abtop

Like btop, 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. Claude Code and Codex CLI sessions are discovered from local process/file state, so multiple active profiles are supported across macOS and Linux.

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
abtop --theme dracula    # Launch with a specific theme

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

Themes

Configuration

~/.config/abtop/config.toml supports:

theme = "btop"
# Hide specific agent CLIs from the TUI (case-insensitive).
# Useful if you only use one agent and want a cleaner view.
hidden_agents = ["codex"]

Key Bindings

Key Action
↑/↓ or k/j Select session
Enter Jump to session terminal (tmux only)
x Kill selected session
X Kill all orphan ports
t Cycle theme
1–5 Toggle panel visibility
Esc Open/close config page
q Quit
r Force refresh

Privacy

abtop reads local files and local process/open-file metadata 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.

Acknowledgements

Huge thanks to @tbouquet for driving much of abtop's recent shape — themes, config overlay and panel toggles, session filtering, subagent tree view, the context window gauge with compaction detection, plus a steady stream of fixes and security hardening along the way.
