abtop

Like htop, but for your AI coding agents.

See every Claude Code and Codex CLI session at a glance — token usage, context window %, rate limits, child processes, open ports, and more.

demo

Why

Running 3+ agents across projects? See them all in one screen.
Hitting rate limits? Watch your quota in real-time.
Agent spawned a server and forgot to kill it? Orphan port detection.
Context window filling up? Per-session % bars with warnings.

All read-only. No API keys. No auth.

Install

macOS / Linux

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/graykode/abtop/releases/latest/download/abtop-installer.sh | sh

Cargo

cargo install abtop

Other

Pre-built binaries for all platforms are available on the GitHub Releases page.

Usage

abtop          # Launch TUI
abtop --once   # Print snapshot and exit
abtop --setup  # Install rate limit collection hook

Recommended terminal size: 120x40 or larger. Minimum 80x24 — panels hide gracefully when small.

Windows

abtop requires Unix tools (ps, lsof) and is not supported natively on Windows. Use WSL instead:

wsl --install
# Inside WSL:
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/graykode/abtop/releases/latest/download/abtop-installer.sh | sh
abtop

tmux

abtop works standalone, but running inside tmux unlocks session jumping — press Enter to switch directly to the pane running that agent.

tmux new -s work
# pane 0: abtop
# pane 1: claude (project A)
# pane 2: claude (project B)
# → Enter on a session in abtop jumps to its pane

Key Bindings

Key	Action

`Enter`	Jump to session terminal (tmux only)
`x`	Kill selected session

Privacy

abtop reads local files only. No API keys, no auth. Tool names and file paths are shown in the UI, but file contents and prompt text are never displayed. Session summaries are generated via claude --print, which makes its own API call — this is the only indirect network usage.
