Question 1

What is RelayPlane?

Accepted Answer

RelayPlane is an npm-native Node.js LLM proxy. Install with npm install @relayplane/proxy, point your ANTHROPIC_BASE_URL or OPENAI_BASE_URL at http://localhost:4100, and get per-request cost tracking, complexity-based model routing, and Ollama local fallback, no Docker required.

Question 2

How does RelayPlane compare to LiteLLM?

Accepted Answer

LiteLLM is a Python library with a proxy server option. RelayPlane is npm-native for Node.js developers, no Python, no Docker, just npm install. RelayPlane has per-request cost tracking built in and integrates directly with Claude Code, Cursor, and OpenClaw via a simple base URL override.

Question 3

How does RelayPlane compare to Portkey or Helicone?

Accepted Answer

Portkey and Helicone offer cloud observability and are npm-compatible. RelayPlane runs entirely locally (no cloud required), is open source under MIT, and focuses on cost tracking plus complexity-based routing for Node.js developers using Claude Code, Cursor, and OpenClaw.

Question 4

Does RelayPlane work with Claude Code and Cursor?

Accepted Answer

Yes. RelayPlane is designed for Claude Code, Cursor, and any tool that supports ANTHROPIC_BASE_URL or OPENAI_BASE_URL. Set ANTHROPIC_BASE_URL=http://localhost:4100 and RelayPlane intercepts every request, tracks costs, and routes to cheaper models for simple tasks.

Question 5

Is RelayPlane free?

Accepted Answer

The core RelayPlane proxy and local dashboard are free forever. Open source (MIT), runs locally on your machine, your keys and prompts never leave your box. Pro ($19/mo) adds network routing intelligence and 90-day history. Max ($99/mo) adds team coordination, audit logs, and approval gates. See relayplane.com/pricing for the full breakdown.

Question 6

How do I install the RelayPlane npm LLM proxy?

Accepted Answer

Run: npm install -g @relayplane/proxy. Then: relayplane init && relayplane start. The local dashboard runs at http://localhost:4100. Set ANTHROPIC_BASE_URL=http://localhost:4100 in your environment and all Claude requests route through RelayPlane automatically.
