LM Studio is the most widely used desktop app for running open-weight language models locally. Free for personal and work use, it offers a GGUF and MLX model browser, built-in chat UI, and a local OpenAI-compatible API server across Mac, Windows, and Linux.

llama.cpp is the open-source C++ inference engine that powers Ollama, LM Studio, and most local LLM tooling. Created by Georgi Gerganov in 2023, it runs 50+ model architectures on any hardware, including consumer laptops and Raspberry Pis.

Open WebUI is a free, self-hosted interface for running local LLMs. It connects to Ollama and any OpenAI-compatible backend, adds a polished chat UI, document RAG, voice input, multi-user access controls, and enterprise SSO, all without data leaving your server.

LocalAI is a free, open-source AI engine by Ettore Di Giacinto that runs any model locally with a drop-in OpenAI-compatible API. No cloud, no GPU required, and no data leaves your hardware.

MLX is Apple ML Research's open-source array framework for running and fine-tuning machine learning models on Apple Silicon. Free, MIT-licensed, and designed to extract maximum performance from M1 through M5 chips using unified memory.

Cherry Studio is a free, open-source desktop client that unifies 300+ LLM providers including OpenAI, Claude, Gemini, and local Ollama models in a single interface. It adds built-in RAG knowledge bases, MCP agent support, and side-by-side model comparison on Windows, macOS, and Linux.

Pinokio is a free desktop app by cocktailpeanut that turns installing open-source AI tools into a one-click operation. It manages all Python environments, dependencies, and GPU setup automatically, making ComfyUI, Whisper, Bark, and hundreds of other AI apps accessible to anyone without terminal experience.

Gemma is Google DeepMind's family of open-weight language models, downloadable and self-hostable for free. Gemma 4 (April 2026) delivers frontier-level reasoning and multimodal capabilities under an Apache 2.0 license, from 2B edge models to a 31B dense flagship.

vLLM is an open-source LLM inference library from UC Berkeley that delivers high-throughput, memory-efficient serving for hundreds of open models. Free under Apache 2.0, with an OpenAI-compatible API and support for multi-GPU deployments.

Microsoft's Phi family proves data quality beats scale. The Phi-4 generation (14B, MIT license) punches above its weight on math and reasoning, and runs on consumer hardware. Free to download, with paid hosted inference on Azure AI Foundry.
