A new user interface for Browserling!

Pinned post

Exciting news at Browserling! My team and I just launched a brand new product interface for Browserling. The new interface lets you access all browsers on all platforms and all features through a single neat menu.

You can try the new user interface right now by following this quick browsing link:


This link will open this same blog post in the latest version of Chrome.

The menu

The new menu contains everything you need to work with Browserling browsers. The top part of the menu focuses on the platform, the browser, and the website that you want to test, and the bottom part lets you quickly access the most popular features.

The features include display options (allows zooming the browser and changing resolutions), screen capture (allows capturing browser screenshots and quickly annotate them), local testing (allows opening an ssh tunnel to localhost or local network to test local websites), on-screen keyboard (allows using an English keyboard on non-English computers, and allows using a keyboard on mobile devices), share a browser (allows sending a quick link to the current browser and website you're viewing), and send feedback (we love feedback!)

Operating system and browser selection

The operating system and browser selection lets you quickly access all available platforms and browsers. With a click or two you quickly load the browser version you need.

URL navigation

The URL navigation field lets you quickly navigate to the website you need. Just enter the address of the website, click the go button, and a browser will open and load the website.

Display options

The display options feature lets you zoom the browser in and out (especially useful if you're on a 4k screen) and change the resolution to a bigger one or a smaller one. Also, this feature lets you do responsive web testing as you can see how your website looks on various screen sizes.

Capture screen

The screen capture feature lets you quickly capture screenshots of your browsing sessions. Once you select the browser region you want to capture, it opens a screenshot of this region and you can use the editing tools, such as a pen, rectangle, text annotation, and eraser tool to make modifications to the screenshot.

I'll be writing another more detailed article about this feature in one of the next posts as it has many other amazing features that let you quickly copy screenshots to clipboard, share bug reports with your co-workers by emailing them, uploading to Imgur, downloading, or saving to your account for later viewing.

Also, coming soon, you'll be able to record your browsing session to a GIF (we call it a GIFcast) or a video.

Local testing

The local testing feature lets you test your local websites that run on the localhost or any local network machine through ssh tunnels. The initial dialog lets you enter the hostname and port of your local web server.

Then, once you run the ssh command and establish a connection between your local computer and our tunneling service, it changes to connected state and you can start testing.

If the connection drops at any time, you'll instantly be notified through a yellow warning message.

I'll be writing another article about local testing as there's a lot to explain.

Onscreen keyboard

The virtual keyboard lets you easily send keypresses to the browser even if you're using a device that doesn't have a physical keyboard, like a tablet. Also, it's very useful if you're using a non-English keyboard, such as German or French keyboards as they have keys for "at" and "slash" symbols in different places.

The keyboard window can be resized to any size, made more compact if you're on a smaller screen or expanded if you're on a bigger screen.

Share a browser

The browser sharing feature lets you quickly share a link to the current platform, browser, and URL that you're viewing with your co-workers and friends.

Also, coming soon, we're launching a collaborative browsing feature that will let you and your team share the same browser.

Send feedback

We love getting feedback, so we also added a quick way to share your thoughts. Let us know what you think about the new UI! My entire team gets all feedback messages.

Technical details

We built our user interface using plain HTML, CSS, JavaScript, and the if statement. We started with an empty text file and finished with a fully working self-contained application that we deployed to production in 0.1 second. There are no frameworks, no dependencies, no node modules, no bundlers, no rust, and no modern web crap. There's just code that runs the user interface that lets us keep our focus 100% on the product and 0% on resolving node module issues.

What's next?

Next, we're launching a new browser streaming algorithm. The new streaming algorithm will offer near-native experience when using remote browsers. Then, we're adding a collaborative browsing feature that lets two or more people use the same browser at the same time. After this, we're adding a screen recorder that lets you capture your browser sessions to gifs and mp4 videos. And then! More awesome things!

What's Browserling?

Browserling is the world's first online cross-browser testing platform. It offers web developers, web testers, and qa teams quick access to all browsers on all platforms. To make really great web apps and websites, you need to make sure your code and design looks and functions the same on as many platforms, browsers, and screen sizes as possible. You could maintain a bunch of virtual machines and devices or you can simply use Browserling that offers quick cloud access to all the browsers.

Browserling's customers include L'Oreal, T-Mobile, Dolby, Accenture, Payoneer, Wegmans, Library of Congress, House of Representatives, City of New York, State of Texas, UK Home Office, and Government of Australia.

What are other common Browserling use-cases?

Besides being a useful cross-browser testing service, Browserling is also used by security professionals to get a sandboxed browser for testing suspicious links and casual Internet users who want to browse the Internet in an online browser without being tracked.

Thanks everyone for following along my adventure and see you all next time!

If you build it, they will come

TLDR: We built it and they came.

At Browserling, over the last couple of years we built a network of online tools websites. Each website focuses on one category of tools and each tool does one and only one thing. We made all tools free, without ads, and with the simplest possible interface that uses a <textarea> or a <canvas> for the user input and output. We let Google decide the fate of the project and it was a huge success – people loved our free tools, sent us backlink love, we started ranking at the top, and now, all tools are used by millions of people every month. All tools followed the same growth curve – it took on average 2 to 3 years for each site in the network to became popular. The success formula was very simple: building things that people search for + patience = success. Now that we have captured the market, we're merging all these sites into a single ultimate get things done site OnlineTools.com and adding paid plans to make it a huge financial success.

