THE GOOGLE CLOUD FREE TIER: 20+ PRODUCTS YOU CAN USE FOR $0

Yes, Google Cloud is free to start — in two ways that stack. New accounts get $300 in credits to spend over 90 days, and on top of that, 20+ products stay free every month within set limits that never expire. The first is a trial; the second is permanent. Confusing the two is the most common beginner mistake, so we'll separate them cleanly, give you the real numbers, and show you how to stay at $0.

The two free things (don't confuse them)

The $300 free trial credit. Every new account gets it, valid for 90 days. You can spend it on almost anything — bigger VMs, Cloud SQL, Vertex AI, GKE clusters. When the 90 days end or the $300 runs out (whichever comes first), paid resources stop. You enter billing details to sign up, but you're not charged until you actively upgrade.

The Always Free tier. A separate, permanent allowance on 20+ products. As Google puts it on the free program page, usage up to these limits isn't charged against your $300 credit and the limit doesn't expire (though it's subject to change). This is the part that lets you run a small project indefinitely.

The Always-Free products worth knowing

You don't need all 20+. These are the ones that carry real projects:

Limits are accurate as of June 2026 and change periodically — confirm current values on cloud.google.com/free.

Two are quietly excellent for beginners: Cloud Run (charges only while handling a request, and 2M/month covers most small apps) and BigQuery (1 TB of queries is a lot of learning). Both avoid the classic trap of an always-on resource billing you around the clock.

What is NOT free (the surprise-charge culprits)

The danger isn't the free products — it's stepping outside them without noticing.

• Egress. Putting data into Google Cloud is free; serving it out to the internet costs money. Stream large media straight from a Storage bucket and the egress bill bites. Front it with a CDN.
• Wrong region. The free e2-micro only applies in three US regions. Spin one up in Europe or Asia and it's billable from minute one.
• Trial-only services. Cloud SQL, Dataflow, Pub/Sub beyond its allowance, and larger VMs are free during the $300 trial, then they charge. Don't mistake "free on trial" for "Always Free."
• Quotas are per billing account, not per project. Three projects under one account share one e2-micro and one 5 GB Storage quota — not one each.

How to stay at $0

Two guardrails handle nearly all of it:

1. Set a budget alert on day one. In Billing → Budgets & alerts, set a budget (even $1) with email alerts. It won't auto-stop spend, but you'll know the instant anything leaves the free tier.
2. Prefer scale-to-zero products. Cloud Run and Cloud Functions cost nothing when idle. Always-on VMs and managed databases keep billing whether you use them or not — reserve those for when you genuinely need them.

What to build first on free

Skip the reading and deploy something. Open a free account, then launch one Application Design Template from the console — a three-tier web app or a BigQuery data warehouse. You'll learn the platform's shape in an hour, entirely within the free allowance, and you'll have a running thing to point an AI agent at next.
