semble vs revula
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.; revula: Revula is a production-grade MCP server that orchestrates a complete reverse engineering backend, enabling Claude Desktop, MCP-compatible IDEs, and custom tooling to access a wide range of RE tools through the Model Context Protocol. It supports static, dynamic, Android, firmware, malware analysis, and more with graceful degradation when external tools are missing.
01
TL;DR
Choose semble if…Enhancing AI agents (e.g., Claude Code, Cursor, Codex) with fast and accurate code search capabilities
Choose revula if…Malware triage and analysis (hash, IoC extraction, YARA scanning)
