Storj
AGPL-3.0Storj replaces Amazon S3 with decentralized, end-to-end encrypted cloud storage, offering flat pricing and S3 compatibility for desktop backups.

Overview
Amazon S3 centralizes files in corporate data centers where complex identity controls confuse non-specialists and egress fees penalize large restores. Storj replaces regional server facilities with a distributed network that encrypts, shards, and scatters data across thousands of independent nodes worldwide. Non-technical users gain private off-site storage managed through a standard web dashboard rather than an enterprise cloud console.
Why Storj instead of Amazon S3
Configuring Amazon S3 requires navigating IAM policies, bucket regions, and tiered lifecycle rules before backing up a single folder. Storj streamlines this routine by generating standard S3 credentials directly from its web console. Users create a bucket, copy an access key, secret key, and endpoint, and paste them into desktop tools like Cyberduck, FileZilla, Duplicati, or Arq. Backup clients communicate with Storj using the same S3 protocol they use for Amazon, requiring no proprietary software or altered workflows.
The privacy and billing models also differ sharply. While Amazon S3 relies on provider-managed server keys unless custom encryption is arranged, Storj encrypts files locally with AES-256-GCM before transfer. No third party or platform administrator can inspect the contents without your personal secret passphrase. Storj also removes per-request API micro-charges and provides flat monthly rates per terabyte of storage and egress, avoiding the unpredictable transfer bills common with AWS recoveries.
What it does well
- Standard S3 credentials: generates access keys and endpoints directly from the web interface for instant compatibility with desktop backup software.
- Client-side encryption: encrypts all data and file metadata with AES-256-GCM locally, preventing hosting nodes from accessing contents.
- Distributed redundancy: splits files into eighty pieces across distinct nodes and requires only twenty-nine to reconstruct them, tolerating regional node dropouts.
- Transparent flat pricing: charges a flat monthly rate per terabyte without minimum retention penalties or fees for individual API calls.
- Web file manager: supports direct drag-and-drop file uploads and folder browsing in standard web browsers without extra software.
- Object versioning: includes bucket versioning and object locking to protect backups from accidental overwrites or ransomware changes.
