Every major cloud provider will let you use its infrastructure for free — at least, a little of it. AWS, Google Cloud, and Microsoft Azure each run generous free-tier programs designed to do one thing: get you through the door. If you are learning, prototyping, or running a small project, those free allowances can carry you a surprisingly long way. But free tiers are not all the same, and each comes with limits, expiry dates, and fine print that can turn a “free” experiment into a surprise bill.
This guide compares the major cloud free tiers side by side: what you actually get, how long it lasts, who each one suits best, and the traps that catch beginners. Terms change over time, so treat the specifics here as a starting point and always check current terms on each provider’s pricing page before you commit. For the broader picture of how cloud billing works once you outgrow the free tier, see our guide on how cloud hosting pricing actually works.
How Free Tiers Actually Work
Before the comparison, it helps to understand the three flavors of “free” that cloud providers offer, because they are often mixed together on marketing pages:
- Always-free allowances. A small monthly quota that never expires — a modest virtual machine, a chunk of storage, a slice of database capacity. As long as you stay under the cap, you pay nothing. Go over it, even by a little, and you are charged normal rates for the excess.
- Time-limited trials. A credit balance or full-access trial that lasts 90 days, 12 months, or similar. These usually unlock a much bigger slice of the platform, but they have a hard end date. When the trial ends, anything still running starts billing at standard rates.
- Credits and promos. Startup programs, student packs, and event coupons that add credit to your account. Useful, but temporary — treat them as a runway, not a foundation.
Most providers combine the first two: an always-free baseline plus a time-limited trial. The trick is knowing which resources fall into which bucket. A virtual machine might be always-free, while the same provider’s managed database is free only during the trial. Mix them up in one architecture and half your stack can start billing while the other half stays free.
Free Tier Comparison: AWS, Google Cloud, and Azure
Here is how the three big platforms stack up. Figures are the headline allowances as of 2026 — providers adjust these periodically, so verify before you build.
| Feature | AWS | Google Cloud | Microsoft Azure |
|---|---|---|---|
| Trial credit | 12-month free tier (no lump credit for most accounts) | Generous trial credit balance for new accounts | Trial credit balance for new accounts |
| Free virtual machine | Yes — a small instance type, capped monthly hours for 12 months | Yes — one small VM instance always free in select regions | Yes — small VM hours per month for 12 months |
| Object storage | Small always-free storage allowance (12 months) | Small always-free storage allowance | Storage allowance during trial period |
| Managed database | Small database instance free for 12 months | Small Cloud SQL allowance within trial limits | Database allowance during trial period |
| Always-free beyond trial | Limited — most quotas expire after 12 months | Strongest always-free program of the three | Limited — focused on the first year |
| Bandwidth included | Small outbound data allowance (12 months) | Outbound data allowance within free tier | Outbound data allowance during trial |
| Credit card required | Yes | Yes | Yes |
| Who it favors | Deep learners, certification students | Hobbyists and tiny always-on projects | Microsoft-ecosystem users, Windows workloads |
That table is the skeleton. The useful part is what each tier feels like in practice, which is where the verdicts come in.
AWS Free Tier: Best for Serious Learners
AWS structures its free offering around a 12-month free tier for new accounts. During that first year you get meaningful quotas across compute, storage, and databases — enough to run a small web application, follow certification coursework, and experiment with managed services like serverless functions and queues.
What makes the AWS free tier distinctive is breadth: dozens of services carry some free allowance. But breadth is also the risk. It is easy to spin up a service you have never heard of, forget about it, and discover it was only free during month one — or free only below a quota you sailed past. AWS’s billing alerts exist precisely because this happens constantly.
Best for: developers studying for AWS certifications, anyone who wants to learn the platform properly over a full year, and prototypes with a defined end date.
Watch out for: the 12-month cliff. Mark the expiry date in your calendar. Anything still running on day 366 bills at full price, and AWS will not remind you with enough urgency. Also note that the always-free tier after year one is thin compared with Google’s — plan your exit or your budget accordingly.
Google Cloud Free Tier: Best for Tiny Always-On Projects
Google Cloud runs two things in parallel: a trial credit for new accounts and an always-free program that is the strongest of the three providers. A small virtual machine in select regions, a chunk of storage, and slices of several managed services stay free indefinitely, with no 12-month guillotine hanging over them.
In practice, this means you can host a low-traffic website, a personal API, or a small database on Google Cloud and pay literally nothing, month after month, as long as you stay within the quotas. For hobbyists and side projects, it is the closest thing to a permanently free tier-one host.
Best for: personal projects, portfolio sites, learning experiments you want to leave running indefinitely, and anyone who values “set it and forget it” without a trial clock ticking.
