Alternatives to LM Studio
A polished desktop app for downloading, running and chatting with local language models, with an OpenAI-compatible server built in. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
LM Studio
A polished desktop app for downloading, running and chatting with local language models, with an OpenAI-compatible server built in.
Replacements
Listings that take over the same core job as LM Studio.
Ollama
The simplest way to pull down an open language model and run it on your own machine, from one command or a desktop app.
Ollama is MIT-licensed open source and runs models from one command or a desktop app with a localhost REST API, with a simpler interface than LM Studio.
Jan
An open-source ChatGPT replacement that runs entirely offline, and can also front cloud providers when you want them.
Jan is Apache 2.0 licensed and runs local models offline while also fronting cloud providers, though it is still pre-1.0 and changing between releases.
GPT4All
A local AI chat app with document chat built in, from Nomic AI. Stable, MIT licensed, but not updated since early 2025.
GPT4All is MIT-licensed open source with LocalDocs document chat and CPU operation, but its latest release dates from February 2025.
Msty
Desktop workspace for chatting with local and hosted AI models in one place.
Msty runs local and hosted models with prompt libraries and knowledge bases in one desktop app, and like LM Studio it is closed source with paid features.
AnythingLLM
A desktop AI app that answers questions about your own documents, with no account and no API key needed.
AnythingLLM is MIT-licensed and combines chat, a vector database and document pipeline in one install, focused on document questions rather than model browsing.
KoboldCpp
A single executable that runs GGUF language models locally, with a web interface and no installation at all.
KoboldCpp is an AGPL-licensed single executable with OpenAI-compatible endpoints plus image and speech features, but you find model files yourself and the interface is dense.
TextGen
Chat with local language models using the TextGen desktop interface.
TextGen is an open-source AGPL-3.0 desktop interface for local models with text, vision and API access in portable builds.
llama.cpp
The C++ engine most local AI apps are built on, running language models on ordinary hardware.
llama.cpp is the MIT-licensed engine LM Studio builds on, offering a built-in server and basic web interface but a command-line-first workflow.
Also worth comparing
These listings name LM Studio as their own alternative, so the relationship runs both ways.
