It's a split decision.
Choose Jan if you want a free, open-source Mac app for local models and chats with online providers using your own API keys. Choose LM Studio if you want local models plus an agent for coding and work, local voice transcription, or optional hosted open models. Jan has no paid tiers; LM Studio’s hosted features start at $20 per month, with a $100 Pro plan. Neither is documented here as a developer API or SDK.

02Pricing at real usage
Jan is free, with no paid tiers or annual price listed. Its free app includes unlimited local inference and model downloads. If you connect an online provider, you supply your own API key and that provider bills you directly; the amount depends on the provider and usage, not a Jan subscription.
LM Studio’s Free plan costs $0 per month for local LLMs with llama.cpp and MLX, LM Link for up to five devices, offline voice transcription and limited web search. Bionic+ costs $20 per month and adds US-hosted open-source models, discounted bulk tokens, web search and page extraction. Pro costs $100 per month and lists 5× usage limits, early feature access and the Bionic+ features. The pricing page gives monthly prices, not annual discounts. Organization plans offer pooled credits or team seats, but prices are not published.
03API, SDKs and integration
Jan is a desktop chat app, not a documented developer API. Its homepage lets users choose open models or connect online models from OpenAI, Anthropic, Google, Meta, Mistral, Alibaba, DeepSeek and Moonshot AI. Online connections use your API keys, with provider billing. Jan’s site links to docs, but the vendor doesn't publish developer API or SDK specifications, supported programming languages, or a CLI in its product pages.
LM Studio runs local models through its runtime, with MLX and llama.cpp under the hood. Bionic adds document editing, coding tasks, automation and computer control; its voice transcription processes audio locally. Optional cloud inference provides hosted open models, and LM Studio says its cloud services use Zero Data Retention. The site links to Bionic docs, but it doesn't describe a production API or SDK integration in its product pages. Developers should confirm supported interfaces and limits before building a service around either app.
04Open source, self-hosting and lock-in
Jan is open source under the Apache-2.0 licence, and its local inference runs on your computer. You can also connect online providers with your own API keys, so provider billing and access remain tied to those accounts. The vendor presents Jan as built in public.
LM Studio supports local inference through its runtime, MLX and llama.cpp, and is self-hostable in the sense that models run on your computer. The vendor doesn't publish an open-source licence for LM Studio, so don't assume the application itself can be modified or redistributed under an open licence. Its optional cloud services use Zero Data Retention, according to the homepage. Neither product page specifies a data-export format or migration path. For production, check how chats, model files and agent-created documents can be exported before relying on either app as a durable workflow layer.
