Our recommendation

Pick LocalAI when you want a drop-in OpenAI-compatible API you can run without a GPU — it serves LLM, image, and voice models on ordinary CPU hardware, so existing OpenAI-SDK code points at your server with just a URL change. It's the most API-compatible backend here (4 GB). It's a runtime, not a chat app: pair it with a UI, or call it from your own code. If you only ever run text models and want the leanest setup, Ollama is simpler.

What you need

  • Any VPS with at least 4096 MB of RAM
  • A domain you control — most self-hosted setups need HTTPS in front of them
  • Under an hour if you've used Docker before

Install

Run these commands on your server:

# LocalAI — official CPU-only container
docker run -p 8080:8080 --name local-ai -ti localai/localai:latest-cpu  #  →  http://SERVER_IP:8080

What you take on

LocalAI's OpenAI-compatibility is genuinely useful, but "runs without a GPU" comes with the usual asterisks:

non-negotiableNo GPU means slow. CPU inference works and is the selling point, but larger models will crawl — add an NVIDIA/AMD/Intel GPU when responsiveness matters, the same as every local-inference tool here.
non-negotiableIt's a backend, not a UI. LocalAI exposes an API; pair it with Open WebUI or LibreChat, or drive it from code — there's no chat window in the box.
non-negotiableCompatibility isn't identity. It mirrors the OpenAI API surface, but output quality depends on the open models you load — don't expect GPT-4-class answers from a small local model just because the API shape matches.
