Google Cloud Next 2026 is weeks away, and “Agentic AI” is the confirmed star of the show. The more practical story is what Google has already made available for developers who want to start building before the conference.
Google has publicly available credit programs and developer access paths for builders working with the Agent Development Kit (ADK) and Vertex AI Agent Engine. In this guide, I will walk you through the legitimate, publicly available Google Cloud credit programs and developer access paths for building with Agentic AI tools in 2026.
What this guide covers:
- What Agentic AI means on Google Cloud in 2026 (ADK, Agent Engine, A2A Protocol)
- Verified Google Cloud credit programs and who qualifies
- How to apply for ADK and Agent Engine early access
- Step-by-step setup resources to start building today
What Exactly is Google’s “Agentic AI”?
Google defines Agentic AI on its platform this way. In 2026, “AI” is a broad term, but “Agentic AI” is a specific technical architecture. Unlike standard chatbots that wait for a prompt to generate text, Agentic AI uses the A2A (Agent-to-Agent) protocol. This allows AI systems to talk to each other, negotiate budgets, and execute multi-step workflows without a single human click.
Key Tools You Need to Know:
- Vertex AI Agent Builder: Consider this your “no-code” entry point. It’s designed for rapid prototyping of agents that can access your internal data securely.
- Agent Development Kit (ADK): This is the code-first framework for developers. It allows for complex logic, state management, and custom integration with the A2A protocol.
- Agent Engine: The managed infrastructure where these agents “live.” It handles the low-latency scaling required for agents to operate autonomously 24/7.
ADK vs. Vertex AI Agent Builder: Which One Do You Need?
| Tool | Best For | Skill Level | A2A Support |
|---|---|---|---|
| Vertex AI Agent Builder | Rapid prototyping, no-code/low-code agents | Beginner–Intermediate | Limited (via Dialogflow CX integration) |
| Agent Development Kit (ADK) | Custom logic, stateful workflows, multi-agent systems | Intermediate–Advanced | Full native support |
| Agent Engine | Production deployment and scaling of built agents | Intermediate–Advanced | Runtime infrastructure for A2A |
Note: Agent Engine is currently in GA with some features still in Preview. Check regional availability before starting production builds.
Three Verified Ways to Access Google Cloud Credits for Agentic AI
Option 1: Google for Startups Cloud Program (Verified Tiers)
The Google for Startups Cloud Program offers tiered credits based on your startup’s funding stage:
- Start Tier: Up to $2,000 USD in credits (valid 1 year) — for pre-funding, early-stage tech startups founded within the last 5 years [1]
- Scale Tier: Higher credit amounts for funded startups from pre-seed to Series A (raised within last 12 months) — exact amounts vary and are confirmed during application review [1]
Eligibility requirements (both tiers):
- Must be a technology startup (not an agency or consulting firm)
- Must not have previously received more than $5,000 in Google Cloud credits
- Company domain must not have an active paid Google Cloud subscription
Apply directly at cloud.google.com/startup. Applications are reviewed on a rolling basis.

Option 2: Google Cloud Innovators Program
The second way to get Google Cloud credits for Agentic AI is to look for Google-led learning programs that include hands-on labs and occasional credits. For example, Google for Startups Accelerator, skills challenges, or certification campaigns.
Google sometimes runs limited‑time programs for active developers (for example, skills challenges, Innovators Plus, and regional certification campaigns). These usually combine structured learning paths, hands‑on labs, and occasional credits or vouchers for eligible participants.
Because these programs change frequently and some legacy offerings, such as Google Cloud Innovators, have closed to new registrations, always read the current eligibility notes on the official program page before you sign up.
Option 3: Google Cloud Skills Boost and Free Tier Credits
Google offers a $300 free trial credit valid for 90 days, available to any new Google Cloud account. This is the fastest way to start experimenting with ADK and Agent Engine at no cost.
Google Cloud Skills Boost occasionally offers lab credits during specific learning events. The Cloud OnAir webinar series — including the 2026 AI in Action sessions — provides free hands-on labs during registration windows. Credits available through these events are tied to specific lab environments, not general-purpose compute credits.
- Free Trial: $300 credit, 90 days, all Google Cloud services, including Vertex AI
- Skills Boost Labs: Free individual labs available at cloudskillsboost.google
- Cloud OnAir Events: Register at cloudonair.withgoogle.com for upcoming Agentic AI developer sessions with free lab access
How to Apply: Writing a Strong Use Case Description
When applying for any Google Cloud credit program, the “use case” field is your most important input. Google’s review teams assess whether your project is a real technical build, not a vague experiment. Here is what to focus on:
- Be specific about what you are building: Describe the agent’s function, the data sources it will access, and the workflow it automates.
- State the technical stack: Mention the specific Google Cloud tools you plan to use (e.g., ADK, Agent Engine, Vertex AI, BigQuery).
- Describe the scale you need: Estimate your expected API calls, storage needs, or number of concurrent agents. This shows genuine technical planning.
- Explain the user or business problem being solved: Applications that describe a real problem and a measurable outcome are stronger than generic AI experiment descriptions.
There is no secret formula. Google’s programs are designed to support builders doing real work. A straightforward, technically honest description of your project is the most effective application.
Getting Started With ADK Before Google Cloud Next 2026
If you want to arrive at Google Cloud Next 2026 with a working agent prototype, the official ADK quickstart is the fastest path. Google’s documentation covers environment setup, agent deployment, and connecting to Agent Engine in a structured five-step flow:
- Set up your Google Cloud project and install the Vertex AI SDK for Python
- Develop your first agent using the ADK framework
- Deploy the agent to Vertex AI Agent Engine
- Query the agent via API request
- Manage and iterate on your deployed agent

Last Say!
The credits are available, but they are tucked away in the corners of the Google Cloud ecosystem.
Whether you are a developer testing ideas with the $300 free trial or a funded startup applying for the Scale Tier program, the path forward is the same: start with a clearly defined agent use case, use the right tool for your skill level (Agent Builder for speed, ADK for control), and deploy via Agent Engine when you are ready to scale.
The transition from generative chat to autonomous agency is the biggest shift in computing since the cloud itself. We’ve seen the power of these tools firsthand, and the edge goes to those who start today.

Frequently Asked Questions
Is Google Cloud ADK free to use?
ADK itself is an open-source framework and is free to download and develop with locally. Costs are incurred when you deploy to Vertex AI Agent Engine or use Gemini API calls in production. New Google Cloud accounts receive a $300 free trial credit to cover initial experimentation.
What is the difference between ADK and Vertex AI Agent Builder?
Vertex AI Agent Builder is a no-code/low-code interface for building agents quickly, designed for teams that want fast prototyping without deep coding. On the other hand, ADK (Agent Development Kit) is a code-first Python framework for developers who need custom logic, complex state management, and full control over multi-agent workflows. Both deploy to Agent Engine in production.
How do I qualify for the Google for Startups Cloud Program?
You need to be a technology startup having spent around 5–10 years (depending on tier), not have received more than $5,000 in prior Google Cloud credits, and your company domain must not have an active paid Google Cloud billing account.
What is the A2A (Agent-to-Agent) protocol?
A2A is an open protocol developed by Google that allows AI agents to communicate with each other, delegate sub-tasks, and coordinate multi-step workflows without direct human intervention. It enables building systems where specialized agents (e.g., a data-fetching agent, a decision agent, a notification agent) work together autonomously. ADK has native A2A support for building these multi-agent architectures.
