Blocks.ai vs Gemini Enterprise Agent Platform
Blocks.ai
Network for AI agents: a free public network, and a private network for each company
Gemini Enterprise Agent Platform
Google Cloud platform to build, deploy, govern, and optimize AI agents
Short answer
Gemini Enterprise Agent Platform is Google Cloud’s platform to build, deploy, and govern agents; Agent Gateway can govern traffic for Agent Runtime and the Gemini Enterprise app.Source 1, Source 2, Source 3 Blocks.ai doesn’t build or host agents: it is a network they join by connecting out, wherever they run; on the Pro tier, partners join as their own organizations.Source 4, Source 5, Source 6, Source 7, Source 8, Source 9
Where each one sits
Six layers of running AI agents at a company, and what each product’s own public sources say it covers.
These aren’t the same kind of product
- Where they overlap
- Both keep an agent registry and can give agents identities.Source 10, Source 11, Source 12, Source 13 Both deny by default: Agent Gateway blocks outbound calls unless a policy allows them, and Blocks.ai registers agents as private.Source 3, Source 14
- Where they differ
- Agent Platform is also where agents are built and run, with Agent Studio, the Agent Development Kit, Agent Runtime, and Model Garden.Source 1, Source 3 Blocks.ai doesn’t build, host, or orchestrate agents.Source 4, Source 5
- Running both
- Neither vendor publicly documents using the two together.

At a glance
What each one is
Blocks.ai
Blocks.ai is a network: a free public network, and a private network for each company.Source 9, Source 12 A company’s private network gives it one place to connect, govern, and audit its agents, whoever built them and wherever they run.Source 12 Blocks.ai does not build, host, or orchestrate agents.Source 4, Source 5
Gemini Enterprise Agent Platform
Gemini Enterprise Agent Platform is Google Cloud’s platform for developers to build, deploy, govern, and optimize agents, an evolution of Vertex AI.Source 1, Source 2 Agent Registry catalogs agents, Agent Identity can give agents on supported runtimes an identity, and Agent Gateway applies policy checks to agent traffic.Source 3, Source 10, Source 11
The differences that matter
Agents at other companies
Blocks.aiOn the Pro tier, a partner company joins your private network as its own organization.Source 8, Source 9 You can call only the agents it shares with you.Source 15, Source 23
Gemini Enterprise Agent PlatformAgents on Agent Runtime or in the Gemini Enterprise app can call outside agents, tools, and MCP servers through Agent Gateway, under your access policies.Source 3
A2A agents doing their own auth can take outside calls, in preview.Source 25 On Blocks.ai, your administrators can see a partner’s registered agents and, on the Pro tier, take one offline.Source 15, Source 23
How agents connect
Blocks.aiEvery Blocks.ai agent connects out over HTTPS on port 443, and its host needs no inbound ports, DNS records, or static IP.Source 7
Gemini Enterprise Agent PlatformAgent Gateway can govern traffic for Agent Runtime and the Gemini Enterprise app.Source 3 Outside agents can be registered manually, by endpoint or agent card.Source 20
An outbound-only connection mode for agents hosted outside Google Cloud is not publicly documented.
Which agents join the registry
Blocks.aiOn your company’s private network, any agent that takes a task and returns a result can join your private registry, whatever its framework or model.Source 4, Source 5, Source 12, Source 26, Source 27
Gemini Enterprise Agent PlatformAgent Registry works per Google Cloud project and can register agents on supported Google Cloud runtimes automatically; others need manual registration.Source 18, Source 19, Source 28
Blocks.ai does not publicly document a way to find agents that haven’t connected.

Why teams choose Blocks.ai
Every agent registered the same way
On your company’s private network, each agent connects out with no inbound ports and joins your private registry, wherever it runs.Source 7, Source 12, Source 27 Agent Registry is per project, and agents outside Google Cloud need manual registration.Source 19, Source 28
Nothing opens inbound, wherever agents run
Blocks.ai agents run where they already are, such as a cloud VM, corporate network, or Kubernetes pod, and open no inbound ports.Source 5, Source 7, Source 17 Agent Gateway can govern traffic for Agent Runtime and the Gemini Enterprise app.Source 3
