OSPOS

Open Source Point Of Sale (“OSPOS”) is an aptly-named web-based point of sale system, which can be installed locally or remotely, and is packaged with Docker for easy installation, and will even run on a Raspberry Pi. It has many features in addition to basic POS operation, including customer management, barcode printing, numerous reporting tools, and the ability to help track inventory.

OSPOS is written primary in PHP with a MySQL backend, and is made available under an MIT license.

SambaPOS

SambaPOS is a point of sale system specifically designed for restaurants, and supports multiple languages and currencies. While a newer commercial version is available which is unfortunately proprietary, the slightly older SambaPOS 3 is available as open-source under a GPLv3 license. Written in C#, SambaPOS 3's source can be found on GitHub. Targeted at a Windows platform, it seems like it may be a good choice for businesses with relatively simple needs. SambaPOS open-source is really beneficial for businesses involved in restaurants and hotels.

WallacePOS

WallacePOS is a web-based point of sale system, written in PHP, which is designed to be compatible with standard POS hardware like printers, cash drawers, and barcode readers. Since it's written to run inside of a browser, it should work with any modern operating system.
