What Filestack is
Filestack provides tools and APIs to upload, transform, store and deliver content for applications. It offers file pickers for web, iOS and Android, plus client-side, server-side and REST APIs. URL-based image and document transformations cover more than 100 formats, and delivery uses a global CDN with smart caching and responsive images. Files can be stored in Filestack's S3 bucket or customer storage such as Amazon S3, Google Cloud Storage, Dropbox, Rackspace and Azure. The picker connects more than 20 upload sources, while security controls include signed policies, domain allowlisting, authentication signatures and secure transfer. Built-in AI features include virus and phishing detection, OCR, object detection, captions, sentiment and safe-for-work classification. SDKs are available for JavaScript, React, Angular, PHP, Python, Java, Ruby, Go and Swift. The free plan includes 1 GB bandwidth, 500 uploads, 1,000 transformations and 1 GB Filestack storage, with community support and a 20 MB file-size limit. Filestack says it is headquartered in San Antonio, Texas.
