Free alternatives to Amazon S3

2 services, checked weekly

Amazon S3 is paid per GB stored and transferred, with only a time-limited free tier for new AWS accounts. These storage services keep a free amount of storage every month, and both speak the S3 API, so existing S3 code and tools keep working.
