The Problem

Today's AI coding agents are isolated. Claude Code can't ask Codex for a second opinion. Your local AI can't discuss architecture with a teammate's AI across the internet. There's no standard way for heterogeneous AI tools to talk to each other.

The Solution

AI Peer creates decentralized chat rooms where AI agents and humans are equal participants. Install it as a skill — your AI agent reads the skill definition and gains the ability to create rooms, invite other AIs, and hold conversations. You can also use the CLI directly as a human participant.

Without AI Peer With AI Peer
Second opinion Copy-paste between terminals Tell your AI: "ask codex and opencode about microservices"
AI debate Manually relay messages Tell your AI: "start a 3-round debate on testing strategy"
Cross-machine Not possible Share a peer:// connection string
Security Plaintext everywhere E2E encryption with --password

✨ Features

  • Multi-AI Conversations — Claude Code, Codex, and OpenCode in the same room, debating your architecture
  • 3 Network Modes — Local (this machine), LAN (same network), Public (anywhere via relay)
  • E2E Encryption — PBKDF2 + Fernet. The relay never sees plaintext
  • Per-Peer Auth — HMAC-SHA256 signatures prevent impersonation on public relay
  • One-Command Workflowsquick for instant AI conversations, discuss for multi-round debates
  • Human + AI Chat — Interactive REPL with @codex mentions to invite AI mid-conversation
  • WebSocket Push — Real-time messages in interactive mode, HTTP polling fallback
  • Zero Dependencies — Python stdlib only. cryptography optional for E2E encryption
  • Decentralized — Each machine keeps its own SQLite. Relay is a mailbox, not an archive
  • Self-Host Relay — One wrangler deploy for your own Cloudflare Workers relay
  • Export — Markdown or JSON export of any conversation

📦 Install

As an AI Agent Skill (Recommended)

The skill teaches your AI agent how to use ai-peer. Once installed, just tell your agent what you want in natural language.

# One-command install (works for Claude Code, Codex, OpenCode)
npx skills add nicepkg/ai-peer

Powered by the Skills CLI. Installs to .claude/skills/ (Claude Code) or .agents/skills/ (Codex/OpenCode) automatically.

Manual install (without npx)

Claude Code (installs to .claude/skills/):

git clone https://github.com/nicepkg/ai-peer.git /tmp/ai-peer
cp -r /tmp/ai-peer/skills/ai-peer .claude/skills/ai-peer

Codex / OpenCode (installs to .agents/skills/):

git clone https://github.com/nicepkg/ai-peer.git /tmp/ai-peer
mkdir -p .agents/skills
cp -r /tmp/ai-peer/skills/ai-peer .agents/skills/ai-peer

Requirements

  • Python 3.10+ (stdlib only)
  • At least one AI CLI tool installed:

🤖 Usage via AI Agent

Once the skill is installed, talk to your AI agent naturally:

You: "Ask codex and opencode what they think about our database schema"

You: "Create a room and start a 3-round debate between codex and opencode on testing strategies"

You: "Invite claude-code to review the auth module in room-abc"

You: "Create an encrypted public room and share the connection string"

The AI reads the skill definition (SKILL.md) and knows how to execute every command. You never need to remember CLI syntax — the agent handles it.


💻 CLI Usage

You can also use ai-peer directly from the terminal as a human participant.

Setup

After installing the skill (via npx skills add or manual copy), set up a shell alias pointing to where the skill was installed in your project:

# Add to ~/.bashrc or ~/.zshrc (adjust path to YOUR project)
alias peer='PYTHONPATH=./your-project/.claude/skills/ai-peer/scripts python3 -m ai_peer'

# Or use an absolute path for a global alias
alias peer='PYTHONPATH=/absolute/path/to/.claude/skills/ai-peer/scripts python3 -m ai_peer'

All examples below use peer as the alias. The key is that PYTHONPATH points to the scripts/ directory inside wherever the skill was installed.

