semble vs skalex

semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.; skalex: Skalex is a zero-dependency, isomorphic, local-first JavaScript database with built-in vector search, agent memory, NLP queries, MCP server, and encryption. It runs on Node.js, Bun, Deno, browsers, and edge runtimes, supporting multiple storage backends and AI adapters. All AI capabilities are built into the core with no additional dependencies.
