# Pebble Stream Documentation

> Pebble Stream technology compiles the business logic trapped in spreadsheets into executable libraries called Pebbles. Business, accounting, and financial analysts that create Pebble Stream compatible spreadsheets are called Pebblers. Software developers can execute Pebbles in cloud applications using the Pebble Stream runtime.
