Capabilities

Everything happens
in one place

Real-time monitoring

Live activity states for every session: thinking, writing, reading, searching, compacting.

Multi-agent support

Monitors Claude Code (CLI & Desktop), Cursor, pi, and OpenCode side-by-side. Use --agent to filter.

Cost tracking

Automatic token counting and USD cost estimation per session.

Activity sparklines

Visual intensity graphs to spot which sessions are most active over time.

Zero modifications

Reads existing session data (JSONL and SQLite) from each agent. Purely observational — never touches agent files.

Fast & lightweight

FSEvents-based. Single Go binary, no runtime dependencies, minimal CPU.

Three interfaces

TUI, macOS menu bar, or HTTP API. Same core, mix and match as needed.

Interfaces
