Rayline Local

Rayline Local is the open-source local router from Atlas Futures, Inc. It runs
on your machine and sits between your coding agent and the AI models it talks
to, deciding where each request should go. It provides the rayline CLI and
rld daemon for local passthrough, selective subagent routing, local model
support, and update checks.

This repository contains the Rayline Local router. Local-router-only use through
rayline claude --local does not require a hosted account and does not
connect to any remote hosted service.

Demo

Claude Code running with hybrid cloud + on-device AI. The main agent runs Opus
in the cloud and orchestrates an Explore subagent that Rayline Local routes to
a model running fully on your machine (Qwen3.6-35B-A3B, Q4) — seamlessly, in a
single session.

How It Works

Run rayline claude to start a Claude Code session with hosted Rayline routing
layered on top, or rayline claude --local for the auth-free local static
router. Your conversation works as it normally would, but Rayline Local can
route cheaper, high-volume work such as background subagent tasks to a fast
model running locally on your machine.

Routing is set by three orthogonal flags: --local picks the on-device router
(versus the hosted cloud router), --via proxy|env picks how Claude Code
connects, and --route all|subagents picks what flows through the router. Most
users only ever need --local. By default, your main conversation stays on
Claude, and only configured subagent traffic is routed to local or alternative
endpoints. See docs/rayline-local-router.md
for the full matrix. Run rayline --help to see the available commands and
configuration options.

Rayline Local operates on your machine and with your provider credentials. It is
not affiliated with any model provider.

Supported Clients

• Claude Code, Anthropic's CLI coding agent.

More clients may be supported over time.

Install

Rayline Local release assets are published on
GitHub Releases.

macOS and Linux:

curl -fsSL https://raw.githubusercontent.com/rayline-ai/rayline/main/scripts/install-rayline.sh | sh

Windows PowerShell:

irm https://raw.githubusercontent.com/rayline-ai/rayline/main/scripts/install-rayline.ps1 | iex

The installers place rayline and rld in ~/.rayline/bin by default and
verify downloaded binaries against the release SHA256SUMS file.

User Responsibility and Local TLS Interception

To route traffic in proxy modes, Rayline Local can install a local certificate
authority on your machine and intercept TLS traffic to provider APIs locally,
using your own credentials. You are responsible for ensuring your use of
Rayline Local complies with the terms of service of any provider whose API you
route to. Install and use Rayline Local only on machines and accounts you
control.
