devduck vs semble
devduck: DevDuck is a self-modifying AI agent that hot-reloads its own code, adapting and expanding capabilities at runtime. It is a single Python file deployable anywhere—terminal, browser, cloud, or unified mesh—and supports multi-protocol servers, dynamic tools, and peer-to-peer networking.; 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.
