semble vs fli

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.; fli: Fli is a powerful Python library and MCP server providing programmatic access to Google Flights data. It leverages reverse-engineered API access for fast, reliable, and modular flight searches, offering both a CLI and a Python API for comprehensive flight search, deal finding, and results filtering.
