Comparison · AWS S3

Best AWS S3 alternatives

AWS S3 is the object-storage target all seven tools on this page are listed against, and three of the seven are marked open source. Uploadthing is file uploads for TypeScript developers, described as dead simple, with a generous free tier listed, MinIO is high performance object storage released under GNU AGPLv3, with self-hosted free and enterprise pricing listed, and Cloudflare R2 is S3-compatible object storage with zero egress fees, listing a free tier of 10 GB of storage a month, though enabling it goes through a checkout that needs a payment method on file. Tigris is globally distributed S3-compatible object storage with zero egress fees, listing a free tier of 5 GB of storage a month, though as a young service it had 16 status incidents between July and October 2026, and Backblaze B2 is pay-as-you-go cloud storage without vendor lock-in, listing a free tier of 10 GB of storage a month at $6.95 per TB after the free allowance. SeaweedFS is a simple and highly scalable distributed file system, listed as free open source, though its day-2 features like recovery and erasure-coding repair are paid Enterprise, and Garage is an S3 object store so reliable you can run it outside datacenters, listed as free open source, though it covers a narrower S3 surface with no bucket policies, ACLs, or versioning, so it is not a MinIO drop-in.
