24 alternatives to Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web
Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications.. Many open source alternatives exist, but the problem I kept running into was not a lack of good private messengers. Signal, SimpleX, and other projects already do important work The problem…
Ekko is a browser extension that adds post-quantum end-to-end encryption to existing messaging platforms like Instagram, WhatsApp, and Telegram Web. Designed for privacy-conscious users concerned about data harvesting… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

This 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 :)

Hello HN, I have been working on a desktop P2P messenger called Kiyeovo for the last ~8 months, and I just published its beta version. Quick backstory: It started out as a CLI application for my Graduate Thesis, where I tried to make the most secure and private messenger application possible. Then, I transformed it into a desktop application, gave it "clearnet" support and added a bunch of features. Short summary: The app runs in 2 completely isolated modes: - fast mode: relay/DCUtR -> lower latency, calls support - anonymous mode: Tor message routing -> slower, anonymous These modes…

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) -…

Hey HN, I have been working on a side project for the last 3 months, built around LangchainJS and pgvector. It now supports ChatGPT, Llama, Claude, and Bison models, and the bot can integrate with WhatsApp, Telegram, and Discord for now. I would really appreciate some feedback. Thanks! repo: https://github.com/n4ze3m/dialoqbase

When I first discovered WebAuthn in 2019 I imagined it being used for something like this, but never imagined something like the prf extension enabling true E2EE like this. Everything happens in the browser; there's no server used in any of this because to me that defeated the purpose. I also challenged myself to make a decent UX on top of this because what good is strong encryption if it's not usable? For best results make sure you're using Chrome 116 and a recent FIDO2 security key.
