Cctop

cctop

Interactive top-style monitor for Claude Code sessions. Know at a glance what
Claude is working on, how much context it has left, and which sessions are
waiting for input.

Features

- All your sessions at a glance — every running Claude Code session in one
  table: process stats (PID, memory, CPU, uptime), busy/idle state, context
  size, model, host app (terminal or IDE), project, git branch, and last prompt.
- Sub-agent & process tree — live sub-agents (with their latest turn) and
  each session's sub-processes, open and orphaned TCP ports.
- Live TUI — navigate with the keyboard, open a per-session detail view, and
  filter and sort on the fly; piped or run with --once it prints a single frame.
  The sort mode, refresh interval, and notifications toggle are remembered
  across restarts, and the visible columns are configurable
  (see Customising the columns).
- Get pinged when a session needs you *(opt-in)* — press n and cctop
  rings the terminal bell and raises a desktop notification (OSC 9, supported
  by iTerm2, Ghostty, kitty, WezTerm, Windows Terminal) whenever a busy
  session finishes its turn and waits for your input — so you can look away
  while agents run. Works with tmux monitor-bell window flags too.
- Status at a glance — busy sessions are green, idle red; CPU and context
  heat toward red as they climb; the selected session is marked with a blue bar.
- Which session rang? — the other half of that ping: a session that stops
  wears a hollow ○ for 30 seconds, the summary keeps naming the last one to
  ding (Bell: ○ cctop · pid 1737989 · 4s ago) until you answer it, and b jumps
  straight to it. A bell out of one of a dozen panes is never a mystery, even
  if you were away when it rang — and it reads the same whether the bell came
  from cctop's…
