PRODUCTS

Three modules. One bridge from beginner to intermediate.

Built around one idea: get from “I don’t know what a variable is” to “I just built that” without ever leaving your phone.

The LabReal code editor

A real IDE in your pocket.

Write Python, JavaScript, TypeScript, Node.js, Java, C, C++, C#, Rust, SQL, or Bash. Tap run. See real output from a real interpreter. Syntax highlighting, error messages, and a custom keyboard built for code.

  • 11 languages, one editor
  • Sandboxed code execution
  • Custom keyboard for code
  • Real error messages
  • 30 free runs/day · unlimited on Pro

BadgesMilestones

Milestones that mean you got better.

First clean build. First time fixing a stack trace. First 7-day streak. Koda gives you 15 things to chase that prove you're getting better, and none of them is "you opened the app today."

  • 15 badges tied to real milestones
  • Daily streak counter
  • XP per concept mastered
  • Activity heatmap (1-year view)
  • Accuracy stats per language

HOW IT WORKS

A path, not a maze.

01

Pick your language

Choose from Python, JavaScript, TypeScript, Java, Rust, C, C++, C#, SQL, or Bash. Switch anytime.

language = "python" # or any of 11
02

Bite-sized lessons

Concept-first lessons, three to ten minutes each. Get unstuck and move on.

lesson.read() # 3-10 min each
03

Write real code

Every concept has a code exercise. Type, tap Run, see what happens. Real interpreter, real output.

>>> print("hello, koda")hello, koda
04

Build a streak. Level up.

XP, badges, daily streaks. The structure that keeps you coming back when motivation fades.

streak.days += 1 # +25 XP
PRICING

Simple pricing. No surprises.

FREQUENTLY ASKED QUESTIONS

Real answers.

Yes. We start at “what’s a variable” and take you to “I can solve real problems.” No prior coding experience required.

Most beginner apps cover beginner content well but stop there. Koda covers beginner AND intermediate, which is exactly the gap where most career-switchers get stuck.

Yes. Real Python, JavaScript, TypeScript, Java, and Rust interpreters running on our own infrastructure. You write code, we run it, you see what actually happens.

No. We assume zero coding background. If you can use a phone, you can start Koda.

Yes. Your subscription is managed by Apple or Google depending on where you bought it; cancel anytime from your device settings.

Eleven full tracks: Python, JavaScript, TypeScript, Java, Rust, C, C++, C#, SQL, Bash, and Node.js, every one with real code execution. Python and JavaScript cover most web/data work. TypeScript is the modern web. Java still runs enterprise. Rust is where systems are heading. Pick your path; the rest will be there when you need them.