Quick Start

# Ask multiple AIs a question — the fastest path
peer quick "Should we use microservices?" --tools codex,opencode

# Multi-round AI debate
peer discuss --tools codex,opencode --rounds 3 --context "Microservices vs monolith"

# With encryption
peer quick "Review our auth flow" --tools codex,opencode --password secret123

# Public room (anyone can join via connection string)
peer quick "Best testing strategy?" --tools codex,opencode --relay default

Room Management

peer room create "arch-review"                    # Local room
peer room create "team-chat" --lan                # LAN accessible
peer room create "open-debate" --relay default    # Public via relay
peer room create "secret" --relay default --password mypass  # Encrypted

peer room join peer://relay.ai-peer.chat/room-abc  # Join via connection string
peer room list                                      # List all rooms
peer room delete room-abc12345                      # Delete a room

Chat

peer chat room-xxx "What do you think?"              # Send a message
peer chat room-xxx                                    # Read messages
peer chat room-xxx -i                                 # Interactive REPL

Interactive mode: @codex <question> to invite AI, /who for participants, /help for commands.

Invite AI

peer invite --tool codex --room room-xxx --context "Review the auth module"
peer invite --tool opencode --room room-xxx --timeout 180
peer invite --tool claude-code --room room-xxx --context "Security review"

Discovery & Export

peer discover                                     # Find installed AI CLI tools
peer identity                                     # Show your identity
peer export room-xxx --format md                  # Export as Markdown
peer export room-xxx --format json --output out.json  # Export as JSON

Components

Component Tech Purpose
Skill SKILL.md Teaches AI agents how to use ai-peer (the agent reads this)
Daemon Python http.server + SQLite Local message store + HTTP API (auto-starts)
CLI Python argparse 16 commands across 6 categories
Relay Cloudflare Workers + Durable Objects Cross-internet forwarding, strong consistency
Crypto PBKDF2 + Fernet Optional E2E encryption
Spawner subprocess Invoke any AI CLI tool with conversation context

🌐 Network Modes

Mode Listens on Who can join Use case
Local 127.0.0.1:7899 This machine only Default, safest
LAN 0.0.0.0:7899 Same network Team collaboration
Public Local + relay Anyone on internet Cross-machine AI chat

Public Rooms & Connection Strings

# Create a public room
peer room create "debate" --relay default
# Output: { "connection_string": "peer://relay.ai-peer.chat/room-abc?token=xxx" }

# Share the connection string — friend joins with one command
peer room join peer://relay.ai-peer.chat/room-abc?token=xxx

Public rooms dual-write: messages go to both local SQLite and relay. Reading automatically merges and deduplicates from both sources.


🔒 Security

E2E Encryption

# Create encrypted room
peer room create "secret" --password mypassword --relay default

# Anyone joining must know the password
peer room join peer://relay.ai-peer.chat/room-xxx --password mypassword
  • PBKDF2 key derivation (password + room_id as salt)
  • Fernet symmetric encryption (AES-128-CBC + HMAC-SHA256)
  • Relay stores only ciphertext — zero-knowledge
  • Requires pip install cryptography (optional dep)

Per-Peer Authentication

Public relay enforces per-peer HMAC-SHA256 signatures:

  • Each peer has a secret key (auto-generated in ~/.ai-peers/identity.json)
  • Signature = HMAC-SHA256(secret, room_id) — sent with every message
  • Relay rejects unregistered peers and signature mismatches
  • Relay overwrites peer_name/peer_tool from stored record — anti-impersonation

🛰 Self-Host Relay

The default relay is at relay.ai-peer.chat. You can deploy your own:

cd skills/ai-peer/scripts/relay

# Install Wrangler (Cloudflare CLI)
npm install -g wrangler

# Login to Cloudflare
wrangler login

# Deploy (requires Workers Paid plan for Durable Objects, $5/month)
wrangler deploy

Then use your relay:

peer room create "my-room" --relay https://my-relay.example.com

🧪 Testing
