PubNub launches network for reachable AI agents

PubNub launched Blocks.ai on 8 July 2026 as a global network to connect and control AI agents across frameworks, providers and APIs.

From San Francisco, the company introduced Blocks Network for developers who need to reach existing agents wherever they are hosted. The setup does not require inbound ports, tunnels, DNS changes or firewall rule changes.

Many businesses run agents locally or behind a firewall. In those cases, custom frontends often need extra infrastructure work before they can reach the agents.

McKinsey estimates that fewer than 10% of enterprise agents have ever reached production. PubNub argues that brittle infrastructure is a key reason for that gap.

Blocks Network aims to remove that barrier while keeping the agent private and under the builder’s control. It supports AI agent use cases across any network and device.

Open-source SDKs and agent discovery

Developers who do not run an agent can still use the network. Any application, web app, backend service or mobile app can discover capability-specific agents and call them with a few lines of code through open-source SDKs.

Instead of managing a separate API key for every provider, developers can add AI functions in the same way they would call a function. Meanwhile, the agents behind those capabilities keep running wherever their builders host them.

Todd Greene, PubNub’s chief executive, said: “You can build a great agent in an afternoon, but it often just sits there, isolated on your machine.”

Greene called Blocks a global agent control plane that lets builders connect an agent once and then make it available to frontends, applications and users. He said the goal is to share efficiencies without rebuilding anything.

Code review, transcription and data extraction

Blocks.ai also lets agents call other agents on the same network, regardless of framework. The same connection that makes an agent reachable also gives it access to other agents’ capabilities.

Discoverable services on the network include code review, transcription, PDF generation, QR generation, data extraction and streaming compute. Builders can use those functions without maintaining separate integrations for each one.

For more than a decade, PubNub has provided real-time connectivity infrastructure that supports billions of devices. The company now presents Blocks Network as part of its push to connect the Internet of Agents.

Zero-trust security and 99.999% SLA

Blocks.ai runs on PubNub’s real-time backbone. Platform features include zero-trust security, a 99.999% SLA, SOC 2 compliance and GDPR compliance.

Blocks.ai supports agent frameworks, providers and APIs without lock-in. As a result, developers can connect and control agents across different systems without moving where those agents are hosted.
