Locally Uncensored vs Jan
The short version: both apps are open source under AGPL-3.0, and both are good at what they aim for. Jan is the cleaner pure chat client — a local ChatGPT feel with a model hub and plugins. Locally Uncensored is the Jan alternative with image and video generation: chat plus FLUX images, Wan video, music, and a coding agent in one installer. Chat only? Jan is solid. More than chat? That is the whole point of Locally Uncensored.

When Jan Is the Better Choice
When you want exactly a chat app, done well. Jan is what most people picture when they say "open-source LM Studio": a clean, actively developed desktop client with a Hugging Face model browser, an extension system for community plugins, cloud API connections if you want them, and a bundled inference engine so nothing else needs to run. It also supports macOS, which Locally Uncensored currently does not. For chat plus plugins and nothing more, Jan is a genuinely solid pick.
When Locally Uncensored Wins
When chat is the start, not the end. Locally Uncensored covers the same ground — local chat, open source, one installer — and then keeps going: local image generation, video generation, a music lane, a coding agent with 14 tools, phone remote access, A/B model compare and a local benchmark, all in the same app. The Tauri shell stays lightweight next to Jan's Electron footprint, and abliterated, uncensored models are first-class in the catalog rather than a manual workaround.
The two even cooperate: Jan is one of the 12 backends the setup wizard auto-detects, so an existing Jan install can serve as a chat engine.

FAQ
Is Jan open source?
Yes. Jan is open source under AGPL-3.0 — the same license as Locally Uncensored. Both apps are fully auditable, and you can modify or self-host either one.
Does Jan generate images or video?
No. Jan is a chat-focused client: no image generation, no video generation, no coding agent. Locally Uncensored is the Jan alternative with image and video generation — FLUX 2, Juggernaut XL, Z-Image and SDXL images plus Wan, HunyuanVideo, LTX and FramePack video, all local.
Which app is better for pure text chat?
For chat alone, Jan is an excellent pick: a clean ChatGPT-like interface, a Hugging Face model browser, an extension system and a bundled inference engine. Locally Uncensored matches the chat basics and adds memory, personas, vision and thinking mode — but if you never need more than chat, Jan is a solid choice.
