abtop Gives Developers a Real-Time Dashboard for Parallel AI Coding Agents
abtop is a free, open-source Rust TUI that gives you a real-time htop-style dashboard for all your Claude Code and Codex CLI sessions at once
- abtop is a free, open-source Rust TUI that monitors Claude Code, Codex CLI, and OpenCode sessions in real time from one terminal screen.
- Tracks token usage, context window fill %, rate limits, child processes, orphan ports, and git status per session -- no API key needed.
- Works by reading local process state and session files via
psandlsof; the only network call is an optional session summary viaclaude --print. - tmux integration lets you press Enter on any session in the dashboard to jump directly to that agent's terminal pane.
- Subagent tree view and memory panel are Claude Code-only; no historical metrics -- it's a real-time monitor, not a metrics store.
- MIT licensed, 2,600+ stars, installable via one curl command or
cargo install abtop.
abtop is the monitoring tool that should have existed the moment developers started running more than one AI coding agent at a time. Built in Rust by graykode, it drops a dense, keyboard-driven terminal dashboard onto your screen that tracks every active Claude Code and Codex CLI session in real time -- token spend, context window fill, rate limits, spawned child processes, and open ports, all in one place. Think htop, but the metrics that matter are tokens and quotas instead of CPU and RAM.
The problem it solves
If you've ever opened three terminal windows running three Claude Code sessions and lost track of which one is stuck, which one is bleeding tokens, and which one is about to hit a rate limit, abtop is the dashboard you wanted. The multi-agent workflow is now mainstream -- in 2026, the real question is how to run multiple agents together without everything collapsing into chaos. With subagent workflows, each agent team run burns through limits faster because you are running multiple context windows in parallel. Without a unified view, you're flying blind.
In identical benchmark tasks, Claude Code used 4x more tokens than Codex. Token costs accumulate with heavy autonomous use, so tracking usage matters. abtop puts that tracking directly in your terminal, with no external service required.
What it actually shows you
See every Claude Code, Codex CLI, and OpenCode session at a glance -- token usage, context window %, rate limits, child processes, open ports, and more. The dashboard is organized around the problems you actually hit when running agents in parallel:
