For teams on AWS S3 looking to reduce storage costs

    Leaving S3 is a config change,
    not a rewrite.

    Point your existing S3 tools at Fil One. $4.99/TB flat, no egress. Same SDK, same API, lower bill.

    Change the endpoint. Nothing else.

    Fil One implements the S3 API. The code that works on AWS works here — PutObject, GetObject, ListObjectsV2, multipart upload, presigned URLs.

    Python (boto3)

    # Before — AWS S3
s3 = boto3.client(
    "s3",
    region_name="us-east-1",
)

# After — Fil One (no other changes)
s3 = boto3.client(
    "s3",
    endpoint_url="https://eu-west-1.s3.fil.one",
    aws_access_key_id=os.environ["FIL_ACCESS_KEY"],
    aws_secret_access_key=os.environ["FIL_SECRET_KEY"],
    region_name="eu-west-1",
)

    Node.js (@aws-sdk/client-s3)

    // Before — AWS S3
const s3 = new S3Client({ region: "us-east-1" });

// After — Fil One
const s3 = new S3Client({
  endpoint: "https://eu-west-1.s3.fil.one",
  region: "eu-west-1",
  credentials: {
    accessKeyId: process.env.FIL_ONE_ACCESS_KEY,
    secretAccessKey: process.env.FIL_ONE_SECRET_KEY,
  },
});

    What is compatible

    PutObject, GetObject, DeleteObject, HeadObject, CopyObject, ListObjectsV2, CreateBucket, DeleteBucket, multipart upload, presigned URLs. Standard Auth v4 signing. For a full compatibility list, see docs.fil.one.

    10 TB stored, 10 TB read/month. What changes.

    AWS S3 Standard us-east-1 Q2 2026: $0.023/GB storage, $0.09/GB internet egress, $0.0004/1K GET. Computed from stated inputs — 10,240 GB × $0.023 = $235.52 storage; 10,240 GB × $0.09 = $921.60 egress; 1M × $0.0004/1K = $0.40 ops. Fil One: 10 TB × $4.99 = $49.90, egress $0, ops $0.

    S3 parity. Lower bill.

    The same tools, the same APIs, the same integration patterns. The line items that dominated the invoice do not exist here.

    Full S3 API parity

    PutObject, GetObject, DeleteObject, ListObjectsV2, multipart upload, presigned URLs, and bucket operations all work as on AWS. Existing S3 code connects without modification.

    No egress on reads

    Every GET request on AWS charges $0.09/GB out to the internet. On Fil One, reads are included in flat storage. The SDKs behave identically; the bill does not.

    Predictable flat cost

    Storage at $4.99/TB. No egress, no per-request fees, no storage tier waterfall. The line item you plan for is the line item that ships.

    Recurring integrity verification

    Every object is verified approximately every 24 hours. Data does not silently corrupt or disappear without detection — no extra configuration required.

    One rate. $4.99/TB/month.

    Storage. That is the whole bill. No egress fees, no per-request charges. The S3 code carries over; the invoice does not.
