'''Pony''' (also referred to as '''ponylang''') is a [[Free software|free]] and [[open-source|open source]], object-oriented, [[actor model]], capabilities-secure, high performance programming language.{{Sfn|Allen|2024}}<ref name="hnoon">{{cite web |author=Alex Lashkov |date=26 July 2023 |title=The New Wave of Programming Languages: Pony, Zig, Crystal, Vlang, and Julia |url=https://hackernoon.com/the-new-wave-of-programming-languages-exploring-the-hidden-gems |access-date=24 December 2024 |website=Hackernoon}}</ref> Pony's reference capabilities allow even mutable data to be safely passed ''by reference'' between actors.
