Question 1

How do I connect my S3 bucket?

Accepted Answer

Simply go to the dashboard, click 'Add Bucket', and enter your S3 credentials. Your credentials are encrypted at rest and never leave the server.

Question 2

What's the difference between Free and paid plans?

Accepted Answer

Free gives you 5 GB of encrypted storage with file uploads, S3 API access, file sharing, and 1 external bucket connection. Paid plans add more storage, higher bucket and API limits, and teams from Starter onward with no per-seat fees.

Question 3

Do I pay extra for teams or the S3 API?

Accepted Answer

No. S3 API, external buckets, and AgentBucket are included with plan-specific limits. Teams start on Starter; members share the owner's storage quota instead of being billed per seat.

Question 4

Can I mix my own buckets with Bucket0 storage?

Accepted Answer

Yes! All plans let you connect external S3-compatible buckets alongside Bucket0's managed encrypted storage.

Question 5

What is S3 API access?

Accepted Answer

S3 API lets you access your Bucket0 storage using standard S3-compatible tools like AWS CLI, SDKs, and apps like Cyberduck. Free plan includes 1 bucket, paid plans get up to 100 buckets.

Question 6

What is AgentBucket+?

Accepted Answer

AgentBucket is storage built for AI agents: they save, list, read, and delete files through a simple API or one-click MCP connector. On paid plans it becomes AgentBucket+, where files are automatically indexed so agents recall them by meaning across sessions, not just by filename.

Question 7

Will my data be used to train AI models?

Accepted Answer

No. We guarantee that your data will never be used to train AI models. Your files are yours alone.

Question 8

How are my credentials stored?

Accepted Answer

Your S3 credentials are encrypted at rest using AES-256-GCM before being stored in our database. They are only decrypted server-side when needed for operations.

Question 9

Is my data encrypted?

Accepted Answer

Yes. All files stored on Bucket0 are encrypted with AES-256 before being stored. Data in transit is protected with TLS 1.3.

Question 10

What plans does Bucket0 offer?

Accepted Answer

We offer four plans: Free (5 GB, 1 S3 API bucket), Starter ($7/mo or $5/mo annual with 150 GB, 10 buckets), Pro ($19/mo or $15/mo annual with 700 GB, 50 buckets), and Scale ($45/mo or $35/mo annual with 2 TB, 100 buckets).

Question 11

Are teams included on the free plan?

Accepted Answer

No. Teams start on the Starter plan. When you upgrade, members share your storage quota with no per-seat fees. Pro and Scale plans also include team chat.

Question 12

How do teams work?

Accepted Answer

You can create teams and invite members to collaborate on shared files. Team storage comes from the owner's plan quota. There are no per-seat charges. Pro and Scale plans also include team chat.

Question 13

Do you offer annual billing discounts?

Accepted Answer

Yes, annual billing saves you roughly 20% compared to monthly billing. You can switch between billing periods at any time.
