Manage cloud storage without the CLI
AWS S3 and DigitalOcean Spaces are object storage services. The AWS CLI is powerful but requires installation and terminal familiarity. A web-based S3 manager offers:
- Browse buckets — navigate folder-like structures.
- Upload files — drag-and-drop or select files.
- Download objects — fetch any file directly.
- Delete or move — manage objects without CLI commands.
- Credentials encrypted — your AWS keys stay local, never exposed to servers.
S3 bucket structure
S3 is flat object storage, but you can use / in object keys to simulate folders:
`
bucket-name/
uploads/
image.jpg
logs/
2026-01/
access.log
`
S3 Drive displays this as a tree, like a file system.
Getting AWS credentials
1. Open AWS IAM console. 2. Create an access key pair (Access Key ID + Secret Access Key). 3. Optionally attach a policy limiting access to specific buckets. 4. Paste credentials into S3 Drive (encrypted locally).
Never share or commit credentials. Use IAM roles in production.
Features
- Multi-bucket support — manage multiple buckets from one dashboard.
- Drag-and-drop upload — works in modern browsers.
- Batch operations — delete multiple objects at once.
- Object metadata — view size, modified date, and storage class.
- Signed URLs — generate temporary public links (optional).
Frequently asked questions
Is it safe to paste AWS credentials into a web tool?
MyDevTools encrypts credentials with AES-256 in your browser before sync. For maximum security, use AWS temporary credentials (STS) or bucket-specific IAM policies.
Can I upload large files?
Browser uploads are limited by RAM. For large files, use S3\'s multipart upload via the CLI or AWS Console.
Does S3 Drive work with other cloud storage?
DigitalOcean Spaces is S3-compatible. Any S3-compatible service should work.
