Scarf

What Scarf does

Scarf is written in pure Swift 6 and SwiftUI, with no Electron. It opens Hermes state read-only and sends management actions through the hermes CLI, so it cannot corrupt the agent's data. It works with a local ~/.hermes/ directory or any number of remote hosts over plain SSH, using your existing ssh config, with no companion service in between.

The Mac app provides live dashboards, full-text search, activity feeds and cost breakdowns, plus chat over ACP or a real terminal. It detects each host's Hermes version and hides newer-only features on older hosts, and Hermes v0.6 through v0.21 are listed as working. ScarfGo, the iPhone companion, is free on the App Store and offers project-scoped chat with session resume, a skills browser, a memory editor, cron and per-server profile switching. The UI is available in seven languages.

Key features

• Dashboards for every session, message, tool call, token and dollar
• Chat with streaming over ACP or a real terminal
• Edit memory and skills, and manage cron, gateways and MCP servers from a GUI
• Local and multiple remote hosts over plain SSH with no middleman service
• Version-adaptive interface covering Hermes v0.6 through v0.21
• ScarfGo iPhone companion with an on-device Ed25519 key stored in the iOS Keychain

When to use it

• Checking on a Hermes Agent running on a home server from your iPhone
• Reviewing token and cost breakdowns across sessions
• Editing Hermes memory files and cron jobs without touching YAML

Who it is for: Hermes Agent users on Mac or iPhone who want a native graphical front end instead of the terminal alone.

How it fits with Hermes Agent
