Scrum Programming Language

An intentional programming language: you write ceremonies, it compiles to Java.

LEVEL 02 SPRINT ZERO

A language that compiles ceremonies

programming by intent · compiles to Java

Scrum Programming Language

A real language where you code entirely in ceremonies — sprint goals, epics, user stories. Yes, really. Sprint zero compiles. Say hello to Scrummy.

Explore →

SCRUM is a programming language I designed and built myself. Not a framework, not a DSL bolted onto something else — an actual language with its own compiler. You write the ceremonies you already argue about in stand-up, and it compiles them to deterministic Java. The AI runs at compile time, not at runtime, so the binary you ship behaves the same every single run.

hello-world.scrum

#SPRINTGOAL Deliver our first Scrum program

EPIC "SampleStories"

    USER STORY "HelloWorld"

        #REVIEW Our first Scrum Program
        SAY "Hello world!"

    END OF STORY

END OF EPIC

the ceremonies are the syntax

intent.scrum

EPIC "SampleStories"

    USER STORY "Greeting"

        #INTENT
        Display a friendly greeting to the user.
        #END INTENT

    END OF STORY

END OF EPIC

#INTENT states the what — the compiler writes the how, once, into Java
