OtterRouteYour S3 buckets, on all your domains

A self-hosted gateway that publishes files from several private buckets through several domains, with a disk cache. Connect a storage, attach a domain and the file is online.

How it works

Installation

DNS and S3 providers

Many domains, many buckets

Routing by host and path prefix. Each bucket has its own credentials and its own cache, isolated from the others.

Disk cache

A single request to the storage per object even with many clients, streaming without loading files in RAM, stale copies served if the storage is down.

Domains really verified

The panel checks that DNS resolves and that a request to the domain reaches this node. If a domain stops working, it tells you.

Users, permissions and 2FA

Roles and scopes on actions, two-step verification with an authenticator app, activity log.

Statistics and Prometheus

Requests, cache hits, bandwidth, errors and latency in the panel, and the same metrics in Prometheus format.

Read-only, by design

Only GET and HEAD, credentials stay on the node and the query string never reaches the storage.
