ClawSnap TeamMarch 20, 20262 min read

ClawSnap offers two production-ready agent types: ZeroClaw and OpenClaw. Both run on dedicated VMs with full root access, but they're built for different use cases. Here's how to choose.

ZeroClaw: The Lightweight Operator

ZeroClaw is a 30MB binary that starts in seconds. It's built for conversational AI, task execution, and channel management.

Best for:

  • Chat-first workflows
  • Telegram/Discord/Slack bots
  • Automations and cron jobs
  • Quick prototyping
  • Users who want a fast, focused agent

Key features:

  • WebSocket-based chat with streaming responses
  • Persistent memory (SOUL.md, workspace files)
  • Channel integrations (Telegram, Discord, WhatsApp, Slack, IRC)
  • Shell command execution
  • Cron scheduling
  • Lightweight — runs comfortably on the smallest VM

OpenClaw: The Full Runtime

OpenClaw is a complete agent ecosystem with 50+ installable skills, HTTP API endpoints, sub-agent orchestration, and browser automation.

Best for:

  • Complex workflows requiring multiple skills
  • API-driven integrations
  • Browser automation and web scraping
  • Teams needing sub-agent delegation
  • Power users who need everything

Key features:

  • 50+ installable skills (web search, email, calendar, code execution, etc.)
  • OpenAI-compatible HTTP API
  • Sub-agent orchestration
  • Browser automation via headless Chromium
  • Voice call capabilities
  • Persistent sessions with gateway token auth

Side-by-Side Comparison

| Feature | ZeroClaw | OpenClaw | |---------|----------|----------| | Binary size | 30MB | Full runtime | | Boot time | Seconds | 1-2 minutes | | Chat protocol | WebSocket | HTTP API + WebSocket | | Skills ecosystem | Manual | 50+ installable | | Channel support | Yes | Yes | | Browser automation | No | Yes | | Sub-agents | No | Yes | | Voice calls | No | Yes | | Resource usage | Low | Moderate | | Best for | Chat & automations | Complex workflows |

Our Recommendation

Start with ZeroClaw if you're new to ClawSnap or want a responsive chat agent for your messaging channels. It's fast, lightweight, and does 80% of what most users need.

Choose OpenClaw if you need the skills ecosystem, API endpoints, browser automation, or sub-agent orchestration. It's more resource-intensive but significantly more capable.

Both agents run on the same dedicated VM with full root access. You can always deploy one of each and use them for different tasks.
