Azure Blob Storage vs Tigris

Azure Blob Storage scores 75.7 (BB) on agent readiness against Tigris's 44.4 (E), and leads in 6 of 7 scored categories. Tigris leads on payments & pricing. Both do storage object.

Which one, for what

Azure Blob Storage BB

Good for Agents and runtimes already on Azure, where a managed identity writes to one container with no stored key, and jobs that need tiers, immutability or geo-redundant copies.

Ahead on

  • Reliability, 88 against 35
  • Schema & documentation, 85 against 50
  • Agent ergonomics, 84 against 53
  • Security & auth, 81 against 51
  • Transparency & trust, 80 against 48

Also in its favour

  • Agent-ready, a grade of BB or better
  • No incidents deducted, where Tigris loses 3 points for them

Watch for

Shared Key authorisation with the account's access keys is allowed until the owner sets AllowSharedKeyAccess to false

Tigris E

Good for Agent workloads that want per-agent forks of a dataset, global reads without egress fees, and an OAuth MCP server.

Ahead on

  • Payments & pricing, 30 against 20

Also in its favour

  • Runs on your own machine

Watch for

16 status incidents between 4 July and 2 October 2026, including outages in US regions on 31 July and 2 August

Verdicts

Azure Blob Storage

Microsoft Entra ID roles can be scoped to one container, and a user delegation signature hands out a link that expires within seven days. Account keys with full access stay enabled until the owner turns them off, request logs are off until configured, and an Azure account needs a person, a phone number and a payment card.

Tigris

No egress fees, and one endpoint (t3.storage.dev) with region auto for every location. 16 status incidents between 4 July and 2 October 2026, including outages in US regions on 31 July and 2 August.

Before you call either

Azure Blob Storage

  1. Request an Entra ID token for https://storage.azure.com/ and send it as a Bearer header with x-ms-version and x-ms-date. Put Blob also needs x-ms-blob-type: BlockBlob
  2. Ask for a Storage Blob Data role on the one container. Role changes can take up to 10 minutes to apply
  3. To share a file, call Get User Delegation Key, then sign a SAS with sp=r, spr=https and a short expiry. Treat the URL as a secret
  4. Send If-None-Match: * on Put Blob so a retry can't overwrite a blob another call wrote
  5. On 503 ServerBusy back off exponentially. After 500 OperationTimedOut check the blob's state before retrying, since the write may have succeeded

Tigris

  1. Point the AWS SDK at https://t3.storage.dev with region auto; the stdio MCP README still shows the older fly.storage.tigris.dev endpoint
  2. Ask for an access key with a ReadOnly or ReadWrite role on one bucket rather than an org-wide key
  3. Keep presigned URLs short; Tigris accepts up to 90 days
  4. Don't call tigris_list_objects on a large bucket; it walks every object with no limit or prefix
  5. Use @tigrisdata/iam 2.6.0 or later before writing policies with conditions

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
