Move buckets. Not headaches.
Transferon copies objects directly between S3-compatible providers — verified, resumable, and encrypted in transit. Nothing routes through your laptop, and nothing lands on disk in between.
Works with the providers you already pay for
Any provider below can be a source or a destination. Credentials are used only for the transfer and are never stored longer than the job runs.
From first bucket to fully verified copy
No CLI to install, no SDK to wire up. Set both ends, preview what's moving, and watch it verify itself on the way out.
Connect the source
Point Transferon at the source bucket with scoped, read-only credentials. We only ever list and read.
Connect the destination
Same for the destination provider. Keys are held in memory for the life of the job and discarded when it ends.
Map & preview
Review object counts, size, and any naming conflicts before a single byte moves. Nothing starts silently.
Transfer & verify
Objects stream provider-to-provider in parallel. Each one is checksum-verified against the source on arrival.
The defaults are the safe choices
Checksum-verified
Every object is hashed and compared at the destination before the job marks it complete.
Read-only source keys
We ask for the narrowest permissions the transfer needs — never write access to your source bucket.
Resumable
A dropped connection picks back up where it left off — not from the first object again.
In-transit encryption
Every hop is TLS, end to end. Credentials and object data never touch an intermediate disk.
