The ongoing monthly free quota applies only to R2 Standard storage, NOT Infrequent Access (which also has retrieval fees). Storage and request usage above the allowance are billed; track billable-unit rounding and avoid confusing free egress with free storage.

Storage/operations Free Tier applies only to us-east1, us-west1 and us-central1, aggregated across these regions. The 100 GB North America outbound allowance excludes destinations in China and Australia; not all egress routes are free. Billing account/payment method required; unsupported locations, storage classes and overages may be billed.

The 20 GB is shared across storage classes, not 20 GB per class. Accounts with paid/trial credits instead get 10 GB each in Standard, Infrequent Access and Archive plus 50.000 requests/month. Oracle warns objects exceeding the 20 GB Always Free-only limit may be deleted when the 30-day trial ends without upgrade. OCI account/payment verification and home-region restrictions apply.

Free quotas are hard caps: the bucket stops serving requests until the rolling 30-day window resets, with no Free-plan overage charge. Adding a credit card switches to pay-as-you-go billed from the first byte/operation, with NO continuing Free allowance. Reads/metadata lookups are simple operations; uploads, copies and listings are advanced; deletes are free.

Delivery stops at the monthly bandwidth cap; uploads stop at storage cap; no custom domain included; commercial-use terms and card requirement need confirmation.

1 credit equals 1.000 transformations OR 1 GB storage OR 1 GB delivery; combined usage counts toward 25-credit allowance. Exceeding limits may disable service after warnings.

Free storage covers Standard tier only. Usage beyond the allowance is billed; object notifications cost $0.01/1,000 events. Other storage tiers have separate retrieval fees or minimum retention periods.

2 GB storage is shared across all apps, not 2 GB per app. Private files, configurable regions and longer audit logs require paid tiers. Provider pricing does not clearly state signup card requirements or commercial-use permission; verify before use.

No free vendor-hosted object storage is included. Confirm the current community distribution, licensing, maintenance status, and support before production use.

Free software is not free managed capacity; supply disks, network, backups, and operations. Check replication configuration, current project support, and license conditions.

Requires your own storage nodes, networking, capacity planning, operations and often an authentication service; disk, bandwidth and infrastructure are not free. Not a hosted storage allowance.

Restic is backup software, not a hosted storage quota. You supply storage, compute and any cloud-provider fees; configure retention, credentials and restores yourself.

MIT-licensed software only; remote storage quotas, API calls, bandwidth, hosting and provider charges are separate.

BSD 3-Clause licensed backup software; requires your own backup storage and infrastructure; remote hosting or transfer may cost extra.

Backup destination storage, bandwidth and cloud API charges are separate; optional proprietary Duplicati features and paid services are not included. Test restore procedures.

Bring your own filesystem, TLS, identity configuration and backup; the v2 line is described as beta by maintainers, so evaluate release stability and security before internet exposure. Distinct maintained fork of archived original File Browser.

Requires dedicated self-managed Debian host and physical/virtual disks; project expects exclusive control of OS configuration and cannot run in a container. Storage, backup hardware, electricity and maintenance are not included.

Free plan is positioned for side projects/experimentation; AI processing and larger limits require Pro. Media library is hosted by Stow; commercial-use terms are not explicit.

Nubbo manages third-party storage and does NOT include storage capacity or bandwidth; your S3 provider may charge separately. Public API and advanced features are planned for paid plans; card and commercial terms unconfirmed.

This is software, not a free hosted S3 bucket. You provide disks, compute, backups and security; external cloud storage backends can incur charges. The upstream README documents example default access keys that must be replaced for real deployments.

Free Home tier is marketed for home use and evaluation; suitability for production business use should be confirmed. Paid Connect/Enterprise add SSO, LDAP, compliance and support. Hosting, storage and backups are user-funded; AGPLv3 source-sharing obligations may apply.

Free 10 GB is a one-time eligibility-checked signup grant: VPN/proxy or anonymization-network signups may receive no free storage, with no later manual grant. Business use and card requirements need confirmation.

Requires a Kubernetes cluster and sufficient node disks, CPU, networking and backup targets; cloud disks and object-storage backup traffic may incur charges. Replica count increases physical storage consumption.

You must supply storage, Docker/server capacity, backups and network security; no hosted storage allowance is included. The app can modify files on mounted volumes, so restrict mounts and sharing permissions. Provider branding and external infrastructure costs are separate.

Requires separate Kubo/IPFS peers, disk, compute, networking and ongoing pin availability. This is pin orchestration rather than a managed free pinning service; third-party pinning/gateway services may charge. Verify upstream maintenance and security before production use.

Runs on user-provided hardware, disks and bandwidth; remote pinning, public gateways and hosting may cost money. IPFS content is not automatically durable unless pinned and reachable. Official upstream README states there is no dedicated maintainer after Shipyard maintenance ended 2026-09-30; assess security and operational risks before production use.

Self-host the management server and agents, configure storage/retention and verify restorations; backup destinations, storage capacity and compute are not supplied free. Some database engines and operations have different restore capabilities; review official compatibility docs.
