Not a platform.
The network.
Blocks.ai is what happens after you build an agent. Connect it to Blocks Network wherever it sits, and the people and agents who need it call it from anywhere.
Building agents is solved. Reaching the world isn't.
The frameworks won — building an agent is a solved problem. OpenClaw, LangChain, CrewAI, and dozens of others make it straightforward to create an agent that works. The missing chapter is what happens after it works on your machine.
Making an agent reachable means dealing with servers, DNS, SSL, firewalls, authentication, rate limiting — spending more time on infrastructure than on the agent itself. Or maybe you have not tried, because there is no obvious product for this. No category. Nothing to search for. Supabase exists for databases. Vercel exists for deployment. For agent communication? Nothing.
Blocks fills that void. Your agent stays where it is. It connects outward to Blocks Network. Anyone, anywhere, can call it. That is the entire idea.
"The world does not need another agent platform. It needs a way to connect all the agents, everywhere."
The Blocks philosophy.
Infrastructure should disappear.
The best infrastructure is the kind you don't have to think about. Blocks makes agent connectivity invisible: you write the agent logic, we handle the rest.
Always open.
The SDK is Apache 2.0. We follow the A2A shape so agents you build on Blocks port cleanly when full A2A compliance lands.
Developer-first by design.
Our five-minute quickstart, config dashboard, and dev mode with no auth were designed with developers in mind.
Real-time is the default.
Blocks is built on real-time foundations with 15+ years of production use. Progress, artifacts, and observability stream live.

Background in real-time infrastructure and developer tools.
Previously built distributed systems at scale.
Focused on developer experience and agent workflows.

About the building (of) Blocks.
Built on PubNub.
Blocks is built on PubNub's real-time infrastructure — 15+ years in production, 99.999% SLA, powering billions of messages for enterprises worldwide. PubNub handles the communication layer: message delivery, presence, global routing, and security.
PubNub's outbound-only connection model is the structural property that makes Blocks possible. It is the same technology powering real-time chat, IoT device communication, and live gaming — environments where devices cannot expose server ports.
Build from anywhere.
The SDK is open.
The Blocks SDK — the code that runs on your machine — is open source under the Apache 2.0 license. You can read the source, audit the behavior, and trust the security model. Example agents are MIT-licensed.
We believe you should be able to inspect every line of code that runs on your machine. That is why the SDK is open.
