Detailed Review

STRG sells S3-compatible object storage at $6.80 per TB per month. The pricing page says stored data, all egress and standard S3 API requests (uploads, downloads, listing, deletions and multipart uploads) are included, with no retrieval fees, no minimum storage duration and no minimum commitment on the self-service plan.

The first 10 GB per account are free. Prices are in US dollars and exclude VAT. On its own comparison table the vendor puts Wasabi at $7.99 and Amazon S3 Standard at $23.00 per TB per month, checked on 9 October 2026; those figures are the vendor's.

The imprint, terms and privacy policy name Stack Holdings GmbH in Vienna as the operator and data controller. The terms are governed by Austrian law, with the courts in Vienna competent for business customers.

Buckets live in one of two regions, Amsterdam (EU-Central) or Reston, Virginia (US-East), chosen per bucket, and the site says objects stay in the selected primary region unless replication is switched on. Object Lock is available in both regions.

The homepage states a design durability of 11 nines, and adds that contractual service levels are agreed separately; the terms say there is no uptime promise unless a written service level agreement says otherwise. STRG also runs an MCP server so AI agents such as Claude or Cursor can create buckets and manage objects with OAuth sign-in.

What STRG does well

  • One price per TB with egress and standard requests included
  • Amsterdam region with Object Lock available
  • Austrian operator under Austrian law
  • No minimum storage duration or retrieval fee
  • MCP server for AI agents

Where STRG falls short

  • Prices published in US dollars
  • Only two regions, one of them in the US
  • No certification listed on the pages read
  • No uptime commitment unless a separate SLA is signed

Standout feature. STRG is the only provider on the list that ships an MCP server for AI agents next to its S3 endpoint.
