StackBlitz

StackBlitz is a collaborative online integrated development environment (IDE). The platform allows server-side software such as Node.js to be run entirely in the web browser, enabling fully online full-stack development. A number of web frameworks such as React, Next.js and Angular are supported.

History
StackBlitz was released to the public on August 2, 2017 by entrepreneur Eric Simons as an online integrated development environment for creating and sharing Angular and React projects. Prior to launching StackBlitz, Simons had attracted media attention by secretly living at AOL headquarters for two months in 2011 while working on a different startup company.

In May 2021, StackBlitz released WebContainers, a containerization solution that allowed server-side runtime environments such as Node.js to operate fully with web browsers. The company stated that the technology could boot development environments in less than a second, and was more secure than local environments due to running fully within the browser sandbox.

Features
StackBlitz offers an online integrated development environment that operates fully within a user's web browser as opposed to a more traditional local development environment. The software primarily emphasizes JavaScript development and has a large number of web framework templates readily available. Other Node.js, Python and PHP projects are also supported.
