Sasha: a fast dual-pane file manager in Rust & Svelte
Hey everyone,
I've always wanted a file manager that's both blazingly fast and actually pleasant to look at and use every day. Explorer lacks basic power tools, and existing alternatives often feel bloated. So I built Sasha, powered by Tauri v2, Rust, and Svelte 5. AI was used heavily in the process, there's no reason to lie.
My goal was to make it incredibly snappy while bundling all the daily utilities you normally need 10 different background apps for.
Here is the quick rundown of what’s inside:
The Workflow: Dual-pane layout with tabs, 5 view styles, pinned files, smart folders, and color tags. It includes a Stash Queue (pick files from multiple folders and paste them all at once), Folder Sync, word-level File Diff, Flat View, and an Auto-organizer for messy folders. Plus, an integrated drop-down Terminal that automatically cds to the folder you're browsing.
Search & Performance: Sasha installs a dedicated, lightweight background service that indexes over 1M files in ~1 second. It powers the global search modal (Ctrl+F) with instant as-you-type results, accelerates whole-disk space analysis, and calculates folder sizes, while idling at just ~2 MB of RAM.
17 Built-in Viewers (Press Space or Shift+Space to pop out): Preview and edit almost anything natively. It handles images (decodes PSD/TIFF and includes a multi-layer editor), videos (includes a timeline editor to trim/export clips), an audio capsule player in the status bar, Office docs, spreadsheets, PDFs, EPUBs, Comics, Code/MD, 3D models, SQLite DBs, GPS tracks, Fonts, and SSL certs. You can also peek inside archives or 1-click mount disc images.
Power Utilities: Disk space analyzer, on-the-fly SHA-256 checker, batch renamer, batch image resizer, and dedicated batch converters for audio, video, and images.
Customization: Theme selector with 21 built-in presets, a visual Theme Studio (supporting custom image wallpapers, live looping video, and interactive web/shader backgrounds), the community Theme Hub, and 10 languages.
Trial: 7 days unrestricted. Once expired, nothing is disabled; you can keep using it freely with a WinRAR-style pop-up unless you decide to buy a license.
It’s available today for Windows 10/11 (Linux build is coming soon).
The first public build (v0.1.0) is up for download here: Github
I'd love to get your honest feedback, bug reports, or feature requests.
