LM Studio
the best desktop experience here, and unambiguously proprietary software wrapped around open engines.
genuinely the most refined tool in the category and the clearest example of its central problem — it appears in every 'best open source local llm tool' list and is not open source.
the product case is strong. it bundles both llama.cpp and apple's mlx runtime, so on apple silicon you get native mlx rather than a port, and it configures hardware-aware settings automatically instead of making you guess at layer offloads. gguf and mlx formats, cuda, metal, vulkan and rocm, and an openai-compatible server.
the licence is a flat contradiction of its reputation. element labs' terms grant free use 'solely for your personal and/or internal business purposes', prohibit resale, redistribution and offering it as a service to third parties, and forbid integrating anything that would oblige the app's own code to be opened. it is closed software that wraps open engines.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

genuinely the most refined tool in the category and the clearest example of its central problem — it appears in every 'best open source local llm tool' list and is not open source.
we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
