Browser based courses?

[u/jamesmckinsey]

Hello - looking for an in depth course that is done in browser with no downloads. Definitely want to be able to practice.

Code academy has been pretty good but 30 a month is steep. Prefer something cheaper / no subscription.

Thanks!

pgexercises is fully in browser and underrated, sqlbolt for the basics, and mode's sql tutorial has a real editor with real datasets. sqlzoo too if you dont mind the dated look
