Agora Flat provides web and desktop clients for creating, joining, and scheduling online classrooms. Teachers and participants can combine an interactive whiteboard with live audio, video, messaging, screen sharing, and course materials, then replay recorded classroom activity. The open-source client may be used commercially, but the project does not provide commercial customization, deployment assistance, or customer support.

Thorium Reader is a desktop EPUB reader for Windows, macOS, and Linux. It imports books from local directories or OPDS feeds, then lets readers adjust layouts, navigate by table of contents or page list, and save bookmarks, with explicit attention to screen-reader accessibility. Builds made only from the public source support the basic LCP encryption profile; broader production-grade LCP support requires an additional component.

Piano Trainer turns scales, chords, and the circle of fifths into interactive desktop exercises. Learners can respond with a MIDI keyboard or the computer keyboard, then reinforce recall through quizzes, hard mode, and shuffled practice. Free cross-platform builds are available. It works best as a hands-on reference and repetition tool for self-paced learners rather than as a complete structured piano course.

PSLab App connects to Pocket Science Lab open hardware over USB and turns a phone or computer into an experiment control and data collection interface. The device can act as an oscilloscope, waveform generator, frequency counter, programmable voltage or current source, and data logger. The app spans mobile, desktop, and web, but the core experiments require PSLab hardware.
