ServiceNow Open Source Apps I Found in the Wild on GitHub
Over the years I have found a lot of useful ServiceNow projects just by stumbling across them on GitHub. Some are full applications, others are a single script include that solves one annoying problem. If you are looking to build something or try something someone else has built, searching GitHub with the right keywords goes a long way.
BookNow
A booking and reservation system built on the platform. Useful if you need room booking, equipment checkout, or any resource scheduling.

InterviewNow
An applicant tracking system built as a scoped app. Originally a Knowledge 17 hackathon project that turned into something more.

K19 CCW1547 Lab App
A lab application from Knowledge 19 created by the ServiceNow events team. Good reference for how official training content is structured.

Service Portal Widget Library
A collection of reusable Service Portal widgets by Platform Experience. If you build portals, this is worth digging through for patterns and ready-to-use components.

SN Google Translate
A single UI Script that adds Google Translate to your instance. Minimal footprint, does one thing well.
https://github.com/MBahrSNC/snGoogleTranslate
SN Service Catalog Widget
Custom catalog variable widgets by Cody Esmay. Uses macro variables with font-awesome icons for custom-looking checkboxes that still work with client scripts and UI policies.

How to find more
Searching GitHub for servicenow, service-now, snc-, or x_snc_ will turn up a lot of open-source ServiceNow projects. Most are shared by consultants and developers who had a problem to solve and decided to share the result. Some of the best finds come from looking at what people present at Knowledge and CreatorCon — the demo apps and lab content are usually on GitHub under the session code.
