The honest brief

Jan

Bundles its own model runner so it works offline out of the box — no account, no telemetry, and no paid tier.

  • Local-first; data stays on your machine
  • Open source (Apache-2.0), no paid tier
  • Bundled model runner + model hub
  • BYO cloud keys when wanted
  • Local OpenAI-compatible server
  • More setup friction than LM Studio
  • Limited tool-calling vs full agent stacks
  • Local model speed bound by your hardware
  • Smaller ecosystem than Ollama

Ollama

The simplest one-command local LLM runner with a drop-in OpenAI-compatible server and broad model library.

  • One-command pull-and-run
  • Runs fully offline, no API key
  • Native macOS/Windows/Linux apps
  • MIT-licensed, free locally
  • Huge open-weight model library
  • Local performance bound by your hardware
  • Less tunable than vLLM for serving
  • Cloud tier needed for largest models
