Filestack

Filestack is a file handling service for websites and apps. It provides an upload widget, a processing API and a delivery network for files.

Developers add an uploader to a site with a few lines of code, then pull files from a local disk or cloud sources. Images, documents, audio and video can be processed through URL parameters or workflow chains. Files are delivered through a global CDN with signed URLs and access rules, so the same service handles ingestion and delivery.

• Drop-in uploader with 20+ sources
• Resumable uploads for unreliable connections
• Image, document, audio and video processing
• Signed URLs and access policies for delivery
• SDKs for JavaScript, React, Python and more

Development teams that want to add file uploads and media handling without building an upload service themselves. It suits web and mobile apps that accept files from users.

Pricing and plan details are on the company's pricing page. Check the usage limits for storage and processing before you launch, since these affect cost. The service runs on Filestack's own infrastructure, so you rely on its uptime and delivery network.
