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, Linux, and Windows.

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

Windows

Native support — no WSL required. Uses sysinfo for process info and netstat -ano for listening ports.

powershell -c "irm https://github.com/graykode/abtop/releases/latest/download/abtop-installer.ps1 | iex"

Or cargo install abtop from any terminal with Git in PATH. Claude Code config is resolved automatically from %USERPROFILE%\.claude.

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.

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

12 built-in themes, including 4 colorblind-friendly options (high-contrast, protanopia, deuteranopia, tritanopia). Press t to cycle at runtime, or launch with --theme <name>. Your choice is saved to ~/.config/abtop/config.toml.

btop (default)	dracula	catppuccin

tokyo-night	gruvbox	nord

Colorblind-friendly themes:

high-contrast	protanopia

deuteranopia	tritanopia

Light themes (light — Solarized cream, white — GitHub-style pure white) for bright terminals:

light	white

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"]

Language

abtop auto-detects the UI language from LANG — any value starting with zh switches to Simplified Chinese, otherwise English. Override with ABTOP_LANG=zh or ABTOP_LANG=en.

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.
