Everything you need, nothing you don't

Blazing fast uploads

Upload files directly via multipart POST. No need for presigned URLs or complex SDKs.

CDN-ready URLs

Public files get a clean proxy URL you can use anywhere — images, videos, assets.

Private by default

Files are private unless you explicitly make them public. You stay in control.

API key auth

Generate scoped API keys for programmatic access from your CI, backend, or scripts.

Simple REST API

One POST endpoint with multipart form-data. Upload, get back file metadata.

Reliable storage

Store and serve your files with confidence.
