S3 object storage that lives where your data works.
Fast reads, predictable pricing and the freedom to move your data without lock-in or egress penalties.
1 TB free for 30 days · No credit card required
Sovereign by design.
Optimized for AI.
Your data stays in your jurisdiction and under your control, next to the compute that uses it.
Close to your compute
Zones run in the EU and US today. New zones go where your GPUs already run.
Access you control
Give people, pipelines and AI agents keys scoped to one bucket, with role-based access and bucket policies.
Certified data centers
Facilities certified to ISO 27001 and SOC 2, with reports on request.
Proof, not promises
Verify your data with cryptographic proof, without downloading.
Built for data that stays in play.
Move finished checkpoints, backups, footage and logs to lower-cost storage, and pull them back at full speed when you need them.
Storage your team can rely on
- Reserved capacity for 1, 3 or 5 years with SLAs
- Role-based access, IAM and bucket policies, scoped keys
- Audit reports on request, migration guided by our team

Fil One speaks the S3 API. Your SDKs, CLIs and backup tools work as they are.

What builders are saying.
Robotics is in the early innings of data collection, and the datasets are already running into the petabytes, with demand climbing fast. The tech behind Fil One gives us scaled, genuinely cheap storage without egress penalties, which is exactly what an emerging sector like robotics data collection needs to move quickly. It's the storage layer we can grow into.
Fil One is one of the most ambitious efforts in all of web3, and integrating it lets our customers tap verifiable, content-addressed storage at planetary scale as a native part of how they build.

Frequently asked questions
Fil One speaks the S3 API, so you keep the SDK and CLI you already use. Point it at your region's endpoint, switch on path-style addressing, and authenticate with a Fil One access key. Everyday object work behaves the way your code expects: put, get, head, list, delete, presigned URLs, and multipart upload from your own SDK.
Buckets are private by default. For the operation-by-operation detail, including the calls that differ between regions, see the S3 compatibility reference in the docs.
Read Fil One docs, access the app to get started with no code required, or talk to someone on our team to get started.
Objects are encrypted at rest by the storage gateway using AES256 (SSE-S3), and every request runs over TLS. It is on by default with nothing to configure. Keys are held by the regional storage operator that fulfills your bucket's region, so if your policy requires you to hold the keys yourself, encrypt client-side before upload with the standard S3 tooling and Fil One stores the ciphertext. Our services are delivered through top-tier data centers that are certified to ISO 27001, SOC 2, and PCI DSS standards. Reach out to security@fil.one for compliance documentation or any other security questions.
After you create an account and provision your first bucket, migrating to Fil One is straightforward with our S3-compatible interface. Integrate directly into your codebase with any S3-compatible SDK, or migrate your data with a single AWS CLI command.
Enterprise teams who want more hands-on support can work directly with our team through every step of migration. Reach out at sales@fil.one to get started.
Egress is any data transferred out of your bucket: to the internet, to another cloud, or to your own servers. On a paid plan there is no egress charge, subject to reasonable use, and there are no per-request charges either. The 30-day trial includes 2 TB of egress. Upgrade to a paid plan to keep downloading after that.
Training reads, restores, full scans and rehydration are what the storage is for, and they fall well within reasonable use. The reasonable-use policy covers cases object storage is not designed for: CDN-like use cases, where egress runs at many times the amount stored, month after month. For those, the standard setup is to put a CDN in front of the Fil One bucket, using Fil One as the CDN origin. If a workload is heading toward that pattern, we will contact you first. Storage on a cross-connect in your own facility never touches the internet, so the policy does not apply there.
Billing is $5.99 per TB stored per month, with no fees for egress or API operations, subject to a $5.99 monthly minimum. Store under 1 TB and you pay the minimum; store more and you pay per TB for what you use.
Yes. Teams with predictable storage needs can talk to us about multi-year committed capacity. Talk to sales and we will put a quote together.
You choose when you create the bucket: Europe (France) or US East (Michigan), with more regions on the way. A bucket's region is fixed at creation, so data written there stays there. Each region has its own endpoint, and an access key is scoped to a single region.
Running a GPU cloud? We can also install storage directly inside your own data center. Host a zone.
Public buckets are not currently supported. To share individual files, you can generate a presigned URL from the dashboard or via the S3 API. This gives time-limited access to a specific object without making the entire bucket public.
Fil One is S3-compatible, so tools like rclone work out of the box. Point rclone at s3.eu-west-1.filonecontent.com with your Fil One credentials and sync your data across. If you need help with a larger migration, reach out and we'll guide you through it.
Not currently. Billing is in USD. If paying in FIL is a hard requirement, get in touch and we can explore options depending on your storage volume.
