The AI-Native pub/sub platform built for agent communication
Currently in open beta—join early and help shape the platform.
Production-ready in minutes, not months. Connect, scale, and orchestrate AI agents without the complexity of enterprise platforms or DIY infrastructure.
AI-Native Architecture
Purpose-built for AI agents, not retrofitted. Scale from 10 to 10,000 agents with O(n) complexity instead of O(n²).
Production-Ready Security
NATS-native NKey authentication with optional TLS/SSL. Deploy with confidence using battle-tested security.
Minutes to Production
No complex setup or enterprise contracts. Start free, scale predictably, with transparent pricing that won't surprise you.
From chaos to clarity
Traditional agent architectures create exponential complexity. Our message bus approach scales linearly.
Direct connections
Exponential complexity
Tight coupling creates cascading failures
Configuration grows exponentially
Security becomes unmanageable
Message bus
Linear scaling
Loose coupling prevents cascading failures
Zero-config agent addition
Unified authentication and permissions
More than messaging. Built for AI agents.
Not another generic pub/sub service. Every feature designed specifically for AI agent communication, coordination, and scale.
AI-Native Message Bus
Purpose-built for AI agents, not retrofitted. O(n) scaling that actually works in production.
- Built for AI, not adapted
- O(n) vs O(n²) scaling
- Production-tested patterns
Production-Ready Security
NKey authentication built for AI agents. Deploy with confidence—TLS/SSL coming soon.
- Agent-specific NKeys
- No token sprawl
- Zero-trust ready
Multi-Agent Coordination
Enable agents to work together through topic-based messaging and event-driven workflows.
- Event-driven workflows
- Topic-based routing
- Async coordination
Flexible Architecture
Build any agent topology with pub/sub patterns. From simple pipelines to complex networks.
- Custom topologies
- Pipeline patterns
- Fan-out/fan-in
Tool Integration
Equip agents with tools and integrate with external services through our extensible framework.
- Tool decorators
- Service integration
- Custom handlers
Minutes to Production
Skip months of infrastructure setup. Start free, scale predictably, no surprises.
- 5-minute setup
- Transparent pricing
- No "contact sales"
Production-ready in 5 minutes
No complex setup. No enterprise contracts. Just AI-native pub/sub that works.
from artcafe_agent import ArtCafeAgent
# Create agent with credentials
agent = ArtCafeAgent(
agent_id="your-agent-id",
tenant_id="your-tenant-id",
private_key_path="agent_key.pem"
)
# Connect and subscribe
await agent.connect()
await agent.subscribe("tasks/new")
# Handle messages
@agent.on_message
async def handle_message(topic, data):
if topic == "tasks/new":
result = await process_task(data)
await agent.publish("tasks/complete", result)
# Keep running
await agent.run_forever()How it works
From agent chaos to orchestrated intelligence
See how ArtCafe.ai transforms complex agent communication into simple, scalable workflows with specialized agents as tools, swarm intelligence, and agent graphs.
Create your agent
The Problem
Traditional systems require complex setup and configuration
Our Solution
Simply define your agent and its capabilities. ArtCafe handles the infrastructure.
from artcafe import Agent
agent = Agent(
name="data-processor",
ssh_key_path="~/.ssh/agent_key"
)Connect to the network
The Problem
Point-to-point connections become unmanageable as you scale
Our Solution
Agents connect to our pub/sub network once. No need to manage individual connections.
pubsub = PubSub()
await pubsub.connect()
# Subscribe to relevant topics
await pubsub.subscribe("tasks/process")Start communicating
The Problem
Direct messaging creates tight coupling between agents
Our Solution
Use topic-based messaging for flexible, scalable communication.
@agent.on_message
async def handle_task(message):
result = await process_data(message)
# Publish results to interested agents
await pubsub.publish("results/processed", result)Scale effortlessly
The Problem
Adding new agents requires reconfiguring the entire system
Our Solution
New agents simply subscribe to relevant topics. Zero reconfiguration needed.
# Add a new agent anytime
new_agent = Agent(name="analyzer")
await new_agent.subscribe("results/processed")
# It automatically receives relevant messagesThe Power of Publish-Subscribe Architecture
Messages per second
Average latency
Agent scalability
AI-Native pricing that makes sense
Production-ready pricing, not enterprise games
No “contact sales” mysteries. Start free, scale predictably. Built for developers who need more than DIY NATS but can't afford enterprise AI platforms.
40% less than cloud providers. 80% less than enterprise platforms. 100% transparent.USD pricing. Production-ready from day one.
