Selectools
Selectools is an open-source Python framework for building production-ready AI agents without a DSL or paid SaaS. A single 'pip install' unlocks tool calling, hybrid RAG, multi-agent orchestration via AgentGraph, and 50 built-in evaluators that replace paid services like LangSmith. It speaks nine providers—OpenAI, Anthropic, Gemini, Ollama, and 100+ models through LiteLLM—with router, fallback, and local providers, and serves agents as REST APIs or a browser-based visual builder in one line. Apache-2.0 licensed and API-stable at 1.0, it targets developers who want the full agent stack (guardrails, audit logging, observability) in plain Python with no vendor lock-in. It matters now as teams move from brittle chatbots to governed, testable agent workflows.
