What is lemon?
Lemon is a self-hosted AI assistant for the terminal, browser, Telegram, and Discord. It brings model providers, coding tools, memory, skills, and scheduled tasks together in one runtime that the user controls. Sub-agents share the same execution stack, and work can be sent to other computers through named execution nodes. It also includes LemonSim, a simulation for observing and evaluating agent behavior. It is still a pre-1.0 version.

- Coding agent that works directly in your repository
- Parallel delegation to sub-agents (scout, reviewer)
- MCP tool connections
- Ongoing task tracking based on goals and a kanban board
- Dispatch work to other machines (execution nodes)
- LemonSim agent evaluation simulation
Who uses lemon and for what
