Run Claude Code, Cursor, and Codex on any model via one proxy
Lynkr is an HTTP proxy that lets you point Claude Code, Cursor, and Codex at Ollama, Bedrock, or OpenRouter instead of Anthropic—zero client changes required.

What it does
Lynkr runs a local HTTP server that impersonates the Anthropic API. Point Claude Code, Cursor, or the Codex CLI at localhost:8081 and the proxy forwards requests to a backend of your choice—whether that’s a free local Ollama instance, AWS Bedrock, Databricks, or OpenRouter. The client tools need no code changes; you override a base URL and supply a dummy API key.
The interesting bit
The tier-routing feature classifies each request as simple, medium, complex, or reasoning, then dispatches it to a different model. The README claims this pushes 70–90% of traffic toward cheaper or local models while reserving expensive ones for genuinely hard tasks. It is a pragmatic admission that not every autocomplete needs a frontier model.
Key highlights
- Supports 12+ providers, including 4 local options (Ollama, llama.cpp, LM Studio) for fully offline use
- Drop-in compatibility: override
ANTHROPIC_BASE_URLfor Claude Code, or set a model provider override in Cursor and Codex configs - Built-in token optimizations (prompt caching, semantic caching) and load shedding under memory pressure
- 699 tests passing, Apache 2.0 licensed
- Enterprise-friendly routing to Databricks, Azure OpenAI, and AWS Bedrock
Caveats
- Getting Claude Code and Cursor to play nice requires explicit compatibility shims: you must cap
POLICY_MAX_STEPSandPOLICY_MAX_TOOL_CALLSand disablePOLICY_SAFE_COMMANDS_ENABLED, suggesting the proxy has to massage Anthropic-specific behavior that other models don’t natively support - The README dedicates an entire section to common startup errors, including missing tier warnings, fallback credential complaints, and a
pino-prettytransport bug in older versions—so expect some initial friction
Verdict
Worth a look if your team loves Claude Code’s UX but needs to run local models, hit a company-mandated Bedrock or Databricks endpoint, or slash API spend. Skip it if you’re already content with Anthropic’s native pricing and performance.
