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:

browserling.com/chrome/110/catonmat.net/new-browserling-ui

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!

Pinned post

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.

Online Tor Browser FAQ

This is an excerpt from my popular Tor Browser Guide. In this excerpt, I'll cover the basics of using an online Tor browser, how it protects your privacy, and some common questions about the onion network security.

Online Tor Browser Demo

I and my team have created an online Tor browser version. Head over to browserling.com/tor use our cloud-based Tor browser. It works straight from your browser and there's nothing to download or install. Just click and go!

Online Tor Browser FAQ

What is an Online Tor Browser?

An Online Tor Browser is a cloud-based version of the Tor Browser that you can use without installing anything on your device. It lets you test your Onion websites by routing your traffic through the Tor network, just like the regular Tor Browser. This is useful if you can't install Tor or want extra privacy when using a shared or restricted device.

Can an online Tor browser protect against browser exploits and zero-day vulnerabilities?

Yes, an online Tor browser does protect against browser exploits and zero-day vulnerabilities. If an attacker finds a zero-day in an online Tor browser, they can only affect the virtual machine (VM) running it, not your actual device. Since the browser resets after each session, the attacks won't stick.

How do threat actors de-anonymize Tor users?

Attackers use correlation attacks, compromised exit nodes, and JavaScript-based exploits to track users. Nation-state actors may monitor entry and exit traffic to identify patterns. Using an online Tor browser adds an extra layer of protection.

Can a malicious exit node inject malware into Tor traffic?

Yes, exit nodes can modify unencrypted HTTP traffic. If you're not using HTTPS, an attacker controlling an exit node could alter content or inject malicious payloads. When using an online Tor browser, always make sure you're visiting HTTPS sites.

How do government agencies track Tor users?

Agencies like the NSA and FBI use traffic correlation, compromised relays, and malware exploits to track users. If they control both the entry and exit nodes a user is passing through, they can analyze timing and volume patterns to reveal identities. An online Tor browser prevents it as entry node runs in the cloud.

Can Tor users be tracked via WebRTC leaks?

No, WebRTC is disabled in online Tor Browser by default to prevent IP leaks. However, if a user enables WebRTC or modifies the browser settings, the remote servers's IP address could be exposed. Your IP will not be exposed as you haven't connected directly to Tor network.

What is a Sybil attack, and how does it affect Tor?

A Sybil attack happens when an attacker runs many malicious Tor relays to manipulate network traffic. This could allow them to monitor users' paths or perform deanonymization attacks. The Tor Project actively monitors and removes bad nodes to prevent this.

Can Tor be exploited for remote code execution (RCE) attacks?

Like any browser, if a Tor user visits a malicious website with an unpatched exploit, an attacker could achieve RCE. This has happened before, with law enforcement using Firefox vulnerabilities to unmask users.

Why do security researchers analyze Tor traffic?

Researchers study Tor traffic to understand anonymity risks, detect malicious use, and improve security. Some focus on finding ways to strengthen Tor, while others (like law enforcement) track activity on the dark web.

How do zero-day exploit developers test vulnerabilities in Tor?

Exploit developers often test Tor vulnerabilities in isolated environments using virtual machines and sandboxing. They look for ways to bypass protections like fingerprinting resistance and sandboxing, and sometimes pass their findings to security firms or government agencies.

What is Browserling?

Browserling is an online service that lets you use different web browsers in a virtual machine. It runs browsers in the cloud, so you don't have to download or install anything on your computer. You can use it to access an online Tor browser, which helps you test your onion websites.

Who Uses Browserling?

Browserling has now become the go-to online Tor browser platform for cybersecurity experts, onion website developers, and cypherpunks, and it's used by hundreds of thousands of users around the world every month. Browserling's customers include governments, states, cities, banks, stock exchanges, universities, newspapers, Fortune 100, Fortune 500 companies, and private multi-billion dollar companies.
