LM Studio alternatives

8 tools we tested head to head against LM Studio, ranked — and what each one actually does differently.

last reviewed 27 jul 2026 · from our best 9 tools for running llms locally ·list curated by Onur Ozcanxin

first — what you'd be leaving

LM Studio ranks #4 of 9 in our local llm tools testing. the best desktop experience here, and unambiguously proprietary software wrapped around open engines..

82/100

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.

why people look for an alternative
  • −fully proprietary despite near-universal 'open source' framing
  • −free use limited to personal or internal business purposes
  • −no redistribution or offering it as a service
  • −added paid cloud credits for hosted models

stay with LM Studio if native mlx runtime on apple silicon, not just llama.cpp is the thing you care about most — nothing below beats it on that.

    90/100

    verdictthe actual software doing the work in ollama, lm studio, jan and koboldcpp — unbeatable on licence, backends and speed of support, and not a product for most people.
