CrabAgent - AI Agent Platform with dual-mode (CLI + Serve)

🦀 CrabAgent

AI Team Command Center — Build a team of specialized AI agents that learn and improve over time. Delegate, parallelize, and watch them work in real-time from terminal or browser.

CrabAgent is a local-first AI agent platform. Run it from any project directory via CLI, browser, or native macOS desktop app. Your data stays local, your API keys are encrypted, and you pick any LLM provider.

Why CrabAgent

Unlike other agent platforms where agents are "temporary workers who forget everything," CrabAgent's agents learn and evolve:

Capability	What it means
🧠 Self-Evolving Agents	Agents auto-extract lessons from every task — rule engine catches patterns, LLM reflection analyzes strategies. The more you use them, the smarter they get.
🤖 AI Team	Custom agent profiles with per-agent tool whitelists and model overrides. Delegate, parallelize, or run multi-step pipelines.
📊 Agent Growth Tracking	View each agent's stats: task count, success rate, lessons learned, common task categories. ctrl+space agent_stats
⏱ Scheduled + Real-time	Agents run on cron schedules or react to @mentions. Real-time streaming of every agent's output.
🦀 Snapshots	Auto-snapshot files before changes. Roll back anytime without Git.
🖥️ Desktop App	Native macOS app via Electron. Auto-starts backend, auto-login, same UI as browser.
🔒 Local-first	All data stays on your machine. API keys encrypted at rest. No telemetry.

Quick Start

pip install 'crabagent[serve]'

crabagent init

# TUI — interactive REPL with slash commands
crabagent

# TUI (legacy single-panel)
crabagent --old

# Web UI
crabagent --serve          # → http://localhost:5210
                           # Default login: admin / xcl1989

# Single-query CLI
crabagent "organize this directory"
crabagent -p deepseek -m deepseek-chat "write a Python script"

Desktop App (macOS)

# Build from source:
cd electron && npm install && npm run build:mac
# → electron/dist-electron/CrabAgent-0.9.0-arm64.dmg

Double-click CrabAgent.app — it auto-starts the Python backend, logs in, and opens the full Web UI in a native window. Requires Python 3.12+ with crabagent[serve] installed.
