FAQ
Questions, answered.
It is Electron — with the engineering that usually goes missing. Listings are virtualized, so 100,000+ objects scroll smoothly instead of choking the window. The first page of any bucket paints from a single LIST request, and search runs against a local index instead of hammering the network. Fast is an architecture decision, not a framework one.
Focus is the feature. R2 has its own personality — zero egress fees, jurisdictions, custom domains, token-scoped credentials — and a generic S3 client papers over all of it. Targeting one provider is what makes instant first paint with a single LIST request possible.
Your credentials never leave your Mac. Tokens are stored in the macOS Keychain, and requests go directly from your machine to your R2 endpoint over TLS — no proxy, no middleman servers, no telemetry on your data. Revoke the token in Cloudflare and Buckotto is instantly blind.

Buckotto generates presigned R2 URLs locally — pick an expiry from 1 hour up to R2's ceiling of 7 days, and the link lands on your clipboard. Nothing passes through our servers, because there aren't any.
