Welcome to PLDB: a Programming Language Database!
PLDB is a comprehensive database of programming languages and their features. The focus is on programming languages, but the database also includes other languages and entities one degree away--from popular high level plain text formats to binary specifications and beyond.
PLDB is for two groups of people:

All data and source code used to generate this site are on GitHub.
PLDB is an entirely static site. PLDB.io is served via ScrollHub. You can clone the source to PLDB and build it locally and use PLDB entirely offline on your own machine.
This site is powered by information and software from so many people and organizations, a few of which are listed on the acknowledgements page.

The URL for the official PLDB site is https://pldb.io. DNS will take that domain name and send your browser an IPv4 address. Your browser will send a request to that address which will reach a DigitalOcean server running ScrollHub. That server will send you the HTML, CSS, Javascript, PNGs, SVGs and JSON that make up the built website.
In case there's a problem with ScrollHub, you should be able to access the exact same site locally by downloading the source.
If ScrollHub AND GitHub were to go down at the same time...well that's why it's good to regularly download the entire source code of the site to your own machine! You can do that with:
git clone https://github.com/breck7/pldb.git
# Then to keep it updated:
cd pldb
git pull
The site owes its existence to a kind (but firm) Internet commenter who told Breck Yunits to "learn to research properly" if he wanted to make his languages any good.
