Upload speed, how fast your computer can send data to a server on the Internet.

Measured in milliseconds (ms), ping indicates how responsive your Internet connection is. Jitter, based on multiple measures of pings, jitter measures the consistency of your Internet connection. Also measured in milliseconds, the smaller the jitter, the more stable an Internet connection. Speed Test works with a global network of over 5,000 testing servers. The app selects a server nearby your current location with a fast ping, which usually indicates a reliable Internet connection with good throughput.Starting Price: Free -

LAN Speed Test
TotuSoft
LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB drive, and Local Area Network (LAN) speeds (wired & wireless). First, you pick a folder to test to. This folder can be on a local drive or USB drive, etc. to test the drive speed, or a shared folder on your network to test your network speed. Next, LAN Speed Test builds a file in memory, then transfers it both ways (without effects of Windows/Mac file caching) while keeping track of the time, and then does the calculations for you. For more advanced users, you can test to LAN Speed Test Server instead of a shared folder to take the slower hard drives out of the process as you are testing from one computer's RAM to another computer's RAM. Simple concept and easy to use. You'll find that LAN Speed Test will quickly become one of your favorite network tools!

Basilisk
Basilisk
A XUL-based web browser demonstrating the Unified XUL Platform (UXP). This browser is a close twin to pre-Servo Firefox in how it operates. Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust. Basilisk is primarily a reference application for the development of the XUL platform it builds upon, and additionally a potential replacement for Firefox. Basilisk is development software. This means that it should be considered more or less "beta" at all times; it may have some bugs and is provided as-is, with potential defects.

Sleipnir
Fenrir
If you browse the web on a regular basis, there is no day when you don't see the text on any page. The web browser that displays them turns out to be a "tool for reading letters". Therefore, Fenrir's designers worked to beautifully draw the characters that are always visible for the longest time. To beautify the text on every page is to beautify the entire world of the web that you will see. Is it natural that the characters you see on your PC are jagged? With the evolution of display performance, the days when PC characters had to be coarse dots are long gone. Despite this, the characters in a typical browser still look like a retro game console. With the advent of Sleipnir, you can finally browse the web with beautiful modern characters on your PC. To maximize the natural beauty and readability of characters, Sleipnir uses uniquely tailored font rendering. The display, which makes a difference at a glance, is as good as a graphic tool used by professionals.Starting Price: Free -

Servo
Servo
Servo’s mission is to provide an independent, modular, embeddable web engine, which allows developers to deliver content and applications using web standards. Servo is written in Rust, and shares code with Mozilla Firefox and the wider Rust ecosystem. Since its creation in 2012, Servo has contributed to W3C/WHATWG web standards by reporting specification issues and submitting new cross-browser automated tests, and core team members have co-edited new standards that have been adopted by other browsers. As a result, the Servo project helps drive the entire web platform forward while building on a platform of reusable, modular technologies that implement web standards. Pre-built nightly snapshots allow developers to try Servo and report issues without building Servo locally. Now that we’ve released our first developer preview, we’ll be investing in formal security audits and improving our security practices using both existing libraries and Rust.Starting Price: Free -

Sidekick uses significantly less memory when you work with similar tabs. You spend 90% of your time working in web applications.

Turn your web applications into apps and put them in the sidebar to stay. Access anything with one click. Now you can be in every account on every platform simultaneously.

SponsorBlock
SponsorBlock
Users submit when a sponsor happens from the extension, and the extension automatically skips sponsors it knows about using a privacy-preserving query system. It also supports skipping other categories, such as intros, outros and reminders to subscribe, and skipping to the point with highlight. To prevent one submission with a lot of votes never being able to be replaced, I decided to use a weighted random distribution based on the equation on the right. This formula makes the first few votes matter a lot more than votes on a submission that already has a lot of votes. This gives newly submitted segments a better chance of being sent out to users to get votes. So, most users will get the best submission, but some users will get lesser votes submissions so that they can either be upvoted or downvoted.Starting Price: Free -

EFF
Privacy Badger is a browser extension that automatically learns to block invisible trackers.

To the advertiser, it’s like you suddenly disappeared. Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking.Starting Price: Free -

Get a faster browsing experience by blocking nasty web resources using Bluhell Firewall, the lightweight ad-blocker, and the tracking/privacy protector.

This is a lightweight extension (ie, 30KB compared to ~700KB of other popular adblockers), which was made with performance in mind. No configurable options, subscriptions, additional features, etc. You can turn the extension on/off at any time by clicking the toolbar button (Fx Desktop) or touching the menu item entry (Fx for Android).

Most computer software uses the operating system's DNS resolver that usually queries the configured ISP's DNS server using UDP protocol. This way works well for most people but, your ISP can see and control what website you can visit even when the website employs HTTPS security. Not only that, some ISPs can redirect, block or inject content into websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS.Starting Price: Free -
