Claude Code users now have a lightweight companion called Pulse. The dashboard runs locally on a machine with Node 18+, reads the JSONL logs that Claude writes to ~/.claude, and displays real‑time token usage, cost estimates, and session context. Pulse adds a notification hook that pushes approval requests straight to a phone without leaving the cloud today.

Because Claude stores every turn on disk, Pulse can auto‑snapshot active sessions and recover the last transcript with a single command. Users can set budgets per model or project; when an alert threshold is crossed, a push notification appears on the phone with allow/deny buttons, all achieved over 127.0.0.1 without external traffic in the instance.

Pulse exposes a minimal API on 127.0.0.1:4317, serving a full‑screen mascot view that shows Claude’s state and a rough ETA. The tool also offers a phone‑specific route that lets users pause, resume, or approve tool calls from a mobile browser, making the workflow seamless even when the laptop is off or on cellular.

Installation is a npx command or clone, and hooks are wired automatically with a script. Because everything runs locally, no telemetry leaks; the only network contact is the optional ntfy push. Pulse fills a niche for developers who want visibility on Claude’s cost and behavior.
