What AI agent frameworks are you using and what's missing?

I'm building Promethios. A platform where any open-source AI agent framework (OpenClaw, Hermes, LangChain, etc.) can be onboarded, run in a sandbox, and shared with the community. Think of it as the App Store for AI agents.

Before we open the beta, I want to hear from the community: What frameworks are you actually running? What's the biggest pain point? Setup complexity, no community around it, can't share your agents, something else?

I'm reading every reply. This is genuinely shaping what we build next.
