This startup is building a new generation of web browsers, called “containers”, that work like operating systems. Containers are like virtual machines (VM) in that they run programs inside them, but they’re a lot more flexible. You can build a container that can run a Ruby or a Python, for example, and you can run a container that runs a ton of different kinds of programs. Containers can also be used to run a group of VMs, and VMs can run each other, too. The tech is still in its early days, but it’s a promising tech that’s been used to run the Linux operating system.
