The terminals and coding agents on your own Mac and Linux computers, from a phone or any browser. End-to-end encrypted; your code never leaves the machine.

Luwu puts your tmux sessions on your phone, tablet or any browser. When Claude Code or Codex asks a question, your phone shows it and your answer goes back into the right terminal. Connections are direct when the network allows and relayed as ciphertext when it does not; the relay cannot read a byte.

• Answer agent questions and permission prompts from the lock screen
• Every tmux window on every computer, live, with scroll-back and new sessions
• Browser access at app.luwu.dev with nothing to install
• Files, prompts and notes where the agent works; share a window for an hour
• Per-device keys, owner approval for new devices, ~/.ssh and .env never shared
• Free for one computer; Basic, Pro and Team plans; Enterprise on your own servers

An online learning platform where a course is more than videos: quizzes inside lessons, timed exams, certificates with public verification, and a learner record that follows you.

• Timed exams with pass marks, and certificates with public verification
• Learning home and calendar: time studied, quiz accuracy, course progress
• Monthly and yearly subscriptions, single-course pricing, vouchers and affiliate codes
• Sign-in with Google, Apple, email or SMS code
• Multi-tenant: institutions run their own catalogue on the same platform
