This guide compares the top self-hosted LLM tools across performance, ease of use, scalability, hardware needs, and extensibility. This guide does not attempt to compare the various front-end user interfaces (UIs) such as Open WebUI and LibreChat, but does reference them, indicating that some LLMs may lack a friendly UI and you may want to consider installing one.
