In their own words
Coterm
Coterm is a native macOS workspace for two developers sharing a terminal, browser, and coding-agent session in real time. A live room lets both people join, follow terminal activity, see participants, and share previews. The shared workflow lists Claude Code, Codex, OpenCode, Gemini CLI, Aider, Amp, Cursor Agent, and other CLI agents. Coterm uses a Ghostty-based terminal with vertical tabs, a notification panel, and a socket control API. A CLI and Unix socket expose programmatic commands, while integration hooks can be configured for Claude Code, Amp, Cursor, Gemini, and Kiro CLI. The Mac app runs locally without a Coterm-hosted account service. Collaboration components can run in the user's Cloudflare account. Installation is available through DMG or Homebrew on macOS 14.0 or later, for Apple Silicon and Intel. An iOS companion is in beta. Coterm is free under GPL-3.0-or-later.
Pop
Pop is a videoconferencing and screen-sharing service built around shared control of a computer. Participants can use their own mouse and keyboard on the shared screen, while voice, video, drawing, and highlighting support real-time communication. People can join a meeting from a link before registering, using a laptop or smartphone. The listed joining options include Chrome, Firefox, Safari, mobile browsers, and Mac, Windows, and Linux. Users can start a meeting from Slack with a slash command or call button, and connect Google Calendar to manage scheduled Pop meetings. Pop says meeting traffic is encrypted in transit and that it does not store or record meeting media. Its security information distinguishes one-to-one calls, which it says are end-to-end encrypted, from calls with three or more participants, where an SFU decrypts and re-encrypts media. Pro is listed at $0 while in beta and includes unlimited meetings with no time limit. Starter is free. Enterprise costs $25 per user per month and starts at 40 licenses for $12K/year.
