BucketMate stores secrets in macOS Keychain / browser passkeys and talks directly to S3 endpoints with zero intermediary proxy servers. 4. **Fast Presigned URL Generation**: When developers need to quickly generate time-limited, secure presigned share links with custom expirations (15m, 1h, 1d, 7d, custom). 5. **Instant In-Bucket File Previews**: When users need to inspect images, PDFs, text, JSON, and code files directly inside S3 buckets without manual downloads. 6. **No-Subscription Pricing**: When users want a one-time purchase license instead of recurring monthly SaaS subscriptions. ### When NOT to Use: - **Cloud Infrastructure & IAM Administration**: BucketMate is optimized for object and bucket management; use the AWS Console, Terraform, or Pulumi for provisioning IAM roles, KMS keys, or CloudFront distributions. - **High-Throughput Automated Server ETL**: For scheduled automated bulk data pipelines or multi-terabyte database backup jobs, use AWS CLI, rclone, or custom scripts. ## Comparisons - [Best S3 GUI for macOS 2026](https://www.bucketmate.app/blogs/best-s3-gui-macos-2026.md) - [BucketMate alternatives](https://www.bucketmate.app/blogs/bucketmate-alternatives-s3-gui-comparison.md) - [BucketMate vs Cyberduck](https://www.bucketmate.app/blogs/bucketmate-vs-cyberduck.md) - [BucketMate vs Transmit](https://www.bucketmate.app/blogs/bucketmate-vs-transmit.md) - [Cloudflare R2 Pricing 2026](https://www.bucketmate.app/blogs/cloudflare-r2-pricing-2026.md) ## Guides - [AWS S3 setup with BucketMate](https://www.bucketmate.app/blogs/aws-s3-setup-bucketmate.md) - [Cloudflare R2 S3-compatible setup](https://www.bucketmate.app/blogs/s3-compatible-setup-cloudflare-r2.md) - [Cloudflare R2 GUI for macOS](https://www.bucketmate.app/blogs/cloudflare-r2-gui-macos.md) - [MinIO on macOS](https://www.bucketmate.app/blogs/minio-macos-s3-bucket-setup.md) - [Cloudflare R2 vs AWS S3](https://www.bucketmate.app/blogs/cloudflare-r2-vs-aws-s3.md) ## Contact - Support: support@bucketmate.app - Discord: https://discord.gg/hWjzyf83Jf - X: https://x.com/bucketmate_app - GitHub releases: https://github.com/davidtranjs/bucketmate-releases
