LlamaIndex is offered as cloud / SaaS and hybrid, and a hybrid deployment usually means some components can run on your own infrastructure while the rest stays vendor-hosted. We have not confirmed a completely self-hosted option, so check with the vendor if that is a requirement.","source":"https://www.llamaindex.ai/pricing","question":"Can LlamaIndex be self-hosted?","confidence":0.6},{"answer":"We have confirmed 3 integrations for LlamaIndex, including AWS, Microsoft Azure and GitHub.
