# Intro to Firebolt

**Firebolt****®** **is an application platform to build apps for TVs, set-top boxes, and other connected home devices.** Comprised of an extensive family of APIs which are paired with lightweight guidelines, Firebolt empowers app developers to write once and deploy to any supported device.

**Firebolt is open-source and maintained by one of the largest telecommunication companies in the world.** The platform is RPC-based and includes an autogenerated JavaScript client, allowing off-the-shelf usage for JavaScript apps. Being RPC-based also gives developers flexibility to create custom clients for any other programming language.
