# CloudShare App Simplifies S3 Bucket File Transfers on iOS New utility enables direct file uploads to personal S3-compatible storage via iOS share sheet. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-11-08 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/ac40abfa-745b-4835-ac40-c4c19b90e215 ## Direct S3 Integration CloudShare allows users to upload photos, videos, and documents directly to their own S3-compatible storage buckets. By integrating with the iOS share sheet, the app facilitates seamless transfers from native applications like Photos and Files. It supports various providers, including Amazon S3 and Cloudflare R2, without requiring additional third-party cloud subscriptions. ## Credential Security Management The application prioritizes user privacy by storing all connection settings and API credentials locally within the device's Keychain. Developer Anton Novoselov explicitly states that the app does not collect any user data. This local-first approach ensures that sensitive access keys never leave the user's iPhone or iPad during the configuration process. ## Background Transfer Mechanism CloudShare handles large file uploads in the background, allowing users to continue other tasks while transfers proceed. The system automatically employs multipart uploads for larger files, enhancing reliability. If a transfer fails, the app supports retries that reuse previously uploaded segments, provided the provider's upload session remains active and valid for continuation. ## Flexible Link Generation Users can generate both public and private links for their stored objects directly within the interface. Private links offer customizable expiration windows, ranging from one hour to seven days, providing temporary access control. For public sharing, the app allows users to connect an existing domain to their bucket for streamlined file distribution. ## Storage and Compatibility Requirements The app requires users to provide their own S3-compatible bucket, HTTPS endpoint, and specific API permissions for listing and reading files. Cloud storage is not included in the $3.99 purchase price. Users remain responsible for any bandwidth, request, or storage fees charged by their chosen cloud provider based on their usage. ## Operational Constraints Folder uploads are not natively supported; users must compress directories into ZIP files before initiating transfers. Additionally, public link functionality depends on the user having a pre-configured public bucket or domain. The app does not perform DNS configuration or modify existing bucket permissions, requiring users to manage their storage infrastructure independently. ## System and Hardware Needs CloudShare is optimized for modern Apple hardware, requiring iOS 17.0 or iPadOS 17.0 and later versions. While the app is designed for mobile devices, it also supports macOS 14.0 on systems equipped with Apple M1 chips or newer. The 3.9 MB utility also includes support for Family Sharing among six members. ## Strategic Utility Value By bypassing proprietary cloud ecosystems, CloudShare offers a specialized tool for power users who prefer self-hosted storage solutions. The app bridges the gap between mobile convenience and professional object storage management. It serves as a practical interface for those already maintaining S3-compatible infrastructure who need mobile-native access to their data. ## Sources covering this story - https://apps.apple.com/us/app/cloudshare-s3-file-sharing/id6823902669 — --- _Summary written by Brifing from the original reporting.
