Console for mobile browsers

Share

Open-source mobile web console that embeds a full developer toolkit into any mobile browser. Provides console, element inspection, network monitor, resource viewer, performance timing, and JavaScript execution on devices that lack native DevTools. The de facto standard for debugging responsive layouts, mobile-specific JavaScript errors, and production issues on phones — loaded with a single script tag or a browser extension.

Eruda by liriliri is an embeddable mobile web console that gives developers a full DevTools experience inside any mobile browser. Traditional Chrome DevTools require USB tethering and the desktop browser; Eruda instead ships as a JavaScript library you include on the page, exposing a floating button that opens a panel UI. The panel mirrors the layout and features of desktop DevTools so teams can inspect production issues directly on a phone without special tooling.

The console supports logs, warnings, errors, and arbitrary JavaScript execution. The Elements tab shows the live DOM with attributes, inline styles, computed styles and CSS rule inspection. The Network monitor records XHR/fetch requests with headers, payloads and response bodies. Additional built-in plugins cover page FPS and memory monitoring, feature detection, performance timing and benchmarks. Everything is keyboard-navigable and theme-switchable, so it works equally well on iOS Safari, Android Chrome and embedded WebViews.

Eruda is distributed on npm and GitHub with 18K+ stars and is also packaged as Firefox Android and Chrome extensions through the liriliri ecosystem. It is the tool of choice for QA engineers, frontend developers debugging responsive layouts and anyone shipping mobile-first web apps who cannot rely on remote debugging — drop in the script during troubleshooting and remove it when done.

Webwright

Microsoft browser agent that turns long-horizon web tasks into reusable Playwright code

Webwright is a Microsoft browser-agent project that asks coding models to write, debug, and reuse Playwright scripts instead of relying on one-off stochastic click loops. The approach gives automation teams a more inspectable artifact: scripts can be logged, reviewed, rerun, and maintained like normal test or scraping code. It is especially relevant for long-horizon browser tasks where teams care about determinism, auditability, and resilience to UI changes.
