Show HN: Port Messenger – Solving spam by removing public identifiers

by labadal on 5/26/25, 4:58 PM with 1 comments

With the rise in AI-driven spam, scams, and unchecked data aggregation, Port aims to solve this privacy nightmare upstream.

We got rid of identifiers — phone numbers, usernames, even high-entropy IDs — and what’s left is a messaging app that does everything, while still respecting your privacy and time. You can learn more about our protocol here: https://portmessenger.com/port-protocol-v1 .

Don’t worry, we didn’t reimplement a crypto library. We built end-to-end encryption with OpenSSL at the core. We’re actively improving our docs, cleaning up bad choices and everything else before we publish our source code so you can see how we did it!

Please check it out and let us know what you think. Any feedback goes a long way!

    I am only aware of one other chat app that doesn't use public identifiers: <https://github.com/simplex-chat/simplex-chat/>. I hope more chat apps adopt this, because it's absolutely necessary to maintain sanity online in the long-term.

    FWIW, it's better to release source code early than to make it perfect. No rational person will judge your code quality; a rational person would just submit pull requests.
