Amazon S3 API Support for Backblaze B2 Cloud Storage Service

In plain words

Backblaze B2 Cloud Storage Service offers Amazon S3 API support, enabling developers to interact with B2's cloud storage using standard S3 commands and tools. This compatibility allows existing S3-based applications and workflows to work with B2 without requiring code changes. The service targets developers and organizations seeking cloud storage solutions that maintain S3 API compatibility while using an alternative provider to AWS.

  WinCse – Integrating AWS S3 with Windows Explorer2025 · github.com · ▲65

  I previously introduced WinCse on Hacker News (original post: https://news.ycombinator.com/item?id=43947599).

Object storages tested for compatibility: - AWS S3 - Google Cloud Storage - OCI Object Storage - Wasabi Hot Cloud Storage - Cloudflare R2 - Backblaze B2 - Storj DCS - IDrive e2 With WinCse, you can access and manage object storage directly from Windows Explorer as if it were local files.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
