One vendor, one agent. Great for Claude — not for running Codex next to it.
Anthropic's official desktop app — bundles Claude chat, Claude Cowork, and a Claude Code surface with parallel sessions, an integrated terminal, file editor, diff viewer, and PR monitoring. MCP-native via Desktop Extensions (.mcpb).
The moment chat-only breaks: you want Codex running on the auth refactor in one pane while Claude Code chews on the migration in the next, both pointed at the same repo on different worktrees, with a real shell in pane three running the test suite and a fourth tailing logs. Claude Desktop's parallel sessions are excellent — for Claude. HyperCoder is the workbench when 'pick one model' isn't the answer.
// caveat · Claude Desktop is no longer just a chat app — Claude Code in-app gives you a sidebar of parallel sessions, an integrated terminal, file editor, diff viewer, PR monitoring, SSH, and Routines automation. MCP support there is the gold standard. If you only run Claude and you're on macOS or Windows, it's a strong default. HyperCoder's pitch is the Claude + Codex case: a real terminal that runs both, on Linux too.
