What happened to Lektur.org?
discontinued The registry marked Lektur.org discontinued on 2026-08-31: its check failed three consecutive times. Last successful sync: 2026-08-20.
Lektur.org helps educational content creators craft highly-engaging, interactive lectures. The editor features pre-made content blocks specifically designed for your subject (interactive functions, maps, sheet music, chessboard, virtual blackboard, etc). It allows teachers to create interactive learning experiences and students to learn by interacting with the content.
Live alternatives
No active same-category alternatives in the registry yet. The tools index carries everything else that is live.
How this was decided
Not an editorial call. Lektur.org's check failed three syncs in a
row, and the 3-miss rule marks it
discontinued automatically. If the vendor page comes back, the
registry restores it on its own: warn first, then
active. Both directions are recorded as events.
