ClassroomShell
A read-mostly browser terminal that lets coding bootcamp instructors broadcast a live Linux shell to a class of 30 students, with private breakout terminals for hands-on exercises.
Coding bootcamp instructors and high school AP Computer Science teachers running remote or hybrid classes
- Instructor view with one-click broadcast, private 'raise hand' terminal, and a 30-seat student roster
- Pre-loaded exercise environments (Python REPL, Git workflow, Node starter) so students don't waste class time on setup
- Auto-grading of command-line exercises by checking exit codes and file outputs against an instructor-defined rubric
- Session replay library so absent students can scrub through the recorded shell exactly as it happened
Browser terminal sharing is now easy enough to run in any classroom, but existing tools assume developer peer collaboration, not a teacher controlling 30 students who have never used a shell before.
Confirmed niche exists: shellshare.net's own docs name the 'teacher sharing terminal with students' use case, and sshx.io lists teaching as a primary use case, but direct classroom-broadcast demand remains niche within a niche.shellshare - live terminal broadcast ↗sshx · share collaborative terminals ↗
Narrower than starting score implied: at least three tools (shellshare, sshx, shell-now) already explicitly target teaching/terminal-sharing. The specific '30-student breakout + admin controls' layer is unclaimed, but the broadcast-to-class concept is attempted.shellshare - live terminal broadcast ↗sshx · share collaborative terminals ↗GitHub - STRRL/shell-now: Share your terminal in the browser in seconds ↗
All close competitors (shellshare, sshx, shell-now) are free or open-source; AP CS teachers have near-zero budgets, and bootcamp instructors don't purchase tools — their schools do. Willingness-to-pay evidence from instructors is weak.Codio | Hands-On Learning Experience Platform | Dev, Data, AI, Cyber ↗Pricing | Codecademy ↗
Remote/hybrid instruction is structurally permanent post-COVID, browser-shell tech is now commodity, and coding-bootcamp/AP CS enrollment continues to grow — durable tailwinds.The 24 Best Online Bootcamps of 2026 - Course Report ↗Codecademy Live Learning Bootcamps ↗
The core tech is already shipped as a single binary in shell-now (ttyd + cloudflared); layering instructor controls, breakout sessions, and session lifecycle is a modest frontend scope over proven infra.GitHub - STRRL/shell-now: Share your terminal in the browser in seconds ↗
