Subtle.sh – Zero-setup E2E encrypted messaging using OpenPGP and Soketi
Hey HN, I've been playing around with OpenPGP.js and Soketi lately and decided to build a simple E2E encrypted messaging app. It's called subtle.sh. The idea is pretty straightforward: you need to send a secret to someone, but you don't want to use Slack, email, or any other plain text medium. subtle.sh generates a fresh session with ephemeral keys, you share the link, and once the tab is closed, everything disappears. Some key points: - Zero setup required (no accounts, no installation) - E2E encryption using OpenPGP.js - Real-time messaging with Soketi (an open-source Pusher alternative) -…
Subtle.sh – Zero-setup E2E encrypted messaging using OpenPGP and Soketi launched on September 8, 2024 with 10 votes, #1,270 of 5,281 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Subtle.sh is a web-based encrypted messaging application that requires no account setup or installation. Users generate ephemeral sessions with OpenPGP.js encryption, share a link with recipients, and all messages disappear once the tab closes. Built with Next.js and React, it uses Soketi for real-time communication and is fully self-hostable. It is designed for anyone needing to securely send secrets without relying on email or chat platforms.

Burner NoteJan 2026 · burnernote.com · ▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.

An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf2024 · github.com · ▲66This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

Talanoa▲341Hi 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…
