What Filestack is
Filestack provides developers with tools and APIs to upload, transform, store, and deliver content in applications. Its file pickers support web, iOS, and Android, while client-side, server-side, and REST APIs provide additional ways to connect file workflows. URL-based image and document transformations support more than 100 formats; responsive images and a global CDN with smart caching support content delivery. Files can be held in Filestack storage or customer storage such as Amazon S3, Google Cloud Storage, Dropbox, Rackspace, and Azure. The picker connects more than 20 sources out of the box, including Google Drive, OneDrive, Box, Gmail, and Unsplash. Security features include signed policies, domain allowlisting, authentication signatures, and secure transfer. AI capabilities cover virus and phishing detection, OCR, object detection, captions, sentiment, and safe-for-work classification. Filestack offers SDKs for JavaScript, React, Angular, PHP, Python, Java, Ruby, Go, and Swift. The free plan includes 1 GB bandwidth, 500 uploads, 1,000 transformations, 1 GB Filestack storage, and one workflow, with community support. It limits individual files to 20 MB. Paid plans start at $69 a month for Start, with higher quotas on Grow and Scale; charges apply when usage exceeds plan quotas.
