NadirClaw

NadirClaw

  The lowest viable model, verified.
  NadirClaw routes every prompt to the cheapest model that can reliably answer, verifies the
  output, and escalates only when it has to. Better answers at lower cost, and it prices every
  routed request against your baseline so you can see what it actually saved.

  NadirClaw is the source-available, self-hosted core of Nadir, the hosted LLM router built by the same team. It is licensed under PolyForm Noncommercial 1.0.0, so it is source-available, not open source.

Why NadirClaw?

Most LLM requests don't need a premium model. In typical coding sessions, 60-70% of prompts are simple — reading files, short questions, formatting. They can be handled by models that cost 10-20x less.

- Cut AI API costs — how much depends on your prompt mix, so NadirClaw measures it per request
- ~10ms classification overhead — you won't notice it
- Drop-in proxy — works with any OpenAI-compatible tool
- Runs locally — your API keys never leave your machine
- Fallback chains — automatic failover when models are down
- Built-in cost tracking — dashboard, reports, budget alerts
Your keys. Your models. No middleman. NadirClaw runs locally and routes directly to providers. No third-party proxy, no subsidized tokens, no platform that can pull the plug on you. Why this matters.
