In-Browser DevTools & Website Inspector

Load any website in a sandboxed frame and inspect it with mobile developer tools powered by Eruda — console, network and element inspection.

How to use the in-browser DevTools

Enter the address of a page and it loads inside a sandboxed frame with a mobile developer console attached, powered by Eruda. From there you can open the console, inspect elements, watch network activity and read logs — the same kinds of insight a desktop browser's developer tools give you, but usable on a phone or tablet.

It is aimed at quick inspection: load a page, poke at it, and see what it is doing under the hood.

Why inspect pages this way?

Mobile browsers usually hide developer tools, so debugging how a site behaves on a real phone is awkward. An on-screen console you can summon inside the page closes that gap, letting you check console errors, inspect the DOM and observe requests directly on the device where the problem appears.

It is also useful for a fast look at a page's structure or behaviour without opening a full desktop toolchain.

How it works

The target page is loaded in a sandboxed frame and the Eruda developer-tools library is injected alongside it, providing the console, elements, network and other panels as an overlay. Everything runs in your browser session. Some sites set headers that prevent being framed by another page, so not every URL can be loaded this way — that is a security choice by those sites, not a fault of the tool.

No page you inspect is proxied through or stored on a server.

Frequently asked questions

Why won't some websites load?

Many sites send headers (like X-Frame-Options) that stop them being embedded in a frame, so they cannot be inspected this way.

What is Eruda?

Eruda is an open-source mobile console that provides console, element and network panels as an overlay inside a page.

Does this work on mobile?

Yes. That is its main purpose — bringing developer-tools-style inspection to phones and tablets that normally hide them.

Is the inspected page sent to a server?

No. The page loads in your browser and the tooling is injected client-side.
