Launch a real endpoint
Harbor starts an embedded Rust HTTP server on loopback by default. Switch to LAN access only when your test devices need it.
Your S3 sandbox, docked on your Mac.
Spin up a private S3-compatible endpoint, create buckets, manage objects, rotate access keys, and expire test data without Docker or cloud accounts.
macOS 12+ · 100% local · No Node.js runtime
The whole server lives inside one app.
Cloud-shaped development should not require cloud-shaped setup.
Open the app. Copy the endpoint. Keep building.
Shape your test storage
Create buckets and folders, stream files in, download them, inspect metadata, and generate short-lived signed links from one table-first workspace.
Connect existing tools
Use AWS CLI and path-style S3 SDK clients with Signature V4 credentials stored safely in your macOS Keychain.
Local by architecture, not by promise.
Object bytes never leave your Mac. Metadata uses bundled SQLite, secrets use Keychain, and every stored object is mapped to a collision-resistant filesystem path.
