A galaxy of coding missions for kids

Learn to code,
one planet at a time.

Every mission you finish lights up your galaxy map, earns XP and raises your astronaut rank — from your very first Scratch game all the way to real Python, HTML and JavaScript projects.

Blast off in three steps

No installs, no setup, no experience needed. Just a map, a mission and you.

1

Create your explorer

Pick a colour, tell us your age, and we place you on the right planet — under-8s launch in the Junior galaxy.

2

Follow the road

A winding road connects every mission. Open the next glowing node, read the briefing, and build something real.

3

Rank up

Finishing missions lights up your map, earns XP and raises your astronaut rank. Confetti included.

Built like a game.
Teaches like a mentor.

A living galaxy map

Your progress is a place, not a percentage. Completed missions shine green, the next one bounces and calls you, and locked worlds wait down the road.

XP & astronaut ranks

Every mission pays XP. Climb from Cadet to Commander and watch your bar fill.

Junior galaxy for under-8s

Little explorers get their own gentler track — and move up automatically on their 8th birthday.

Mission Control for teachers

Teachers see every student's road at a glance and can edit the whole curriculum — no code needed.

Real tools, real skills

Missions use the same tools real programmers learn with — from Scratch blocks to Python, HTML & CSS and JavaScript.

The planets you will visit

The real curriculum, straight from the galaxy — five worlds for explorers 8 and up, plus a Junior galaxy for the youngest cadets.
