For OpenBoard alternatives, have a teacher run a real classroom segment on the intended board or projector.
- Write with a pen, move objects, import a PDF, and annotate a web or media asset.
- Test latency, palm rejection, multi-touch, and accessibility.
- Save the lesson, reopen it, and export it for absent students.
- Check student-device sharing and offline operation.
- Verify hardware driver support before buying licenses or replacing equipment.
The decisive metric is whether teaching flows naturally, not how many drawing tools are listed.
