What is Browserling?
Browserling is an online cross-browser testing platform that enables developers and quality assurance teams to validate web applications across multiple browser environments. By running real desktop browsers on virtual machines, it eliminates the need for physical device testing and provides immediate access to the latest browser versions. The tool is primarily used by frontend developers, QA engineers, and product managers to identify compatibility issues, ensure responsive design, and verify security vulnerabilities. It addresses the challenge of ensuring consistent user experiences across diverse browser ecosystems, particularly when dealing with legacy browser support or emerging web standards. Browserling's core value lies in its ability to simulate real-world browsing conditions without requiring local installations. Users can interact with live browser sessions, capture screenshots, and perform responsive testing to ensure websites function correctly across varying screen sizes. The platform also includes a cybersecurity sandbox for testing potential vulnerabilities, making it a versatile tool for both development and security workflows. Its real-time capabilities and support for major browsers like Chrome, Firefox, and Internet Explorer make it a practical solution for teams needing rapid cross-browser validation.
How it works
Browserling is a web-based tool that provides remote access to real browsers running on virtual machines. It allows users to test websites in environments that mirror actual user setups, ensuring compatibility across different operating systems and browser versions. The primary purpose of Browserling is to streamline cross-browser testing by eliminating the need for local browser installations. Developers can quickly identify layout issues, script errors, or rendering discrepancies without configuring multiple local environments. Browserling supports real browsers including Chrome (versions 34–114), Firefox (32–114), Internet Explorer (7–11), and Opera (39–94). Users can interact with live sessions, resize browser windows, and capture annotated screenshots for bug reporting. The platform also includes a cybersecurity sandbox for testing malicious code interactions.
How to use it
- 1Visit browserling.com and create an account. 2. Select a browser version and operating system from the available options. 3. Load your website URL into the live session. 4. Interact with the page, resize the browser window, or capture screenshots. 5. Use SSH tunnels to connect local servers for advanced testing scenarios. Practical tips: Use the screenshot annotation tool to highlight issues. For local testing, configure SSH tunnels via the terminal to forward traffic from your development server to Browserling's infrastructure.

Frequently asked
What browsers does Browserling support?
Browserling runs real desktop browsers including Google Chrome (versions 34–114), Mozilla Firefox (32–114), Microsoft Internet Explorer (7–11), and Opera (39–94). These browsers operate on virtual machines, ensuring accurate rendering and behavior without local installations.
How does Browserling handle local server testing?
Browserling provides SSH tunneling capabilities to forward local development servers to its infrastructure. Users can establish reverse SSH connections via the terminal, allowing them to test backend services or local files as if they were hosted on the platform's servers.
How do I capture and share screenshots?
During a live session, click the screenshot button to capture the current browser view. Save the image locally or share it directly via email. The tool also allows annotation of screenshots with text and arrows to highlight specific issues or bugs.
How does Browserling compare to BrowserStack?
Browserling and BrowserStack both offer cross-browser testing, but Browserling focuses on real browser environments without local setup, while BrowserStack provides more extensive browser version coverage and CI/CD integrations. Browserling's SSH tunneling is ideal for local server testing, whereas BrowserStack emphasizes cloud-based testing for enterprise workflows.
What should I do if my test session disconnects?
Session disconnections may occur due to server load or network instability. Refresh the Browserling interface to reconnect to an available virtual machine. For persistent issues, check your internet connection or contact support for troubleshooting.
