HushOS Drive - Your files all private

by•
HushOS Drive keeps your files private without changing how you work. Files, names, and previews are encrypted on your device. Organize with folders and tags, search locally, resume uploads, and preview photos, PDFs, videos, and documents in your browser. Share with people or send links with passwords and expiry dates. Versions and trash help you undo mistakes. Open source and self-hostable, or ready to use at hushos.com with 2 GiB free. Your files, your keys, your choice of where they live.

Hi Product Hunt, I'm Heet, the maker of HushOS. The goal is simple: make the private choice the easy choice. Your files should stay yours without making everyday storage feel like a security project. HushOS 1.0 starts with Drive. Upload, organize, preview, search, and share files in a familiar browser app. Files are encrypted on your device before they leave it. The code is open source, and you can use hushos.com or run the same app on your own server. The hosted free plan includes 2 GiB; paid plans add storage. This started with a prototype I built in 2023, including a protocol I wrote by hand. It worked, but getting from a working prototype to something I wanted people to trust meant revisiting the decisions underneath it. For the GPT-6 Astra Challenge, I used Astra as a coding partner throughout that process. We iterated on the product design and everyday interactions, revisited my original protocol, and worked through implementation details, performance, edge cases, and tests. The work was as much about questioning the old design as writing new code. That meant improving how keys are separated and wrapped, binding encrypted envelopes to where they belong, reserving storage before uploads, and making sharing and revocation actual key operations. We turned weaknesses from the prototype into explicit rules and tests, then kept iterating on how those rules felt in the interface. Astra helped me work across the UI, protocols, and implementation without losing sight of the whole product. Astra also caught issues I had missed. One example: the presence of a thumbnail could leak whether an encrypted file was media or another binary type. It helped me look beyond the encrypted contents and question what the surrounding metadata could reveal. We also worked on performance as we iterated, because a private drive still needs to feel fast in everyday use. The design documents and code are public so people can inspect the decisions. Drive is the first piece; messages, notes, and the rest of the suite are still ahead. I'd love feedback on what feels easy, what feels confusing, and what would stop you from using HushOS for your everyday files. If you look through the protocol or self-host it, I'd especially like to hear what you find. Try it: Code:

Great work, signed up and better than gdrive!

Fast and easy encrypted sharing..

Love it!

A bit more about where HushOS goes after Drive.

The goal is to make the private choice the easy choice across everyday work and life. Drive is the first piece, and it is what this launch delivers. Here is what we are working toward next:

Native mobile and desktop clients

We plan to launch dedicated mobile and desktop clients soon, so you can use HushOS beyond the browser. The aim is the same familiar experience and privacy by default, in apps built for the devices you use every day.

More productivity apps

We plan to build out the suite with notes, documents, messaging, and other everyday tools. We want these to work together under the same approach to privacy, rather than making you learn a different security workflow for every app.

Plug-and-play SDKs for developers

We also plan to make the underlying capabilities available to other developers. The goal is SDKs that make it easier to add end-to-end encryption to an app while using HushOS's cloud infrastructure. Developers should be able to focus on their product while integrating client-side encryption and the infrastructure behind it. This is planned work; the developer SDKs are not part of today's release.

An E2EE chat app

A chat app is coming soon. We want to bring conversations from other apps into one place, starting with WhatsApp, Telegram, and Signal, while preserving end-to-end encryption. Preserving E2EE across those integrations is a core design goal. We plan to publish how each integration handles messages and encryption as the design develops.

Drive is available today, and these are the next steps. HushOS is open source, and we will keep sharing the designs and releases as the project grows.

Which would be most useful to you first: native clients, unified chat, another productivity app, or the developer SDKs?

HushOS handles private file storage and sharing. GPT-6 Astra was my development and review partner, not a service that reads users' files. Starting from my 2023 prototype and handwritten protocol, we iterated on the interface, protocol design, implementation, performance, edge cases, and tests. Astra also found issues I had missed: for example, thumbnail presence could leak whether an encrypted file was media or another binary type. That helped me examine metadata leakage alongside encryption and everyday usability. The result is HushOS 1.0: an open-source, self-hostable drive with on-device encryption, previews, search, sharing, and recovery. The code and design documents are public for inspection.
