The self-hosted AI gateway for Claude Code & Cursor

Yes. kRouter is MIT-licensed, open-source and self-hosted, and it never charges you anything. You pay only the AI providers you connect, and several have free tiers or free accounts (Kiro, OpenCode Free, OpenRouter, NVIDIA NIM and the Gemini API among them). Each provider sets its own limits.

kRouter is a self-hosted multimodal AI gateway. It exposes one local OpenAI-compatible endpoint (http://localhost:20128/v1) that routes chat, text-to-speech, speech-to-text, image generation, embeddings, web search and web fetch across 95+ providers, plus video through xAI. A plain "LLM router" only switches between chat models; kRouter puts every modality behind a single base URL.

Point Claude Code at kRouter's local endpoint, then connect a backend that serves Claude models, such as Kiro or a GitHub Copilot subscription you already have. A fallback combo tries your models in order, so you can put a free tier first, a cheap pay-per-token model next, and a paid key last.

20–40% fewer input tokens per request out of the box, from RTK, the only token saver that is on by default. The others are optional and off until you enable them: Caveman and Ponytail shorten replies, Headroom compresses repeated context through a separate Python proxy, and PXPIPE renders very large Claude context as images. What the optional savers save depends heavily on the workload.

kRouter is not a hosted service: it runs on your own machine or server, and requests go from there to the providers you connect. Each provider still sees what you send it. If you want less to reach them, turn on PII redaction (a Presidio sidecar, off by default), which removes names, emails, phone numbers and API keys from chat requests before they leave.

Any OpenAI-compatible client. The dashboard sets up Claude Code, Codex, OpenCode, Cline, Kilo Code, Factory Droid, OpenClaw and others for you, and has guides for Cursor (which needs a tunnel or cloud endpoint, not localhost), Roo, Continue and Amp. Antigravity, GitHub Copilot, Kiro and Claude Desktop have no endpoint setting, so kRouter routes them through local MITM interception. Requests are translated between the OpenAI, Anthropic and Gemini formats automatically.

Yes. Run kRouter on a VPS behind Nginx or Caddy, or expose it with Cloudflare Tunnel or Tailscale, and give each teammate a kRouter API key: callers on other machines always need one. Kiro can also connect with a long-lived API key (ksk_) instead of a browser login, which suits a headless server.

Run "npm install -g @sifxprime/krouter" and then "krouter -t" (Node.js 20.9 or newer), open the dashboard at http://localhost:20128/dashboard, connect a provider, and point your tool at http://localhost:20128/v1. Docker and source installs are also supported.
