Comparison
BasiX or a developer upload service like UploadThing?
UploadThing is built for TypeScript web apps: you declare file routes on your server, drop an upload button into your front end, and it handles the transfer. BasiX is an HTTP API that any language can call — Lua, PHP, Python, a shell script — with a CDN, thumbnails, logs and databases in the same account.
Where UploadThing is ahead
In a Next.js or React app written in TypeScript, typed file routes and a ready-made dropzone remove most of the upload code you would otherwise write. If that is your stack and your files are not only media, it is a very direct fit.
Where BasiX fits
When uploads come from somewhere other than a TypeScript front end: a game server, a Discord bot, a PHP site, ShareX, a cron job. One multipart POST with an API key, or a presigned URL handed to the client, and the answer is a CDN address that can be resized from the URL.
Questions
Yes. Your server asks BasiX for a presigned URL and hands it to the browser, which posts the file to it. The URL works once and expires after 15 minutes.
