carbon vs semble

carbon: Carbon is an open-source operating system designed for manufacturing, built to address the limitations of traditional ERP and MES solutions. It provides a modern, API-first approach, aiming to reduce vendor lock-in and offer a flexible, extensible platform for companies to build tailored applications.; 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.