Watch out for: region restrictions — the always-free VM only applies in certain regions, and deploying elsewhere opts you out of the free allowance silently. Also, the trial credit and always-free quotas are separate buckets; the console’s billing view blends them, so check which bucket each resource draws from.
Azure Free Tier: Best for the Microsoft Crowd
Azure’s free offering mirrors the industry pattern: a trial credit for new accounts plus 12 months of free quotas on popular services. Where it stands out is for anyone already in the Microsoft ecosystem — Windows Server workloads, .NET applications, SQL Server, and organizations that buy Microsoft 365 or hold enterprise agreements often find Azure’s trial dovetails with discounts and credits they already have.
The free allowances cover the usual suspects: small VMs, storage, and a slice of database and AI services. Azure also leans into free access for students through its education programs, which can extend well beyond the standard trial.
Best for: .NET developers, Windows-based workloads, students, and businesses already buying Microsoft products who can stack credits and enterprise discounts.
Watch out for: Azure’s service catalog is enormous, and free-tier eligibility varies by service in ways that are not always obvious from the portal. As with AWS, the 12-month boundary matters — audit everything before the trial ends.
Worth Knowing: Other Providers’ Free Offers
The big three are not the only game. A few others run notable free programs:
- Oracle Cloud offers an always-free tier that is unusually generous on paper — multiple small VMs and storage with no time limit. The catch is account verification friction and a history of aggressive fraud-prevention that occasionally locks out legitimate users.
- Cloudflare is not a general cloud provider, but its free plan (CDN, DNS, basic DDoS protection, Workers with a free quota) pairs beautifully with any of the above and costs nothing.
- Smaller VPS hosts rarely offer free tiers, but many offer a few dollars of trial credit or a money-back window — a different, simpler kind of “try before you buy.”
If your goal is learning one platform deeply rather than comparing several, pick based on where you want your skills or your business to live. Our AWS vs Google Cloud vs Azure comparison for small business walks through that decision in full.
Five Free-Tier Gotchas That Cause Surprise Bills
1. A credit card is required — and it can be charged
All three providers require a payment method to open an account. “Free” means “free within the allowances,” not “we cannot bill you.” Set up billing alerts on day one — every provider offers them — and set the threshold low.
2. Regions change the rules
Free quotas are often region-specific. The classic mistake: following a tutorial that deploys to a popular region while the free allowance only covers a quieter one. Always check the region column in the free-tier documentation, not just the service column.
3. Bandwidth is the silent killer
Compute and storage get the marketing attention, but outbound data transfer is the line item that surprises beginners. A small site that goes mildly viral can burn through a free bandwidth allowance in a day. Put a CDN in front of anything public-facing and monitor transfer from the start.
4. Forgotten resources bill forever
The number-one cause of surprise cloud bills is not a pricing trap — it is a forgotten load balancer, an unattached disk, or a database left running in a second region. Get in the habit of tagging everything you create and doing a weekly “what is running?” review during any trial.
5. Trial expiry is a cliff, not a slope
Trials end on a date, not gradually. Two weeks before expiry, decide: shut it down, migrate to always-free resources, or start paying deliberately. “I will deal with it later” is how a learning project becomes a monthly line item.
Free Tier FAQ
Are cloud free tiers truly free?
Within their stated allowances, yes — the providers honor them. The bills come from exceeding allowances, using services outside the free tier, or letting trials expire. Free tiers are honest; they are just narrow.
Can I open multiple accounts to stack free tiers?
Do not. Every provider prohibits gaming free tiers with multiple accounts, and they enforce it — usually by closing the accounts and billing the card on file. One account, used carefully, is the way.
Can I run a real business on a free tier?
A very small one, sometimes. A low-traffic brochure site or internal tool can live inside always-free quotas. But the moment you have customers depending on you, you need the monitoring, support, and headroom of a paid plan. Free tiers are for learning and prototyping; production deserves a budget.
How often do free-tier terms change?
More often than you would like. Providers adjust quotas, eligible services, and trial credits every year or two. Before making any decision based on a free tier, open the provider’s current free-tier page and read it fresh — never rely on a blog post’s numbers alone (including this one).
The Bottom Line
For learning over a full year with the widest service catalog, AWS is the natural pick. For a tiny project you want to leave running free indefinitely, Google Cloud’s always-free tier is unmatched. For Microsoft-ecosystem work, students, and .NET workloads, Azure fits best. None of them is a free lunch forever — but used deliberately, with billing alerts on and expiry dates in your calendar, each one is a genuinely useful on-ramp to the cloud. And when you are ready to spend real money with eyes open, our pricing explainer will make sure the first paid bill holds no surprises either.
