OCP v3.5.0: Zero-Config LAN Sharing — Your Family Can Use Claude in 30 Seconds

dtzp555-max — Sat, 11 Apr 2026 00:20:49 +0000

The Problem

You're paying for Claude Pro/Max. Your family wants to use AI tools too. Do you:

Buy separate subscriptions for everyone? 💸
Share your login? (against ToS)
Set up a proxy... but make everyone configure API keys?

The Solution: OCP v3.5.0

OCP (Open Claude Proxy) turns your Claude subscription into a standard OpenAI-compatible API. v3.5.0 makes sharing effortless:

Zero-Config for Everyone

Before (v3.4): Admin creates keys → shares keys → each person configures env vars → hope they don't mess it up.

Now (v3.5): Family member runs one command. Done.

curl -fsSL https://raw.githubusercontent.com/dtzp555-max/ocp/main/ocp-connect | bash -s -- 192.168.1.100

No keys. No Node.js. No repo clone. Just curl + python3 (already on every Mac/Linux).

How It Works

Wife's laptop   ──┐
Son's iPad      ───┼──→ OCP (your Mac mini) ──→ Claude subscription
Your Pi server  ───┤
Your desktop    ──┘

Server (one-time, on an always-on device):

git clone https://github.com/dtzp555-max/ocp.git && cd ocp
node setup.mjs --bind 0.0.0.0

Each client (30 seconds):

curl -fsSL .../ocp-connect | bash -s -- <server-ip>
source ~/.bashrc
# Done. Claude works in any IDE now.

Optional: Per-User Tracking

Want to see who's using how much? Keys are optional — create them when you want tracking:

ocp keys add wife-laptop
ocp keys add son-ipad
ocp usage --by-key

Or just check the web dashboard at http://<server-ip>:3456/dashboard.

What Else is New

Localhost = admin — no token needed on the server machine
Dashboard URL auth — share ?token=xxx links directly
authMode in /health — clients can detect auth requirements programmatically

Works With Everything

Any tool that speaks OpenAI protocol: Cline, OpenCode, Aider, Continue.dev, OpenClaw, and more.

$0 extra cost. One subscription. Whole household.

OCP v3.4: Share Your Claude Pro/Max Subscription Over LAN — Zero Extra Cost

dtzp555-max — Fri, 10 Apr 2026 12:14:44 +0000

If you're paying $20/month for Claude Pro or Max and also spending money on API credits to power your dev tools, you're paying twice for the same thing.

OCP (Open Claude Proxy) fixes that. It runs a local server that speaks the OpenAI API protocol, backed by your existing Claude subscription — zero extra API cost.

The Core Idea

OCP translates standard OpenAI /v1/chat/completions requests into claude -p CLI calls. Any tool that respects OPENAI_BASE_URL just works — no patching, no forks, no special plugins.

Cline          ──┐
OpenCode       ───┤
Aider          ───┼──→ OCP :3456 ──→ Claude CLI ──→ Your subscription
Continue.dev   ───┤
Any OpenAI app ──┘

Quick Start

git clone https://github.com/dtzp555-max/ocp.git
cd ocp
node setup.mjs

The setup script verifies your Claude CLI, starts the proxy on port 3456, and installs auto-start (launchd on macOS, systemd on Linux). Then point your tool:

export OPENAI_BASE_URL=http://127.0.0.1:3456/v1

Verify it works:

curl http://127.0.0.1:3456/v1/models
# Returns: claude-opus-4-6, claude-sonnet-4-6, claude-haiku-4

That's it. Cline, Aider, OpenCode, Continue.dev — anything that accepts a custom OpenAI base URL just works.

What's New in v3.4.0: LAN Mode

The headline feature: share one Claude subscription with your whole household.

One machine runs OCP, everyone on the network connects. Your partner's laptop, your kid's iPad, your homelab Pi — all using the same subscription.

