Questions

Can Stow take uploads from my users’ browsers?
Not directly. Stow keys stay on your server, so a browser upload goes through your own backend, which passes the file on. UploadThing is built for direct browser uploads, with components for most TypeScript frameworks.
Does UploadThing have search?
Its docs describe listing files by id and key, and recommend storing file details in your own database. Stow searches by tags, text, folder and type in one call.
Which costs less?
For plain storage, UploadThing: $10 a month for 100 GB. Stow Pro is $19 a month for 100 GB and 50,000 files, and adds search and automatic transcripts, summaries and tags.
Are files private?
In UploadThing, each app has a default (public or private), and private files are on paid plans. In Stow, you choose for each file when you upload it, on every plan.
