agentor vs semble
agentor: Agentor is the fastest way to build and deploy long-running AI agents with durability, observability, and security. It provides features like MCP & tool security, agent-to-agent communication, serverless deployment, observability, and tool search API. With a simple Python API, you can build agents, connect tools, and serve them as APIs or deploy with Celesto.; 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.
