Make incoming data useful sooner.

Land CSV, JSON, images, and archives in River, preview them in place, and mount them into the runtimes that need them. Flip a bucket public and it becomes static hosting with its own domain.

The problem

The data you need often arrives as a file. Getting it into the right environment means manual uploads, temporary buckets, and undocumented steps.

The River approach

River gives files a managed home, previews them in the workspace, and mounts them into notebooks and services at predictable paths — with public hosting when a site needs to ship.
