Products that do what Capsule – E2E encrypted file sharing does
Capsule started as a basic HTTP server to teach myself Rust. Then I kept going, and it turned into the first full-stack thing I've fully shipped: a Rust/Axum server, a Rust CLI, an Android app (my first, same story as the Rust one), and a fully featured web UI. It quickly grew as I realized I could solve my file transfer problem by turning a basic webserver into an actual daily use tool. Entire project is open source, code can be found at: https://github.com/withcapsule/ Would love to hear anyone's thoughts on this.

I reposted, since i forgot the Show HN prefix. When I looked at self-hosted options, true E2EE turned out to be surprisingly rare. Most solutions rely on disk encryption, which only protects against physical theft, not server compromise or admin access. So I built Agam Space, my attempt at a self-hosted alternative to Mega or Proton Drive. It uses proper zero-knowledge encryption. Files are encrypted in the browser, and the server only stores encrypted blobs. Admins literally cannot access the files. It’s still in early beta, with very basic functionality and no professional security audit…

Recently I've been playing with an idea of a file server on my Android phone, with a web browser access. I wanted to replace: - AirDroid - sending files to my own PC or laptop. - ShareIt - sending big files over the local network to my family devices. - Dropbox - sharing select files with other people over the Internet. Requirements I had in mind: - end-to-end encryption, no sign ups, no accounts, no passwords - local connection if devices are on the same network - asynchronous access, server should work seamlessly in the background This week I finally managed to stitch the pieces together…

I built this because I am perpetually drowning in file transfer hell. As a systems engineer, I am constantly moving massive files. Whether it's getting new releases of custom ISOs to clients, downloading entire filesystems to spin up clones, or uploading massive support packages to L3. I always have to get something to somebody. Usually, it's something large that lives on a headless server. I can't tell you how many times I've modified my 'clone' script to tar most of a filesystem over ssh ("hello --exclude, my old friend...") just to get 10GB that someone will need for two days. Tedious is…

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

Heya! We're longtime lurkers and do sometimes post, today however I want to present to you with the fruits of almost 4 years of work, hacking, designing, physically building (for the record: 2 years full time). We'd love to get some feedback from you guys and feel free to give us any hints on what we could/should change, or any opinion on whether you think that'd be something you'd use. protonet.info So here's our rough plan: We love the web and the possibilities it gives us, we also love the way the cloud allows us instant and ubiquitous access to our data and apps. Now what we don't like…

Hey HN, We’ve built new.space, a privacy-focused, end-to-end encrypted platform for secure collaboration and sharing. Key features: * E2EE: Files, notes, and links are encrypted before leaving your device. We have no access to decryption keys. * No sign-up: Use anonymously or create an account. * Real-time collaboration: Instant updates on web and iOS. Check it out at https://new.space or try our iOS app (https://new.space/app). We’d love your feedback and are happy to answer any questions you might have. -- Nathan P.S. Use code HACKTHENEWS for an extra 4GB storage.…

After a lot of work, I'm proud to show HN my first real "startup idea". HN has been a real inspiration to me. Attach.io allows users to upload files up to 2GB (soon to be 8GB) and share them with others. Attach.io offers the regular file for download, and also if possible, an alternative preview version, so users can view files on their iPad for example. PSD files get converted to PNG AVI, WMV etc... to MP4 EPS/AI to PDF DOC(X), PPT(X) etc... to PDF This is a sneak preview, and is not 100% complete. Things I still have on my ToDo list: Allow users to email link to others, currently they have…

Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

I've created a quick application that stores data in IPFS (http://ipfs.io) which is a distributed web implementation. It's working as expected, paste some content, get a hash in the url and send to a friend. The content will be there forever and distributed to peers that asks for it. Demo: http://ipfsbin.xyz/#QmXdMvJaRrSTCAcDFMZLUFfm9uGK6Wq7qEVcwbvaQRxq8x This have a couple of advantages, mainly that the same content would have the same hash, meaning that things wouldn't be duplicated. Source is available for people interested in that here:…

I've been self-hosting https://privatebin.net for a long time now but there were some annoying issues: no way to turn off encryption, API is complicated, no raw support on the page directly and worst of all: no keyboard shortcuts. I've looked at a bunch of other OSS solutions and all of them (atleast the ones I could find) didn't really have all the features that I needed. So I made this. Optional E2E encryption with optional password protection, keyboard shortcuts (kinda a WIP), simple-ish REST-ish API for making CLIs, direct raw file display & download (with optional server-side…

Magic Wormhole is great but requires a CLI or app. I put a full wormhole-rs client in the browser via WebAssembly so you can send E2E encrypted files to anyone — interoperable with all standard wormhole CLIs. Drop a file, get a code, other person opens the link or types wormhole-rs receive . SPAKE2 + NaCl encryption happens client-side, the server only bridges WebSocket transit. Built this as an experiment with Claude Code + gstack. All code written by Claude. Single Rust binary, vanilla JS, no framework. https://wormhole.page…

Hey HN, Along with a handful of friends, I've been working on a note taking platform for the last couple years. We created a 2 minute pitch of our platform, if you'd prefer to read, maybe you'd want to checkout our README: https://github.com/lockbook/lockbook. If you don't want to do either of those things I'll try to summarize some of our core values: - everything end to end encrypted - open formats: markdown and svg - strong offline support - everything open source - native apps where possible - rust where possible Some other stuff we're proud of: - we have a CLI which…

I thought it would be great to share code snippets without saving them on a server, so I created http://mem.pe It allows you to paste code and save it in your browser's local storage. When you share the URL of the pasted code, other people will connect to it via web sockets. For example, this http://mem.pe/#sge/5 you will be pulling from my browser. I'll keep it open for a while. If you close the web app, your code paste will not be available for anyone to see, until you open the web app again. This is obviously, not suitable for using at forums and other places…

I am a software engineer working alone on a passion project, a website that helps you stay organized easily and efficiently. Headspace.io is a webmail, notepad, task list and calendar, all rolled into on. The basic premise is that any data in Headspace can be "tagged" and then all relevant information for a particular tag can be displayed in one screen. This is a pre-beta build and I'm hoping to get some early feedback from the wise and generous HN folks. Would you pay a small monthly fee ($5 maybe) for a service like this? http://app.headspace.io/ (This is pre-production so…
