Missing pieces I'm tackling this month: macOS/iOS builds (code-signing is the blocker), a Tailscale/WireGuard toggle so you don't need to expose port 8080, and agent-specific keybindings — Codex loves Ctrl-C, Claude Code prefers Ctrl-D.
Claude Code, Codex, OpenCode, and Hermes sessions that run for hours. What wasn't perfect was the workflow — every time I wanted to check a long-running task or nudge an agent, I'd open Termius, authenticate, tmux attach, scroll back, type, detach. On a phone? Forget it.So I wrote Relay. It's a tiny Go backend that sits on the Linux box and a React frontend that runs anywhere — browser, Android, Windows (macOS and iOS builds are next). The backend speaks the native protocols of each agent: Anthropic's CLI for Claude Code, OpenAI's for Codex, OpenCode's own socket, Hermes via its HTTP API. No wrapper scripts, no polling hacks. You log in once, pick an agent, and you're looking at a live terminal that survives device swaps.
What changed day-to-day: Session persistence— start a refactor on the desktop, walk away, pick up the exact same scrollback on the phone at the coffee shop. The tmux session never dies unless you kill it.File round-trips— drag a log file down, edit a prompt template up. Works over the same WebSocket tunnel, no scp needed.** Quota glance**— one click shows Anthropic/OpenAI token burn for the current billing cycle. Saved me from two surprise $0.00 weeks already.Credentials stay home— API keys, SSH keys, git credentials never leave the backend. The frontend is just a viewport.

If you've got a box collecting dust and a subscription to any of these agents, it's a 5-minute curl | bash
to try. Would love to hear what breaks on your hardware.
