About

ScarfGo

Features
Read full description

ScarfGo is the iPhone companion to Scarf, the open-source macOS GUI for the Hermes AI agent. It connects from your phone to a Hermes server you operate — your Mac, a home Linux box, a cloud VM, anything reachable over SSH — and lets you run sessions, browse memory, manage cron jobs, and resume conversations on the go. A fully native iOS app, not a web view or a remote desktop. ScarfGo speaks SSH directly using a pure-Swift implementation, reads Hermes state via SFTP and SQLite snapshots, and streams real-time agent output over the Agent Client Protocol on a long-lived SSH exec channel. Every byte stays between your device and the Hermes host you configured. What you can do: • Multi-server. Configure as many Hermes hosts as you like and switch between them with a tap. Soft Disconnect keeps your credentials cached; Forget wipes a server end-to-end. • Dashboard. Stats and the 25 most recent sessions, with project badges so you can tell at a glance which work is which. • Project-scoped chat. Pick a project from your registry and ScarfGo writes the same Scarf-managed AGENTS.md context block the Mac app does, so the agent boots with the right project context. The resulting session is attributed correctly across both clients. • Session resume. Tap any row on the Dashboard to open that session's transcript in Chat. CLI-started sessions hydrate from the Hermes state database; ACP sessions show an empty-state because Hermes does not persist ACP transcripts to the database. • Memory editor. Read and edit MEMORY.md and USER.md with a Saved indicator that survives keyboard dismissal and a one-tap Revert. • Cron list. Human-readable schedules ("Every 6 hours", "Weekdays at 09:00") instead of raw cron expressions, plus a relative next-run estimate. Read-only in this release; editing comes in a future update. • Skills browser. Read-only category tree with the SKILL.md frontmatter chips (allowed tools, related skills, dependencies) the Mac app shows. • Settings viewer. Read-only inspection of your config.yaml. Edit values from the Mac app or a remote shell. Privacy. ScarfGo does not collect, transmit, or store your data on any server controlled by the developer. There are no analytics, no telemetry, no ad identifiers. SSH keys are generated on-device and stored in the iOS Keychain with the ThisDeviceOnly attribute, so they are unreachable while the device is locked and never sync to iCloud. The complete privacy policy lives at awizemann.github.io/scarf/privacy. Open-source under the MIT license. Source, issue tracker, and contributor docs at github.com/awizemann/scarf. Bug reports tagged component:scarfgo go straight to the developer. Requirements. iOS 18.0 or later. An SSH-reachable Hermes server (Hermes v0.10.0 or later recommended; full v0.11.0 features supported). Your phone needs to be able to reach that server over the network, for example on the same Wi-Fi or at a public address that accepts SSH connections. ScarfGo itself does not provide any network or VPN service.
