Filestack Alternative

Filestack bundles a lot into one product: a drop-in upload widget (file picker with sources like Google Drive, Facebook, and webcam), an intelligent ingestion network, on-the-fly transformations — image processing, document conversion, even video manipulation — and content delivery. The pricing reflects that surface area. Plans start around $69/month and scale through Grow and Scale tiers, and the meters that drive your bill are uploads, transformations, outbound bandwidth, and storage, each counted separately.

That is a fair trade if you genuinely use the picker UI and the transformation pipeline. But a large share of teams reach for Filestack, ship the widget, and later realize they were paying for an upload SDK and an image pipeline when all they needed was durable storage and a fast URL. files.link is built for that narrower job. You own the upload UX completely — a native input type="file", a dropzone, or your framework's form handling — and call a small REST API underneath.

The whole integration is three HTTP calls with your raw API key in the Authorization header (no Bearer prefix): POST /v1/files/{folderId} returns { success, urls:[{ url, id }] }; PUT the bytes straight to that presigned url; POST /v1/files/confirm-upload with { ids:[id] } finalizes and hands back a permanent CDN URL. Because step one is a presigned PUT, large files stream directly to storage instead of proxying through your server or a vendor's ingestion layer.

Public files are served over a global CDN; private files have no public URL and are reached through short-lived signed URLs (10-minute expiry) your backend mints per request. The honest omissions: files.link does not ship an upload widget, and it does not transform, resize, convert, or moderate files on the fly. If your product leans on Filestack's transformation URLs or its multi-source picker, those are real features you would be giving up — keep Filestack, or pair files.link with a dedicated transformation service.

What you gain is a frontend with no third-party widget in the bundle, one upload contract that runs identically from a browser, a Node backend, or curl, and prepaid credits covering storage and delivery together instead of four usage meters you reconcile after the fact.
