S3-Compatible object storage with no egress fees.

Filebase delivers familiar S3 semantics on top of a globally distributed CDN — at $0.015 per GB-month, with no charges for outbound egress. Use the AWS SDK, AWS CLI, or any S3 client you already know.

Why developers pick Filebase

• No egress fees. Outbound bandwidth is free. You pay only for what you store.
• Drop-in S3 compatibility. Point any AWS SDK or S3 client at s3.filebase.io and it just works — same authentication, same operations, same response shapes.
• Aggressive edge caching. Filebase operates its own global CDN, with hot objects served from edge points-of-presence close to your users.
• Encrypted by default. Server-side encryption at rest and TLS in transit. No flag to flip.
• Predictable pricing. $0.015 per GB-month for storage. See the pricing page for full details.

Endpoint and region

Every Filebase S3 request uses the same endpoint and region. If you've used AWS S3 before, only these two values change:

Setting	Value
Endpoint	https://s3.filebase.io
Region	auto
Signature version	s3v4

Drop those into any AWS SDK and continue using the operations you already know.

AWS SDK for JavaScript v3

import { S3Client } from '@aws-sdk/client-s3';

const s3 = new S3Client({
  endpoint: 'https://s3.filebase.io',
  region: 'auto',
  credentials: {
    accessKeyId: process.env.FILEBASE_KEY!,
    secretAccessKey: process.env.FILEBASE_SECRET!,
  },
});
