Pi Companion vs ValetFS

Pi Companion is an unofficial iOS companion app for the Pi coding agent (pi.dev) — browse your projects, read full chat history, and keep talking to your agents while away from your Mac. Start a task in your terminal, go for a walk, keep directing the agent from your phone, and come back to continue on the desktop — same session, no restarts. HOW IT WORKS A small open-source companion server runs on your Mac. It reads Pi's session files and drives Pi over its documented RPC protocol. The app connects directly to your Mac over your own network — no cloud, no accounts, no analytics. Use tools like Tailscale to reach your Mac from anywhere. FEATURES • Projects and workspaces: the folders you choose, grouped by git repo, with branches and live status • Full chat history: messages, thinking blocks, tool calls, and images • Send messages: continue any session from your phone; the terminal picks up exactly where you left off • New sessions and git worktrees, started from your phone • Model picker: Pi's full catalog across 15+ providers, switchable mid-session • Diffs: review each workspace's changes on your phone REQUIREMENTS A Mac running Pi (pi.dev), Bun, and the free companion server (link on the support page). This app is not affiliated with or endorsed by the Pi project.

Agents that read a repository issue, a web page or a tool description have been talked into reading credentials out loud. The key was never the target — the file it sat in was. A key written into a dotfile, an environment variable or a CI runner is readable by everything on that machine, forever, long after the job is done. ValetFS is the other way round. Your secrets live on your iPhone, in the Keychain, behind Face ID. When a tool on your computer needs one, ValetFS lends it — into memory, never to disk — and takes it back when you are finished. HOW IT WORKS • Install the ValetFS daemon on your computer and start it. It prints a QR code. • Scan the code with the app. The two are now paired. • Push a secret from your phone. It appears on the computer as an ordinary file that any tool can read — but it exists only in memory. • Close the app, and a grace timer starts. When it expires the daemon unmounts and wipes itself. Nothing is left behind on disk. END-TO-END ENCRYPTED Secrets are encrypted on your phone for one specific daemon, using X25519 key agreement and ChaCha20-Poly1305. The relay that carries them sees only ciphertext. We cannot read your secrets, and neither can anyone operating the infrastructure in between. BUILT FOR AGENTS Provision a session from the app and hand an AI agent a single connection key. The agent installs the daemon and joins — and you keep the authority to revoke it. One tap forgets the session, and a still-running daemon locks itself, unmounts, and wipes its memory. WHY NOT A CLOUD SECRETS MANAGER Federated identity solves this for workloads that run inside a cloud — they already have an identity to exchange for a short-lived token. Your laptop, your home server and the container your agent runs in have none, so they fall back to a file on disk. ValetFS gives that machine the thing it was missing: an authority that can say no, and that lives somewhere the machine cannot reach. NO ACCOUNT, NO TRACKING There is no sign-up and no login. No analytics SDK, no advertising, no behavioural tracking. The app is a client for infrastructure you can inspect — the daemon and the relay are both open source. REQUIRES A COMPUTER ValetFS is a companion to the ValetFS daemon, which runs on macOS or Linux and is a free open-source download. The app on its own has nothing to pair with.
