Agentop

A terminal UI tool for monitoring local AI coding agents — like nvtop/htop, but for Claude/Codex.

Features

• Real-time process monitoring (CPU, memory, uptime)
• Claude Code usage + cost from local stats
• Quota panels (beta) for Codex + Antigravity
• Lightweight Textual TUI

Supported Agents

Supported Platforms (has been tested)

• macOS
• Linux

Installation (macOS / Linux)

PyPI

pip install agentop

From source

pip install git+https://github.com/dadwadw233/agentop.git

Quick Start

# TUI
agentop

# Or
python3 -m agentop

Detailed stats:

python3 show_stats.py

Data Sources

• Claude stats: JSONL logs under ~/.config/claude/projects/ or ~/.claude/projects/ (override with CLAUDE_CONFIG_DIR, supports comma-separated paths)
• Codex token usage: local session logs under ~/.codex/sessions/
• Codex quota: /usage API via Codex auth (~/.codex/auth.json)
• Antigravity quota: Google Cloud Code API via Antigravity auth (local state db)
• OpenCode stats: ~/.local/share/opencode/storage/ (message + session directories)

Changelog

0.2.0 (2026-01-25)

OpenCode Features:

• Fixed time filtering bug - now shows all historical data (not just today)
• Added time range support (Today/Week/Month/All) for all views
• Implemented lazy loading - only computes aggregates needed for current view
• Added index cache for faster incremental parsing
• Performance optimizations for large datasets

TUI Improvements:

• Redesigned overview dashboard with structured layout (Process Status, Session Stats, Token Usage)
• Added progress bars for visual token usage comparison
• Implemented pagination for handling large datasets
• Dynamic page sizing based on available screen height
• Enhanced table formatting with better alignment and smart truncation
• Color gradients for usage intensity (cyan/magenta/blue)
• Visual status indicators (🟢/⚪) with colored borders
• Improved hint text with time range display and update timestamps
• Consistent styling across all sub-views (Sessions, Projects, Models, Agents, Timeline)

Roadmap

• More agents (TBD)
• Config file (YAML)
• History + export (CSV/JSON)
• UI polish

Known Limitations

• Claude stats can lag behind real time
• Codex local token stats depend on availability of token_count events in session logs
• Antigravity quota depends on account access
• Antigravity refresh requires ANTIGRAVITY_OAUTH_CLIENT_SECRET or a fresh login
• Proxy users: if you see “unknown scheme for proxy URL”, set AGENTOP_DISABLE_PROXY=1 or install httpx[socks]
