Easy S3 Access for Teams
Share S3 files with humans and AI agents.
Your team, and now your AI agents, need to browse, upload, or download files from S3. You need to give them access without handing out your cloud credentials.
quickS3 is a web UI and MCP server that connects to your buckets. You invite users, connect agents like Claude Cowork or ChatGPT Work, set per-folder permissions, and audit everything.
Works with Amazon S3








Built for teams, not IAM experts
Share access to buckets safely: invite teammates by email, connect AI agents over MCP, limit everyone to specific buckets and folders, and see who did what, without handing out admin keys.
Role-Based Access Control
Give teammates the right level of access without exposing IAM complexity. Allow a bucket or folder prefix, then carve out a narrow deny exception when needed. A deny always wins across assigned roles.
Audit Logging
See who accessed what and when. Short retention keeps storage lean while providing accountability for small teams. It answers 'who downloaded that file?' without enterprise overhead.
AI Agent Access over MCP
Connect Claude Code, Codex, Claude Cowork, or any remote MCP client to your buckets. An agent gets only the roles you delegate, nothing more: the same bucket and folder rules, the same deny-wins checks. Files move directly between the agent and your storage provider, never through quickS3. Every action shows up in the audit log tagged as agent activity, and you can revoke access at any time.
Magic Link Authentication
Passwordless login via email. Users click a link, no passwords to manage or forget. Easy access for teammates who aren't tech-savvy, with no separate account to create.
S3-Compatible Storage
Works with AWS S3, DigitalOcean Spaces, Backblaze B2, MinIO, and any S3-compatible provider. Static tokens stored encrypted at rest. Your data stays in your bucket. quickS3 is just the gateway.

FAQ
Is quickS3 a storage system like MinIO?
No. quickS3 is a hosted UI layer on top of your existing S3-compatible storage. You get a friendly interface, roles, and audit logs—we don't run or replace your buckets.
Is quickS3 the same product as ezS3?
Yes. ezS3.net is becoming quickS3.com. It's the same product and team; we're moving to a clearer name and domain. If you followed an ezS3 link, you're in the right place.
Does quickS3 copy or store my data?
No. Your objects stay in your bucket. quickS3 connects to your storage so your team can browse, upload, and download with the permissions you set.
How do permissions work?
Use allow rules for a connection, bucket, or folder prefix, then add narrow deny exceptions when needed. A deny always wins across a person's roles.
Can I limit access to just one folder?
Yes. Use a folder prefix (e.g. /logs/ or /brand/). People only see and act on objects under that path.
Can AI agents use quickS3?
Yes. quickS3 is a remote MCP server, so clients like Claude Code, Codex, and Claude Cowork can connect to it. You authorize the agent in your browser and pick which of your roles it may use; it gets those roles' bucket and folder permissions and nothing else. Files transfer directly between the agent and your storage provider, actions are logged as agent activity, and you can revoke access at any time. Agents don't count as users.
What storage can I connect?
AWS S3, Cloudflare R2, Backblaze B2, DigitalOcean Spaces, Wasabi, Azure Blob, MinIO, and any S3-compatible API. Add a connection in Settings with your access key and bucket; your data stays in your bucket.
Do I need to move or change my bucket?
No. Use your existing bucket and provider. Add a storage connection in quickS3 (access key and optional bucket scope); your team gets the UI without moving any data.
Why not share the AWS console or presigned URLs?
Console access is all-or-nothing and hard to audit per person. Presigned URLs are one-off and don't give a persistent, role-based view. quickS3 gives each person limited, audited access so you don't over-share credentials.
How long are audit logs kept?
14 days. Enough to answer "who did what" without long-term retention; longer retention may come in a future plan.
How do users sign in?
Magic links by email by default, with Google OAuth available. Teammates sign in to quickS3 only—they never see your storage credentials.
Security
quickS3 keeps your files secure with short-lived access URLs and activity logging for every action. Your access credentials (keys) stay encrypted at rest on our servers and are never sent to or stored in browsers. This approach works well for most teams, but if you need SOC2 compliance, full audit trails, or temporary credentials instead of long-lived tokens, we'll show you exactly what to consider before you connect your storage.
