LM Studio alternatives: 5 apps for running AI on your own computer

LM Studio is one of the best-known ways to run a language model on your own computer. It has a model browser, a chat window, a built-in local server and a command-line tool. It is free for personal and work use. So why look for an alternative?

Usually for one of four reasons: the app isn't open source, you want something simpler, you want the same assistant on a phone, or you want a lighter, developer-first tool. This guide covers five alternatives and when LM Studio is still the better choice. We make Loci, one of the five, so we flag it as ours and hold it to the same standard.

What LM Studio does well

• A strong GUI for finding and loading models. You can search Hugging Face, pick a download variant, and adjust settings from the app.
• A developer toolkit. It provides OpenAI-compatible endpoints, SDKs and a lms command-line tool. lms server start starts the server on http://localhost:1234 by default.
• A headless option. llmster runs LM Studio's engine without the desktop app, for servers.
• Free for home and work. LM Studio says you don't need a commercial license for workplace use.
• Runs on Mac (Apple silicon), Windows and Linux, plus an iPhone and iPad app (Locally) that connects to models on your computer.

If you like to tinker, benchmark quantizations or run a local API for your own code, LM Studio is the stronger tool and you should probably stay.

Why people look for an LM Studio alternative

1. It's closed source. LM Studio's terms describe a proprietary desktop app that you may not redistribute, sublicense, sell or host for others. If you need open-source tooling, that rules it out.
2. It's more than some people want. A model catalogue with variants, load settings and server options is powerful, but it's a lot if you just want to ask a question.
3. They want a phone app that runs models on the phone. LM Studio's phone app, Locally, connects back to your computer through LM Link, which requires an LM Studio account.
4. They want built-in web search and voice without add-ons. In LM Studio, web search comes through community plugins or MCP servers, and local voice transcription is in the separate Bionic app.
5. They want a server-first tool with a smaller footprint.

The five alternatives

1. Ollama: the developer's choice

Ollama is a command-line-first tool that runs a local server and works with a large library of models. The core project is MIT-licensed, it supports Linux, and nearly every open-source AI tool can connect to it. Local use is free; optional cloud plans start at $20 a month. Better than LM Studio at: scripting, servers, Linux, being the default integration target. Trade-offs: fewer GUI features; no phone app; web search needs an Ollama account.

2. Jan: open-source desktop chat

Jan is an open-source (Apache 2.0, with an added attribution request) desktop app for Windows, macOS and Linux. It runs models with an embedded llama.cpp engine, offers an OpenAI-compatible server at localhost:1337, supports MCP, and can also use cloud models with your own keys. Local models need Apple silicon on Mac. Better than LM Studio at: being open source; having one chat app that mixes local and cloud models. Trade-offs: desktop only; the project moves fast, so check the changelog.

3. GPT4All: MIT-licensed, document-first

GPT4All (Nomic) is a free MIT-licensed desktop app for Windows, macOS and Ubuntu. Its LocalDocs feature indexes folders of text, PDF and Markdown files so models can answer questions about them without sending files anywhere. Better than LM Studio at: document chat with very little setup; being open source. Trade-offs: its latest release when we checked was v3.10.0, from February 2025 ; confirm it supports the model families you want. No phone app.

4. AnythingLLM: workspaces and agents

AnythingLLM organises documents into workspaces and adds agent skills; it has desktop apps and an Android app that pairs with the desktop. Better than LM Studio at: structured document work. Trade-offs: more moving parts.

5. Loci: one app on every device (ours)

Loci is a free assistant with no account, no ads and no subscription. It runs open models such as Gemma and Qwen on Mac (Apple silicon; the direct download needs macOS 26.2 or later), Windows 11, iPhone, iPad and Android, and picks a model that fits your device on first launch. Web search, pictures, files, on-device dictation and spoken answers are built in, and Loci Link lets a phone use the models on your Mac or PC without an account. Better than LM Studio at: being finished and simple, including on a phone; no plugins for web search. Trade-offs: Mac and Windows builds are in beta; there's no Linux version; you have less direct control over model settings than in LM Studio. For developers, Loci exposes a loopback MCP server and an OpenAI-compatible endpoint while the app is open, but LM Studio's SDKs, CLI and headless mode go much further.

FAQ

What is the best free alternative to LM Studio?

Jan and GPT4All are open-source desktop apps, Ollama is a developer-focused tool, and Loci is a free assistant that also runs on phones. LM Studio itself is also free for personal and work use, so "free" alone is rarely the reason to switch.

Is there an open-source alternative to LM Studio?

Yes: Jan (Apache 2.0 with an attribution request), GPT4All (MIT) and Ollama's core (MIT). LM Studio's desktop app is proprietary.

Is LM Studio free for commercial use?

LM Studio says it is free for use at work, with no commercial license needed. Its terms still prohibit redistribution and hosting it as a service.

Which LM Studio alternative works on iPhone or Android?

Loci runs models on iPhone, iPad and Android. Locally, LM Studio's own app, connects to your computer. AnythingLLM has an Android app that pairs with its desktop app. PocketPal is an open-source phone app that runs small models on the phone.

Is there a private AI app for iPhone that works offline?

Yes. Loci runs the model on the iPhone, and typed chat works after the download with no connection and no account. LM Studio's phone app connects back to a computer.

Does LM Studio work offline?

Yes. After you download a model, local chat works without internet. Model search and downloads need a connection. The same is true of the alternatives above.

Can I use my LM Studio models in another app?

Most apps here import GGUF files. Check where LM Studio stores your models and whether the other app can import them from that folder.
