I am looking for a flashcards webapp that I can install on my webserver.
Requirements:
- Spaced repetition,
- Open source,
- Installable on my own server,
- 10000 persons can use it simultaneously, each reviewing a few minutes to an hour per day,
No need for mobile/computer apps nor synchronization, 100% web UI is OK.
I love Anki but its web UI is proprietary.
