A cross-platform AWS S3 client for Mac, Windows, and Linux
Buckets by ServerlessCreed is a cross-platform desktop S3 client built for engineers who live in AWS. Browse buckets, generate presigned URLs, edit policies, and switch profiles in one place, with every workflow a click away.

Why developers pick Buckets by ServerlessCreed as their S3 client
Buckets by ServerlessCreed is built around how engineers actually work with AWS — multi-account SSO, IAM-aware tools, and focused desktop workflows.
Built for S3 from the ground up
Every screen, shortcut, and feature is designed for S3 semantics — versioning, storage classes, requester-pays, server-side encryption.
AWS SSO & IAM Identity Center
Sign in with your existing AWS SSO profile. Keep each account in its own tab and switch in a click. Use short-lived credentials; expired sessions may require sign-in.
Visual bucket policy & CORS editor
Stop writing JSON by hand. Build bucket policies and CORS rules with a typed UI that validates as you go, then review the generated JSON before you save.
AWS SDK code generation
Right-click an object and copy the AWS SDK code to fetch, sign, or stream it — in TypeScript, JavaScript, or Python. Useful for one-off scripts and pasting into PRs.
Multi-profile, multi-region
Pin frequently-used profiles, jump between regions, and view objects across accounts in a single window. Ideal for multi-tenant or staging/prod splits.
Local-only credentials
Your AWS keys stay on your machine. Buckets by ServerlessCreed never proxies traffic — every API call goes directly from your computer to AWS over TLS.

Frequently asked questions
What is an AWS S3 client?+
An AWS S3 client is a desktop application that lets you browse, upload, download, and manage files in Amazon S3 buckets from a native desktop app. A good S3 client gives you a desktop GUI, drag-and-drop file transfer, multi-profile support for several AWS accounts, and tools like presigned URL generation and bucket policy editing.
What can I do with Buckets by ServerlessCreed?+
Buckets by ServerlessCreed is purpose-built for AWS S3. Browse and transfer files with drag and drop, sign in with AWS SSO and IAM Identity Center, switch between profiles, generate presigned URLs, edit bucket policies visually, generate AWS SDK code, and estimate storage costs, all from one desktop app.
Does Buckets by ServerlessCreed work on Mac, Windows, and Linux?+
Yes — Buckets by ServerlessCreed supports macOS, Windows 10/11, and Linux. The Windows edition is installed and updated through Microsoft Store; macOS and Linux use platform-specific packages. All platforms share the same product features and license.
Do I need AWS credentials to use Buckets by ServerlessCreed?+
Yes, you need AWS credentials to connect to your S3 buckets — either an access key/secret pair, an AWS SSO session, or an existing AWS CLI profile. Credentials are stored locally on your machine and never sent to Buckets by ServerlessCreed's servers. All S3 traffic goes directly between your computer and AWS.
Is there a free trial?+
Yes — every new install gets a fully-featured 14-day trial with no credit card required. The trial unlocks every feature on every supported platform. After the trial, you can subscribe ($5/month or $49/year) or buy a lifetime license ($99 one-time).
Can I generate presigned S3 URLs with Buckets by ServerlessCreed?+
Yes. Buckets by ServerlessCreed has a built-in presigned URL generator — pick the object, set the expiration, and copy the download URL. Temporary AWS credentials can expire before the selected link lifetime. The generated URLs are standard AWS-signed URLs you can share with anyone, including users without AWS accounts.