Wife's laptop   ──┐
Son's iPad      ───┼──→ OCP :3456 (your Mac) ──→ Claude subscription
Your Pi server  ───┤
Your desktop    ──┘

Three Auth Tiers

Pick the level that fits your situation:

Mode	How it works	Best for
`none`	Open access on your LAN	Solo homelab
`shared`	One API key for everyone	Trusted small group
`multi`	Individual keys per user, separate tracking	Family / team (recommended)

Setup LAN Mode

node setup.mjs --bind 0.0.0.0 --auth-mode multi

# Create keys for each person
ocp keys add wife-laptop
#  Key created for wife-laptop
#  API Key: ocp_xDYzOB9ZKYzn...

ocp keys add son-ipad

# Show your IP and ready-to-share instructions
ocp lan

Give each person their key and two settings:

export OPENAI_BASE_URL=http://192.168.1.100:3456/v1
export OPENAI_API_KEY=ocp_<their-key>

Per-Key Usage Tracking

Every request is logged with key, model, token counts, latency, and success. All stored in local SQLite — zero external dependencies (uses Node.js built-in node:sqlite).

ocp usage --by-key
#  Key              Reqs   OK  Err  Avg Time
#  wife-laptop         5    5    0      8.0s
#  son-ipad            3    3    0      6.2s

Web Dashboard

Real-time monitoring at http://<your-ip>:3456/dashboard — per-key usage, request history, system health. Dark theme, auto-refresh. No login needed.

Why This Matters

The standard path for AI coding tools: subscribe to Claude Pro for the chat UI, then separately buy API credits so your tools can call the API. Two billing lines for functionally the same model access.

OCP collapses them. One subscription, used both ways. LAN Mode scales it to your whole household.

What It Doesn't Do

Uses claude -p (the Claude CLI), so you need it installed and authenticated
Rate limits still enforced by Anthropic — this doesn't bypass your plan's limits
Local proxy only, not a hosted service

Security

Localhost by default, LAN access is opt-in (CLAUDE_BIND=0.0.0.0)
Timing-safe key comparison for all auth modes
Keys stored locally in SQLite, never sent externally
Dashboard and health check are always public; everything else respects your auth config

If you're already paying for Claude Pro and buying separate API credits for your dev tools, give OCP a try. Setup takes five minutes.

OCP: Turn Your Claude Pro Subscription Into a Local OpenAI-Compatible API (Now With LAN Sharing)

OCP: Use your Claude Pro/Max subscription to power Cline, OpenCode, Aider, and any OpenAI-compatible IDE

dtzp555-max — Tue, 24 Mar 2026 07:54:03 +0000

If you're paying for Claude Pro ($20/mo) or Max ($100-200/mo), you already have access to Opus, Sonnet, and Haiku. Why pay again for API access in your dev tools?

OCP (Open Claude Proxy) turns your subscription into a standard OpenAI-compatible API on localhost. Any tool that speaks the OpenAI protocol just works:

Cline          ──┐
OpenCode       ───┤
Aider          ───┼──→ OCP :3456 ──→ Claude CLI ──→ Your subscription
Continue.dev   ───┤
OpenClaw       ───┘

Setup (60 seconds)

git clone https://github.com/dtzp555-max/ocp.git
cd ocp && node setup.mjs

Then in your IDE:

OPENAI_BASE_URL=http://127.0.0.1:3456/v1

That's it. Your IDE thinks it's talking to OpenAI. Claude CLI handles auth through your existing subscription.

Built-in Usage Monitoring

ocp usage shows your session/weekly utilization without opening the browser:

Plan Usage Limits
  Current session       21% used (resets in 3h 12m)
  Weekly (all models)   45% used (resets in 4d 2h)

Model Stats
  opus     5 reqs  avg 32s  avg 42K prompt
  sonnet  18 reqs  avg 20s  avg 36K prompt

What tools work?

Anything that accepts OPENAI_BASE_URL:

Cline — VS Code AI assistant
OpenCode — Terminal-based coding
Aider — AI pair programming
Continue.dev — IDE extension
OpenClaw — Multi-agent orchestration
Any OpenAI SDK client

I've been running 6 agents + 3 IDEs off a single Max subscription simultaneously for weeks. Zero API cost.

Key features

Zero dependencies — single Node.js file, no npm install
8 concurrent requests — multiple tools share one subscription
Real-time monitoring — ocp usage, ocp health, ocp settings
Runtime tuning — change timeouts, concurrency, prompt limits without restart
Auto-start — launchd (macOS) / systemd (Linux)
Prompt guard — auto-truncates runaway context at 150K chars

Stable v3.0.0. Works on macOS, Linux, and Raspberry Pi.
