+title: "Strix Router"
+description: "Access top LLMs through a single API with high rate limits and zero data retention"
+---
+
+Strix Router gives you access to the best LLMs through a single API key.
+
+<Note>
+Strix Router is currently in **beta**. It's completely optional — Strix works with any [LiteLLM-compatible provider](/llm-providers/overview) using your own API keys, or with [local models](/llm-providers/local). Strix Router is just the setup we test and optimize for.
+</Note>
+
+## Why Use Strix Router?
+
+- **High rate limits** — No throttling during long-running scans
+- **Zero data retention** — Routes to providers with zero data retention policies enabled
+- **Failover & load balancing** — Automatic fallback across providers for reliability
+- **Simple setup** — One API key, one environment variable, no provider accounts needed
+- **No markup** — Same token pricing as the underlying providers, no extra fees
+- **$10 free credit** — Try it free on signup, no credit card required
+
+## Quick Start
+
+1. Get your API key at [models.strix.ai](https://models.strix.ai)
+2. Set your environment:
+
+```bash
+export LLM_API_KEY='your-strix-api-key'
+export STRIX_LLM='strix/claude-sonnet-4.6'
+```
+
+3. Run a scan:
+
+```bash
+strix --target ./your-app
+```
