Stop watching tutorials. Write code that runs.
Read one short idea, write the code in your browser and press Run. Tests show what passed, what broke and why, so you fix it while the idea is still fresh.
Free account. No card. Nothing to install.
Each level has short lessons with examples, then a checkpoint. Wrong answers show an explanation and a hint, you can retry as often as you need, and passing unlocks the next level. Finishing the final challenge completes the course and makes your certificate ready.

Why it sticks
Built for the moments people quit
Learning a technical subject tends to stall at the same few moments. Lab0 is designed around each one.
Where people usually stop: Setting up tools before you can even start
Nothing to install
Lessons, practice and checkpoints all run in your browser. Open a lesson and start.
Where people usually stop: Getting it wrong without knowing why
Explanations and hints
Checkpoints explain the answers and give a hint for what you missed. Retry as often as you need.
Where people usually stop: Sitting through what you already know
Skip ahead
Attempt a level checkpoint straight away. Pass it and the next level opens.
Where people usually stop: Losing your place between sessions
Progress that keeps
Lessons, submissions and checkpoints are saved to your account, so you pick up where you stopped.
Where people usually stop: Finishing with nothing to show for it
A certificate you can share
Finish the course for a certificate with its own public link, ready for LinkedIn or a CV.