Update: Executed.

Here's what we built.

We built Image tools and they came:

We built Hex tools and they came:

We built Ascii tools and they came:

We built Gif tools and they came:

We built String tools and they came:

We built Number tools and they came:

We built JSON tools and they came:

We built XML tools and they came:

We built YAML tools and they came:

We built Unicode tools and they came:

Build too and see you next time! Just remember – if you don't build it, they won't come.

How to Access the Tor Network Without Installing the Tor Browser

TLDR: You can use Browserling and get an online Tor browser via browserling.com/tor.


Anonymity and privacy on the Internet have never been more critical. The Tor browser, renowned for its robust privacy features, has long been the go-to option for anonymous browsing. However, not everyone wants to download and install additional software (especially Tor) or might be using a computer where installations are restricted. At Browserling, we created a cloud version of the Tor browser and you can start browsing Onion links directly from your standard web browser. This blog post delves into how you can use an online Tor browser via Browserling without any installations.

What Sets the Tor Browser Apart

The Tor browser is a specialized web browser built for anonymity and privacy. It achieves this by routing your web traffic through a network of relay servers, effectively masking your identity and location. Tor, which stands for The Onion Router, encrypts your data in multiple layers, similar to an onion, providing a robust level of security. While the Tor network is what provides this routing capability, the Tor browser is the application that enables easy access to this network for general users.

Foundation on Firefox

At its core, the Tor Browser is built on the Firefox browser. This means that the user interface and many functionalities are similar to those you'd find in Firefox. However, the Tor team has extensively customized this foundation to integrate the Tor protocol and add a myriad of privacy-focused features.

Key Differences from Firefox

Though based on Firefox, the Tor Browser has several specialized features that set it apart, primarily aimed at maximizing user privacy and security:

  • No Browsing History: Unlike Firefox, which maintains a history of visited web pages, Tor Browser doesn't store any such data, ensuring your browsing activities remain unrecorded.
  • Disk Avoidance: In Firefox, web-related data like cookies and local storage are written to the computer's disk. Tor Browser avoids this, minimizing digital traces left behind after your browsing session.
  • Cookie Isolation: The Tor Browser goes beyond standard cookie management by employing a robust mechanism that segregates cookies based on the websites they originate from. This crucial layer of privacy significantly reduces the likelihood of cross-site tracking.
  • Security Extensions: Tor Browser comes bundled with security-focused extensions like HTTPS Everywhere, NoScript, and uBlock Origin. These extensions secure your connection and block potential tracking scripts and ads, whereas in Firefox you would need to install these separately.
  • Anti-Fingerprinting Measures: The Tor Browser has several built-in mechanisms to protect against browser fingerprinting—a method used to identify and track users based on their browser and device settings. These include a fixed window size and a uniform user agent string, features not standard in Firefox.
  • WebRTC Disabled: Web Real-Time Communication (WebRTC) can potentially leak your real IP address. While this feature is active in Firefox for real-time audio and video, it is disabled in the Tor Browser to ensure anonymity.
  • Fixed Safety Levels: The Tor Browser allows users to select from pre-configured safety levels that disable potentially risky features, like JavaScript, to varying extents, providing another layer of security that Firefox does not offer by default.

By designing with user privacy as the cornerstone, the Tor Browser offers a more secure and anonymous browsing experience, despite its foundational similarities to Firefox.

Unlocking the Power of Online Tor Browsing

Cloud-based Tor Browser Services

One way to experience the Tor network without installing anything is through cloud-based services like Browserling. Here, the Tor browser runs on a remote server, and you interact with it through your regular web browser. To access this:

  1. Navigate to Browserling's website.
  2. Choose the Tor browser option.
  3. Input the Onion URL you wish to visit and start browsing.

Instant Tor Browser Access with Short URLs

To make access even more effortless, we created a quick link that immediately launches a cloud-based Tor browser connected to the Tor network. For instance, using the link browserling.com/tor, you can get started with anonymous browsing in no time.

Why Choose an Online Tor Browser?

  • Convenience: An online Tor browser is incredibly user-friendly; no installation is required.
  • Platform Agnostic: Being web-based, you can access it from any device that has Internet connectivity.
  • Quick Setup : There's no need to configure any settings manually; it's all taken care of by Browserling.

Maintaining Anonymity

Even when using a cloud-based service, the Tor network safeguards your identity by routing your web traffic through multiple nodes, each only aware of the node immediately before and after it in the chain. Thus, your real IP address remains hidden from the websites you visit.

No IP Leakage Through JavaScript

The Tor browser's architecture prevents IP address leakage through any means, including JavaScript tricks that might otherwise reveal your real IP address. This adds an extra layer of security to your browsing activities.

Closing Thoughts

Using cloud-based services to access the Tor network provides a convenient way for Internet users to maintain their privacy and anonymity without needing to install additional software.
