Better file uploads
for developers

Developers deserve better than S3. That's why we made UploadThing, the easier (and safer) alternative. From the button to the server, we've got you covered.

Documention Try It

Your Auth. Our Bandwidth.

The right balance ofsecurity and simplicity.

Authentication happens on your server, the upload happens on ours.

Server

Client

export const fileRouter = {
  imageUploader: f({ image: { maxFileSize: "4MB" } })
    .middleware(async ({ req }) => {
      // This code runs on your server before upload
      const user = await auth(req);
 
      // Throw to block uploading
      if (!user)
        throw new UploadThingError("Unauthorized");
 
      // Return metadata to client
      return { userId: user.id };
    })
    .onUploadComplete(async ({ metadata, file }) => ...),
} satisfies FileRouter;

I asked for a better S3 for years. UploadThing exists because we got tired of waiting.
