Open Source LM Studio Alternatives
Desktop app for running local LLMs — LM Studio pricing: Free for personal use; commercial use requires a licence from the vendor. Below: 4 free,
self-hostable open source projects that cover the same ground, ranked by real GitHub adoption.
There are 4 open source LM Studio alternatives tracked on this registry, against LM Studio pricing of Free for personal use; commercial use requires a licence from the vendor. The most-adopted is Ollama with 181,290 GitHub stars under MIT, written in Go. Together the set has 432,124 stars across 3 languages and 1 licence. All 4 are free to self-host with no licence fee, and 3 of 4 received a commit in the last 90 days. 4 head-to-head LM Studio comparisons are available.
LM Studio makes local inference easy but its licence is not open: commercial use requires a paid agreement with the vendor, and the application itself is closed source. It targets desktop use, so headless servers and containerised deployments are not its design centre.
Our top 3 LM Studio alternatives
Ollama is a command-line tool and local server that manages open-weight language models on the machine it runs on. It ships a CLI, a REST API on port 11434, and client libraries for Python and JavaScript, so the same model can be driven from a terminal, a script, or an existing agent framework. Model execution is handled by the llama.cpp backend, and the project distributes installers for macOS, Windows and Linux alongside an official `ollama/ollama` Docker image.

llama.cpp is a C/C++ library and set of command-line tools for running large language models (LLMs) and vision-language models (VLMs) locally. It enables inference without external dependencies, targeting diverse hardware including Apple Silicon, x86 CPUs, NVIDIA GPUs (via CUDA), AMD GPUs (via HIP), and other accelerators. The project lives in the ggml ecosystem, leveraging the ggml tensor computation library for low-level operations and quantized model execution.

GPT4All is an open-source application for running large language models locally. It ships as native installers for Windows, Windows ARM, macOS, and Ubuntu, with a community-maintained Flathub package, and it also provides a Python client that wraps llama.cpp implementations under the package name gpt4all. Models are distributed in the GGUF format; the README's own example loads Meta-Llama-3-8B-Instruct.Q4_0.gguf, and the project advertises support for DeepSeek R1 distillations. The codebase is written in C++, licensed MIT, and described as open-source and available for commercial use.
