CodePair by CodeSubmit vs Coterm

CodePair by CodeSubmit runs live coding interviews in a browser-based shared IDE, terminal, and repository. Hiring teams can observe how candidates write code and collaborate in an engineering-style project. Candidates may use ChatGPT, Claude, Gemini, and coding-agent workflows, while reviewers see prompts, responses, actions, and accepted edits. The terminal provides bash or zsh, Nix packages, language runtimes, PostgreSQL, and Redis. CodePair says reproducible Nix environments cover more than 100 languages and 1,000 packages and services. Git history, branches, shared commits, pull-request simulation, diffs, merge-conflict resolution, and GitHub or GitLab repositories support repository work. Automatic port detection, live reload, concurrent services, database connections, and preview links support running projects. Integrations include Greenhouse, Lever, Personio, Ashby, Zapier, Slack, and an Enterprise API. Plans start at $49 a month, billed monthly, with a seven-day trial.

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.
