Ornn vs nix-ai

Ornn: Ornn is an agent-facing skill lifecycle API — the npm registry and CLI fused into one, but for AI agent skills. Agents call Ornn directly over HTTP or MCP to search, pull, install, execute, build, upload, and share skills. It is model-agnostic, working with Claude, GPT, Gemini, or any custom runtime. Designed for agentic-system builders who want to manage reusable skills programmatically rather than hardcoding capabilities into each agent.; nix-ai: nix-ai is a declarative AI coding toolkit that uses Nix to capture and manage your entire AI development setup as code. It ensures that your configurations for various AI tools like Claude Code, Gemini, Copilot, and local MLX inference are reproducible across different machines with a single command.
