What each one is
The product in its own terms, so the numbers below have context.
Haystack
A Python-based orchestration framework for building production-ready AI applications with modular pipelines, agent workflows, and retrieval-augmented generation (RAG). Provides explicit control over retrieval, reasoning, memory, tools, and generation components, supporting everything from simple semantic search to complex multi-step agent systems.
Ollama
LeaderOllama enables developers to run open-source language models either on their own computers or through Ollama's cloud infrastructure, with a guarantee that user prompts and responses are never logged, stored, or used for training. Models can run locally without internet (limited by hardware) or in the cloud with no performance constraints.
