Abtop Open source

What it does

Abtop is a terminal dashboard, styled after htop, purpose-built to monitor AI coding agent sessions rather than system processes. Instead of CPU/RAM per process, it shows per-session token usage, context-window percentage, rate limits, git status, running child processes, open ports, and current task, refreshed live while you work.

What is inside

This isn't a tool the agent calls — it's an operator-facing dashboard you run alongside your agent to watch what it's doing. Panels include: token/context usage, rate-limit countdowns, session status, child process/port trees, and git status, with 12 built-in color themes (including colorblind-friendly options).

Works with

• Claude Code — full support (token usage, context %, rate limits, tasks)
• Codex CLI — supported, minus context window %, current task, rate limit and memory status
• OpenCode — limited support, and requires a local sqlite3 database

How to install or connect

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

Also installable via cargo install abtop, a Windows PowerShell installer, or pre-built binaries from GitHub Releases. A 120x40 terminal is recommended (minimum 80x24).

Maintenance and safety

MIT licensed, written in Rust, with roughly 3.6k GitHub stars and active development. The README states it is "all read-only. No API keys. No auth," and doesn't transmit data over the network — though its JSON session snapshots can contain project context and should be handled as private. Because it never writes to your agent sessions or touches your source code, the main safety consideration is simply keeping any exported snapshot files private, the same way you would treat a screenshot of a terminal.

Who should use it

Anyone running multiple long-lived Claude Code, Codex or OpenCode sessions at once who wants a single always-on view of token burn, rate limits and session health instead of tabbing between terminals. It's a companion utility, not a coding agent itself — pair it with one of the tools it monitors, and expect the most complete picture when that tool is Claude Code.
