CTX vs registry

Q: Which is better, CTX or registry?

By GitHub stars, CTX has more community adoption, but the best choice depends on your specific use case.

CTX: CTX is a local context runtime for OpenCode and AI coding agents. It reduces token waste by indexing repositories, storing reusable guidance as graph memory, and providing compact task packs, read-cache compression, command pruning, and a live right-sidebar dashboard. It integrates natively with OpenCode as a context layer without replacing the agent launcher.; registry: MCP Armory Registry provides production-ready MCP servers for popular APIs, generated from OpenAPI specs. Each server is a standalone Python package tested against live APIs. Hosted on MCP Armory or run independently.
