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

Yes, completely. RelayPlane is free and open source (MIT). Every feature is included: full proxy, local and cloud dashboard, all 11 providers, budget enforcement, anomaly detection, hard cost caps, auto-kill, and 90-day history. It runs locally on your machine, your keys and prompts never leave your box. No tiers, no paywalls, no credit card. See relayplane.com/pricing.

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.
