Why teams pick TestingBot for live browser testing

Real, never emulated

Every session runs on a real macOS, Windows or Linux VM with the real browser binary. No headless shims, no fake Internet Explorer. The DOM, the JS engine and the cipher suite are exactly what your customer sees.

From IE 8 to the latest beta

Chrome, Safari, Firefox, Edge, Opera and every Internet Explorer back to IE 8. macOS Tahoe through Yosemite, Windows 11 through Windows 7, and Linux. The full matrix, always patched.

Zero install, zero setup

No browser extensions, no Java applet, no agent on your machine. Click a browser, our cloud streams a live, interactive desktop into the tab you already have open.

Capabilities

Everything a real browser session gives you

A live cross-browser test should feel like sitting at the customer's machine. Native dev tools, real input, real audio, real network conditions.

  • Native DevTools

    Open the same DevTools your developers use locally. Chrome DevTools, Safari Web Inspector, Firefox DevTools and the F12 tools in Edge and IE, fully interactive over the live stream.

  • Streamed audio

    Hear video playback, autoplay policies, Web Audio output and HTML5 media events the way the customer would. Audio streams from the remote VM straight into your tab.

  • Real keyboard and mouse

    Type, scroll, drag, right-click and use modifier keys. The remote browser sees the same input events as a local one, so hover menus and keyboard traps behave normally.

  • Two-way clipboard

    Paste credentials, JSON fixtures or long URLs from your machine into the remote browser. No plugin to install. Copy data back out the same way.

  • Any resolution, on the fly

    Switch between 1280x720, 1920x1080, 4K and custom resolutions mid-session to validate responsive breakpoints without restarting the browser.

  • Geolocation testing

    Run a session that exits from the United States, the EU, the UK, Australia, Japan or other regions. Validate currency, language detection, GDPR banners and CDN behaviour.

  • Network throttling

    Simulate Edge, 2G, 3G, 4G and offline conditions. Catch perceived-performance bugs before they hit users on a train or in an elevator.

  • Mobile browsers

    Live sessions on real iPhones, iPads and Android phones from Samsung, Google, Xiaomi and OnePlus. Mobile Safari, Chrome on Android, Samsung Internet, no emulator in sight.

  • Screenshots & video

    Every session records a full video and lets you snap, annotate and share screenshots in two clicks. Send bugs straight to Jira, Slack or GitHub.

  • Beta and dev builds

    Reproduce bugs on Chrome Beta, Firefox Nightly, Safari Technology Preview and Edge Dev within hours of upstream release.

Browser and OS coverage

Real browsers vs. local VMs

Why developers stop running their own browser farm

Maintaining your own VirtualBox image of IE 11 on Windows 7 was already painful in 2018. Here is what teams get back when they move to TestingBot.

Real browsers on real macOS, Windows and Linux

TestingBot does not ship a custom-patched Chrome or a "Chromium-based" Safari clone. Every browser runs on the real operating system it shipped for, with the real binary from Apple, Microsoft, Mozilla and Google. The CSS engine, the JS engine, the TLS stack, even font rendering match what your customer sees.

  • Real Chrome on real macOS, not Chromium on Linux
  • Real Safari on real macOS Tahoe through Yosemite
  • Real Internet Explorer 8, 9, 10 and 11 on the right Windows release

Real iPhones, iPads and Android phones from the same tab

Switch from a desktop Chrome session to a real iPhone running Mobile Safari, or a real Galaxy running Chrome on Android, without changing tools. Tap, scroll, pinch-zoom, rotate, and inspect the page with the real device's Safari Web Inspector or Chrome DevTools.

Network throttling sits alongside geolocation: simulate Edge, 2G, 3G, 4G or offline in the same session.

Geolocation testing

Test from where your customers actually are

Route a live session through an exit node in the United States, the UK, Germany, France, Japan, Australia or other regions. Validate currency, language detection, ad bidding, GDPR consent flows and edge CDN behaviour without flying anywhere.

Secure tunnel

Test staging and internal apps behind your firewall

TestingBot Tunnel opens a secure, encrypted route from our cloud browsers to your local server, staging environment or internal network. No VPN, no firewall changes, full control of the proxy and policies.

Start the tunnel from your laptop or your CI runner. The session loads your staging URL exactly the way the user will see it in production, with cookies, auth and SSO intact.

Security

Pristine VMs, wiped after every session

Each live test gets its own isolated virtual machine. We do not share state between customers. The instant you close the session, the disk is destroyed and the next test starts on a clean image.

TestingBot is SOC 2 aligned, GDPR compliant, and supports SAML SSO on enterprise plans.

  • One customer per VM, never co-tenanted
  • Datacenter-hosted, not residential proxies
  • Disk and memory wiped at session end

From any OS

Need Safari from Windows? IE from a Mac? Just open a tab.

Designers on Macs need to check Internet Explorer. Windows devs need to check Safari. Linux engineers need to check Edge. TestingBot gives every machine in your company access to every browser, without anyone installing a VM.

The browser runs in our datacenter. You interact with it through a normal browser tab using HTML5. There is nothing to download.

Collaboration

Report bugs without leaving the session

Take and annotate screenshots, share the live session with a co-worker, and download the automatic video recording when the test ends. Each bug ships with the metadata an engineer actually needs: browser, OS, screen size, network conditions and console output.

FAQ

Frequently Asked Questions

Do I need to install anything?

No. Live browser sessions run entirely in your existing browser tab using HTML5. There is no agent, no Java applet, no browser extension and no Flash. Sign in, click a browser, and the live desktop streams straight into the tab.

Can I hear audio from the remote browser?

Yes. Audio from the remote VM is streamed over the same WebRTC connection as the video, so video playback, autoplay policies, Web Audio output and media events behave the way they do on a customer's machine.

Can I change the screen resolution mid-test?

Yes. Switch between common breakpoints (mobile, tablet, laptop, 1080p, 4K) or set a custom resolution at any point in the session. The remote browser resizes without restarting, so responsive design work does not lose context.

Which browser versions are available?

TestingBot covers Chrome, Safari, Firefox, Edge, Opera and Internet Explorer 8, 9, 10 and 11 across macOS Yosemite through Tahoe, Windows 7 through 11, and Linux. New stable releases land within hours of upstream availability. Beta, Dev and Nightly channels are available on request.

Do I get the native developer tools?

Yes. Chrome DevTools, Safari Web Inspector, Firefox DevTools and the F12 tools in Edge and IE are fully interactive over the live stream. You inspect, profile, edit and debug exactly the way you do locally.

Can I test a site running on my laptop or staging?

Yes. Start TestingBot Tunnel on your machine or in CI. The cloud browsers see your localhost, staging URL or internal-network site over an encrypted route, with no VPN or firewall change required.

Does TestingBot record the session?

Yes. Every live session is recorded as a downloadable video, plus screenshots, console logs and network HARs. Sharing a bug is one link, not a re-run.

Is my data safe?

Each session uses its own isolated VM that is destroyed after you disconnect. TestingBot is SOC 2 aligned and GDPR compliant. Enterprise plans add SAML SSO and dedicated infrastructure.

Do I need a credit card to try it?

No. The free trial does not require a credit card. Sign up with an email address and you can start a live browser session immediately.
