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 connects them where they already run and lets you decide who can reach each one, including other companies.⁠Source 4, Source 5, Source 6

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 7, Source 8, Source 9, Source 10 Both deny by default: Agent Gateway blocks outbound calls unless a policy allows them, and Blocks.ai registers agents as private.⁠Source 3, Source 11
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.

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 22 A company’s private network gives it one place to connect, govern, and audit its agents, whoever built them and wherever they run.⁠Source 9 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 7, Source 8

The differences that matter

  1. Agents at other companies

    Blocks.ai

    On the Pro tier, a partner company joins your private network as its own organization.⁠Source 21, Source 22 You can call only the agents it shares with you.⁠Source 12, Source 23

    Gemini Enterprise Agent Platform

    Agents 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 12, Source 23

  2. How agents connect

    Blocks.ai

    Every Blocks.ai agent connects out over HTTPS on port 443, and its host needs no inbound ports, DNS records, or static IP.⁠Source 15

    Gemini Enterprise Agent Platform

    Agent 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 18

    An outbound-only connection mode for agents hosted outside Google Cloud is not publicly documented.

  3. Which agents join the registry

    Blocks.ai

    On 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 6, Source 9, Source 26

    Gemini Enterprise Agent Platform

    Agent Registry works per Google Cloud project and can register agents on supported Google Cloud runtimes automatically; others need manual registration.⁠Source 16, Source 17, Source 27

    Blocks.ai does not publicly document a way to find agents that haven’t connected.

Which to choose

Choose Blocks.ai if

  • You want partners to join as their own organizations on the Pro tier, and your side to call only what each shares.⁠Source 12, Source 21, Source 22, Source 23
  • Your agents run across clouds and corporate networks, including behind proxies, where opening inbound ports is hard or not allowed.⁠Source 5, Source 14, Source 15
  • Your teams use many frameworks and models, and you want every agent in your company’s private registry, deciding who can call each.⁠Source 4, Source 6, Source 9, Source 23, Source 26
  • Your agents run outside Agent Runtime and the Gemini Enterprise app, and you want to connect, govern, and audit them in place.⁠Source 3, Source 5, Source 9

Choose Gemini Enterprise Agent Platform if

  • You want one Google Cloud platform to build, host, and govern agents, from Agent Studio to Agent Runtime, with over 200 models.⁠Source 1, Source 3, Source 13
  • You want policy enforced at a gateway, with outbound calls blocked by default and Model Armor scanning prompts and tool responses.⁠Source 3
  • You need agent data at rest kept in a location you select, and ISO, SOC, PCI DSS, and HIPAA BAA coverage.⁠Source 36, Source 37, Source 51
  • Your agents already run on Google Cloud, where agents on supported runtimes, such as Google Kubernetes Engine, can be registered automatically.⁠Source 16, Source 17

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 9, Source 15, Source 26 Agent Registry is per project, and agents outside Google Cloud need manual registration.⁠Source 17, Source 27

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 14, Source 15 Agent Gateway can govern traffic for Agent Runtime and the Gemini Enterprise app.⁠Source 3

Agents at other companies, today

On the Pro tier, partners join as their own organizations.⁠Source 21, Source 22 You can call only the agents they share with you.⁠Source 12, Source 23 Granting another organization IAM access to your Agent Runtime agents is not publicly documented.
