Captain Memo is a local shared memory system that enables multiple coding assistants (Claude Code, Codex, Gemini, Cursor, and others) to read and write to a unified knowledge base via MCP. It automatically captures coding sessions, indexes learnings into searchable embeddings, and injects relevant context into prompts while keeping all data on disk with no cloud dependency.
Yac is a WordPress object cache extension that stores data in shared memory accessible to all PHP workers, eliminating the need for a separate cache server. It achieves ~19% faster page renders than Memcached by removing socket and network overhead, with no external infrastructure to operate or maintain.
