Ollama vs Open WebUI
Ollama scores 99 to Open WebUI's 98 on public evidence for run LLMs locally, and they rank #1 and #2 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Ollama
One-command local LLM runner with a model library and an OpenAI-compatible API.
+ `ollama run llama3` is the simplest path to a local model, and most tools integrate with it.
− Hides llama.cpp tuning options, so throughput trails hand-tuned setups.
Open WebUI
Self-hosted ChatGPT-style web interface for Ollama and OpenAI-compatible backends.
+ Multi-user accounts, RAG, and tool plugins make it a full private ChatGPT replacement.
− Docker-only deployment and a licence change in 2025 that restricts branding removal.
