AFK

Remote monitoring and interaction for Claude Code sessions. A macOS menu bar agent watches your Claude Code output, relays events through a Go backend over WebSocket, and an iOS app shows live session status, permission requests, and lets you send follow-up prompts — all end-to-end encrypted.

Architecture

┌─────────────────┐         WSS          ┌─────────────────┐

┌─────────────────┐                       ┌─────────────────┐
│   Claude Code    │                       │    iOS App       │
│  (JSONL output)  │                       │   (SwiftUI)      │
└─────────────────┘                       └─────────────────┘

The agent reads Claude Code's JSONL output files, normalizes events, and streams them to the backend over WebSocket. The backend stores events in PostgreSQL (unless relay-only mode is active) and forwards them to connected iOS clients. When the iOS app is backgrounded, APNs push notifications handle alerts for permission requests, errors, and session completion.

Content encryption uses Curve25519 ECDH key agreement between the agent and iOS app directly — the backend routes encrypted blobs without access to plaintext.

macOS Agent

Self-Hosting

git clone https://github.com/AFK-CLI/AFK.git
cd AFK
cp backend/.env.example backend/.env
# Edit backend/.env — at minimum set AFK_JWT_SECRET and AFK_DB_PASSWORD
docker compose --profile prod up -d

This starts PostgreSQL, the Go backend, nginx with TLS termination, and a Certbot sidecar for certificate renewal. See docs/self-hosting.md for TLS setup, APNs configuration, and the full environment variable reference.

Development

Backend (Go 1.25+, PostgreSQL):

cd backend
cp .env.example .env
# Start a local PostgreSQL instance (or use: docker compose --profile dev up -d postgres-dev)
go build ./cmd/server && ./server

Agent (macOS, Xcode 16+):

open agent/AFK-Agent.xcodeproj
# Or: cd agent && xcodebuild -scheme AFK-Agent -destination 'platform=macOS' build

iOS App (Xcode 16+):

open ios/AFK.xcodeproj
# Select a Simulator target → Cmd+R

Both Xcode projects read configuration from config/ xcconfig files. Copy the .xcconfig.example files and fill in your server URL. See docs/development.md for details.
