Parallax is a Windows/Linux desktop workspace that runs Claude Code, Codex, Antigravity or any shell in named panes with a built-in editor, local Git, session directory, voice chat, and saved layouts—agents stay independent (no auto-orchestration); local-only data; subscription required ($11.99/mo or $99.99/yr USD) plus your provider plans.
Helicon is a free MIT desktop (and browser) client for Meta’s Muse Code CLI: project sidebars, session history, inline diffs, approval queue and cost meter at published API rates—on the Muse Code login you already have. Native Windows (no WSL required), universal macOS DMG, Linux AppImage/source; not affiliated with Meta. Fills the “GUI for Muse Code” gap while Meta ships TUI-first.
MIT Tauri app runs Claude Code/Codex/OpenCode/Antigravity/Grok Build side-by-side with approvals and session resume; keep agents on the PC, then reconnect to the same live terminals from phone via your own relay/LAN/VPN.
