  • Self-hosting takes setup effort
  • AGPL license can deter commercial use
  • Smaller team than big assistants
  • Cloud tier needed for zero-setup use

Leon

  • Open source (MIT), free
  • Runs fully self-hosted
  • Local model + context support
  • Tools, memory, agentic modes
  • Mid-rewrite to 2.0 (preview)
  • Setup/maintenance burden
  • Small project vs big assistants
