools Browser

Debug & security-check websites on your phone: console, DOM, network, storage

console.mobi is a mobile browser with built-in developer tools (DevTools) that lets you inspect, debug and security-check websites right on your phone.

Inspect element, browse the live HTML DOM and use a web inspector on any website, right from your phone.

Just like desktop DevTools: capture console.log output, inspect the DOM, monitor network requests, view cookies and LocalStorage, and even run JavaScript — all on a real mobile device. Perfect for hunting down bugs that only happen on mobile.

■ Security (NEW) — leak-risk check
- Open a page and console.mobi automatically checks it for common leak risks
- Secrets in LocalStorage / SessionStorage (e.g. AWS, Stripe and GitHub keys, JWTs)
- NEW: secret keys hidden in the page's own JavaScript and source maps (AI, payment and Supabase keys), vulnerable libraries, exposed source maps and third-party scripts without integrity (SRI)
- Cookie flags (HttpOnly, Secure, SameSite)
- Network leaks (credentials over plain http, tokens in URLs, mixed content)
- Security headers (CSP, HSTS, X-Frame-Options and more)
- Runs on your device — captured data is never sent to our servers
- See the number of findings for free; locations and how to fix them with Pro
