Notes on speed, protocols, and shipping files.
Thoughts from the WarpSend team on building faster file transfer.
A brief history of fast file transfer (1971 — 2025)
FTP turned 54 this year. The story of how we got from RFC 114 to UDP-based congestion control running on Cloudflare's edge is shorter, weirder, and more reproducible than most people think.
IBM Aspera alternative: faster setup, lower cost
Aspera moves files. It also moves between $75K and $150K in licensing, infrastructure, and support. Here's an honest look at when Aspera is worth that — and when you should be looking somewhere else.
WarpSend vs WeTransfer: what's the difference?
WeTransfer changed dramatically after the Bending Spoons acquisition — quotas, retention, and pricing all moved against the freelancer. Here's an honest side-by-side, including when WeTransfer is still the right call.
How WarpSend achieves 618× faster than FTP
A detailed look at why FTP collapses across continents, why BBR doesn't fully save you, and how WarpSend's UDP engine, packet packing, and persistent connections actually deliver line-rate transfer over long-fat networks.
FTP is dead. Here's what to use instead.
FTP was specified in 1971 — six years before TCP. SFTP doesn't fix the underlying problem. Here's the protocol-level reason both fall apart on long-haul links, and what the modern alternatives actually do.
Introducing WarpSend
Most teams still ship hard drives, wait overnight for WeTransfer, or pay six figures for Aspera. We built a third option — fast enough to make couriers redundant, cheap enough that you don't need an IT project to deploy it.
