LobeChat
Chat & assistant UIsA polished open-source chat UI with a plugin system, custom agents, and broad multi-model support.
LobeChat is a design-led open-source chat interface. It supports many model providers, adds a marketplace of plugins and prebuilt assistant personas, and handles voice and vision where models allow.
Its strength is polish: of the self-hosted chat front-ends, it is one of the most refined out of the box, which matters when the assistant faces non-technical staff.
Where it's ideally used
A good choice when presentation matters and you want a self-hosted assistant that feels like a finished consumer product.
Where it doesn't fit
The plugin-and-persona surface is more than you need for a stripped-down internal tool with one fixed job.
