s3h.net
Developer tools benefit disproportionately from short names, because the address ends up typed into terminals, config files and documentation thousands of times. Every character is friction repeated.
S3H is three characters in the letter-digit-letter shape, and the S3 opening carries an immediate association with object storage for anyone working in cloud infrastructure. That suits a storage tool, a backup service, a data transfer utility, a CLI product, or an API host.
The .net is native for this kind of product. No infrastructure buyer has ever discounted a service over the extension, and it reads as network and technical, which is what the buyer is.
Outside the technical reading it’s simply three characters, from a set fully allocated for decades.
Clean, fast to type, listed now. Offers welcome.
