6 free alternatives to Backblaze B2 Cloud Storage

Amazon S3's free offer is not a standing storage allowance. It gives eligible accounts up to $200 in AWS Free Tier credits, usable across AWS services including S3, for 6 months after account creation, with credits expiring within 12 months. That makes it useful for short evaluation windows or for teams already planning an AWS setup. The main advantage over Backblaze B2 is the larger introductory value, especially if you need to test adjacent AWS services too. It falls short on ongoing free storage because the benefit is time-limited, not perpetual. Switch here if you want a broad AWS trial rather than a long-lived free bucket.

• Beats Backblaze B2 Cloud Storage: More introductory value through $200 in AWS Free Tier credits across AWS services.
• Falls short: No perpetual free storage allowance; the offer expires after the credit window.
• Who should switch: Switch to this if you need a short AWS trial and may also use other AWS services.

Cloudflare R2 gives a monthly free allowance of 10 GB-month of Standard storage, 1 million Class A operations, 10 million Class B operations, and free egress to the Internet. That is a cleaner fit if your concern is request volume as much as storage, because the operations quotas are explicit and egress stays free. Compared with Backblaze B2, it beats on monthly request headroom and has no egress charges on the free tier. It falls short on raw storage cap, since B2's 10GB free storage is larger in simple storage terms and B2 also allows free Class A, B, and C calls with no daily limit. Switch if your workload is small but request-heavy.

• Beats Backblaze B2 Cloud Storage: More request headroom with 1 million Class A and 10 million Class B operations per month.
• Falls short: Less straight storage headroom than Backblaze B2's 10GB free storage.
• Who should switch: Switch to this if you need free egress and your app is request-heavy rather than storage-heavy.

Tigris offers 5 GB of standard storage per month, 10,000 PUT, COPY, POST, and LIST requests, 100,000 GET, SELECT, and other requests, plus zero egress fees for data transfer out and region-to-region transfer. The free tier is smaller on storage than Backblaze B2, but it is broader on traffic because transfer out stays free and the request mix is spelled out. It is a good fit for developers who want S3-compatible storage with a tight but predictable monthly envelope. It falls short on storage capacity and on the total general-purpose ceiling that B2's 10GB free storage provides. Switch if your application is light on storage and you care most about avoiding egress fees.

• Beats Backblaze B2 Cloud Storage: Zero egress fees across data transfer out and regional transfers.
• Falls short: Only 5 GB of free standard storage, less than Backblaze B2's 10GB.
• Who should switch: Switch to this if your main pain point is outbound transfer charges rather than storage size.

SimpleBackups includes 1 backup job, 1 GB of SimpleStorage, daily backup frequency, email notifications, and backup encryption at $0 per month. This is not object storage in the same sense as Backblaze B2, but it is a practical free option if your real need is automated backups rather than a raw bucket. Its strongest advantage over B2 is the built-in backup workflow, with scheduling and notifications included from the start. It falls short badly on storage capacity and storage-style flexibility, since the included 1 GB is far smaller than B2's 10GB free storage and it is job-based. Switch if you want backup automation more than storage primitives.

• Beats Backblaze B2 Cloud Storage: Built-in backup job scheduling and notifications, not just storage.
• Falls short: Far less free storage, with only 1 GB included.
• Who should switch: Switch to this if your use case is a scheduled backup workflow instead of object storage.

Storj's free tier is a 30-day trial for Distributed Storage, Object Mount, and Cloud Compute, with no credit card required. That makes it the easiest option to test if you want to see whether a distributed storage and compute stack fits your workflow before committing. The main advantage over Backblaze B2 is the no-card trial access across multiple products, which can be helpful for evaluation. It falls short because it is only a trial, not a perpetual free tier, so it does not solve long-term zero-cost storage. Switch if you want a hands-on test drive with storage and compute together.

• Beats Backblaze B2 Cloud Storage: No credit card required for trial access to storage, Object Mount, and compute.
• Falls short: Only a free trial, not an ongoing free storage allowance.
• Who should switch: Switch to this if you want to evaluate a distributed storage platform before paying.

BorgBase gives 10 GB free backup hosting forever, with free backup storage for BorgBase accounts. That makes it the strongest perpetual no-cost choice in this set for encrypted offsite backups, especially if you use Borg or Restic. The biggest advantage over Backblaze B2 is that the 10GB free tier is ongoing and does not require a card, so it is a true long-term backup landing spot. It falls short if you need generic object storage or broader S3-compatible workflows, because it is purpose-built for backup repositories rather than general bucket use. Switch if your goal is simply to keep a small backup set online for free.

• Beats Backblaze B2 Cloud Storage: Perpetual 10 GB free backup hosting with no-card signup.
• Falls short: Backup-focused, not general-purpose object storage.
• Who should switch: Switch to this if you want a small, always-free offsite backup repository.
