- Current is a file-sharing website (soon an app) for sending files of any size without cloud storage.
- Built on iroh-blobs, it addresses slow cloud transfers and large file handling issues in DJ work.
- It includes a Rust core, TypeScript wrapper, and web/Swift UI, with features like progress tracking and cancellation.
- FFI challenges were overcome using a forked BoltFFI with customizations for WASM and async support.
- Memory optimization for large files in browsers uses IndexedDB to avoid loading entire files into RAM.
- Performance testing shows varied speeds, with web-to-web transfers at 75s for 500MB, and native transfers faster.
- Future plans include monetization for faster relay servers and potential open-sourcing.
