KESTREL-9 · THE DEVELOPER PROTOCOL
Learn Python by bringing
a dead spaceship back to life.
A 30-day gamified course where every line of code you write does something real: wakes a reactor, routes power, kills a tumble, calls home. No videos. No quizzes-for-quizzes'-sake. A terminal, a mission, and a ship that remembers what you did to her.
Days 1–3 free · one-time $19 unlocks all 30 · no subscription
⚛ A real ship, not a sandbox
The probe KESTREL-9 is dark and tumbling. You have a hardline to her flight computer. import ship and bring her back — state persists, mistakes trip breakers, and the exterior camera shows it all.
▸ 30 days, one protocol
Variables to files to APIs to a capstone you design. Boss terminals at days 7, 14 and 21. Real code runs in a sandboxed interpreter with real tracebacks — errors are curriculum, not failure.
⚡ Progress that fights back
XP, ranks, streaks that freeze instead of reset, achievements with teeth, and a campaign map that lights up as you clear it. Finish and graduate with a certificate and Developer Mode.
$19. Once.
Days 1–3 are free — no card required. If the protocol is for you, one payment unlocks all 30 days, the bonus arcade, the capstone, and graduation. That's it. No subscription, no upsells.
