Xanadu
In daily useAn autonomous development loop: local LLMs plan, write, test and fix code straight from a roadmap, escalating to Claude only when they're stuck.
Xanadu is the engine behind everything else on this page. Give it a project's ROADMAP.md and it works through the tasks unattended, one validated change at a time, then surfaces only the blockers that genuinely need a human. Most of the work runs on local models on hardware I already own; paid cloud models are the last rung of the ladder, not the first.
- Works straight from a project's ROADMAP.md: one task, one tested change
- Tiered model ladder: four local LLM tiers first, Claude only after repeat failures
- Real validation gates: static analysis plus per-task tests on every attempt
- Learns from its mistakes: repeated error patterns become permanent rules shared across machines
- Scales from one Mac to parallel workers to rented RunPod GPUs
- Fully resumable: all state lives in the roadmap and git, so it survives being killed mid-run
