abtop

Like btop, but for your AI coding agents.

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

On Linux, ensure sqlite3 is installed to enable monitoring for OpenCode sessions.

Cargo

Windows

Native support — no WSL required. Uses sysinfo for process info and host CPU/MEM metrics, and netstat -ano for listening ports. Windows has no load average, so LOAD is reported as 0. OpenCode session discovery additionally requires the sqlite3 CLI (winget install SQLite.SQLite); without it abtop prints a one-time warning to stderr.

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

Recommended terminal size: 120x40 or larger. Minimum 80x24 — panels hide gracefully when small.
Mouse capture is off by default so terminal drag selection and copy keep working. Launch with --mouse if you prefer click targets and wheel navigation.

Terminal Jump

Press Enter to focus the terminal running the selected agent. abtop supports cmux, tmux, and iTerm2 on macOS.
