This site provides a free tool to test your webcam online and check if it is working properly. In other words, you can test it directly from your browser without the need to install third-party software. Despite such an easy way, you can start testing your webcam “in one click” on different devices, including laptops, smartphones, TVs, tablets and others. Regardless of the device and the operating system, as a result of testing, you will not only know if your webcam is working, but also find out a lot of useful information about it (i.e, webcam name, resolution, frame rate, number of colors, image quality and many other specifications). In addition, if the testing tool detects any problems with your web camera, you will receive some hints on how to fix them. After completing the webcam testing, among other things, you can take photos with your webcam and download them. Also you can view it in fullscreen and rate your webcam.

This website provides a simple online mic test that allows you to check if microphone is working properly. Since it’s a browser microphone test, you don’t have to download or install any third-party software. Moreover, even if it may seem too simple, MicTests.Com will test your microphone regardless of its type or the device and operating system you are using. And to surprise you even more, this mic test will display a lot of useful information about your microphone (for example, its name, number of audio channels, latency, sample size and sample rate, as well as if it supports echo cancellation or noise suppression). In addition, if the tester will detect any problems with your microphone, you will receive tips on how to fix them.

Galène (or sometimes Galene) is a videoconference server (an “SFU”) that is easy to deploy and that requires moderate server resources. It was originally designed for lectures and conferences (where a single speaker streams audio and video to hundreds or thousands of users), but later evolved to be useful for student practicals (where users are divided into many small groups), and meetings (where a few users interact with each other).

Galène's server side is implemented in Go, and uses the Pion implementation of WebRTC. The server is regularly tested on Linux/amd64 and Linux/arm64; it has been shown to run on Linux/armv7 and Linux/mips (OpenWRT), and even on Windows. It should in principle be portable to other systems, including Mac OS X. The client is implemented in Javascript, and works on recent versions of all major web browsers, both on desktop and mobile (but see below for caveats with specific browsers).

While traffic is encrypted and authenticated from sender to server and again from server to receiver, Galène does not perform end-to-end encryption: anyone who controls the server might, in principle, be able to access the data being exchanged. For best security, you should install your own server.
