---Which Framework Should You Choose?
"I want the smartest long-term investment" → Hermes Agent. The learning loop means it improves the longer you use it.
"I need the most integrations" → OpenClaw. 13,700+ skills, broadest messaging platform support.
"I need multiple agents working together" → CrewAI. Best multi-agent orchestration framework.
"I'm building custom AI pipelines" → LangChain/LangGraph. Maximum flexibility for developers.
"I just want to try agents" → Start with ChatGPT's built-in features. No setup required.
"I mostly write code" → Skip all of these. Use Claude Code or Cursor instead.

---Frequently Asked Questions
Can I switch frameworks later?
Yes. Hermes even ships a migration command from OpenClaw (hermes claw migrate). Skills built on the agentskills.io standard are portable across frameworks. Your LLM provider configuration transfers easily since most frameworks are model-agnostic.
Which framework is most reliable in production?
OpenClaw has the most production deployment experience (345K stars, 137+ releases). Hermes is newer but has conservative security defaults. Neither should run unsupervised in production without monitoring and human review for important actions.
