Project ideas from Hacker News discussions.

E2E encrypted messaging on Instagram will no longer be supported after 8 May

📝 Discussion Summary (Click to expand)

1. Meta is pulling back on end‑to‑end encryption

“Meta starting introducing E2E messaging it was a huge push. I wonder why they're doing away with it.” – garbawarb
“It was for plausible deniability… now there's no downside and only upsides to spying on your users.” – gmerc

2. The real drivers are business and regulation, not privacy

“I assume they no longer believe the marketing benefits outweigh the downsides.” – john_strinlai
“…the product reason – AI features are fundamentally incompatible with E2EE.” – paxys
“They never did this for user privacy… they want to read your messages for training AI and for advertising.” – yobid20

3. Users feel betrayed and lose trust in the platform

“I’m not sure if anyone in HN has any useful advice… it’s another brick in the wall.” – everdrive
“The worst offenders on the internet have verified accounts and are public figures… getting rid of anonymity will do NOTHING to halt the march of internet‑fueled extremism.” – abnercoimbre
“People who otherwise would have gone their entire lives without ever hearing about encryption were exposed to the term and the marketing convinced them that encryption and privacy was a valuable thing.” – john_strinlai

4. Network effects keep people on the platform even without privacy

“Normal people don't choose a messaging app based on E2EE but based on whether their friends use it.” – gzread
“The only reason I can think of for this change is governmental pressure… but it’s also about the product.” – mvrckhckr
“If someone’s given the choice between Instagram and IRC, and chooses Instagram because they heard it has E2EE, that’s a loss.” – gzread

These four threads—Meta’s policy shift, the business/regulatory motives, the erosion of user trust, and the stubborn pull of social network effects—capture the core of the discussion.


🚀 Project Ideas

OpenDM: Plug‑and‑Play E2EE Library for Messaging Apps

Summary

  • Provides a lightweight, open‑source library that implements Signal‑style end‑to‑end encryption for any messaging app.
  • Eliminates the need for developers to build encryption from scratch, reducing bugs and adoption friction.
  • Core value: secure messaging becomes a default feature, not an optional add‑on.

Details

Key Value
Target Audience Mobile and web app developers building chat features.
Core Feature Signal‑protocol based E2EE with key management, forward secrecy, and optional backup encryption.
Tech Stack Rust (core), Swift/Java/Kotlin/JavaScript wrappers, gRPC/REST API.
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters lament the lack of open‑source clients: “E2EE on Instagram was never real, trustable E2EE.” OpenDM gives them a trustworthy base.
  • Developers can quickly add encryption to existing DMs, addressing the “opt‑in” frustration.
  • Encourages a broader ecosystem of secure messaging, sparking discussion on open standards.

DM Switcher: Automatic Secure‑Messaging Redirector

Summary

  • Detects when a platform’s direct messages are not end‑to‑end encrypted and automatically offers to switch the conversation to a secure alternative (Signal, Wire, etc.).
  • Works as a browser extension or mobile overlay, preserving the user’s social graph while enhancing privacy.
  • Core value: seamless transition to secure messaging without losing contacts.

Details

Key Value
Target Audience Privacy‑conscious users on Instagram, Facebook, TikTok, etc.
Core Feature Real‑time detection of encryption status, one‑click migration to secure channel.
Tech Stack JavaScript (extension), Swift/Java/Kotlin (mobile), Signal API integration.
Difficulty Medium
Monetization Hobby

Notes

  • Addresses the pain point: “Meta removing E2EE from Instagram DMs” and the fear of “AI training data.”
  • Users can keep their existing contacts while moving sensitive chats to a verified secure app.
  • Sparks conversation about the practicality of “switching” in a network‑effect world.

Privacy Score Dashboard

Summary

  • Aggregates privacy policies, data collection practices, and encryption status of popular apps into a single, user‑friendly score.
  • Provides actionable recommendations and alerts when an app changes its privacy stance.
  • Core value: empowers users to make informed choices amid opaque corporate practices.

Details

Key Value
Target Audience Privacy advocates, journalists, and everyday users.
Core Feature Automated policy parsing, real‑time score updates, comparison charts.
Tech Stack Python (scraping), NLP, PostgreSQL, React front‑end.
Difficulty High
Monetization Revenue‑ready: subscription for enterprises, API access for developers.

Notes

  • Resonates with comments about “data scoring” and “AI training data” concerns.
  • Provides a tangible metric for users to gauge the risk of using a platform.
  • Encourages transparency and could become a reference point for regulatory discussions.

Self‑Hosted XMPP Relay with OMEMO

Summary

  • A lightweight, easy‑to‑deploy XMPP server that supports OMEMO (Signal‑style) encryption and OpenPGP for XMPP.
  • Includes a mobile client that can be used as a drop‑in replacement for private conversations.
  • Core value: gives users full control over their messaging data, bypassing corporate backdoors.

Details

Key Value
Target Audience Privacy‑savvy individuals, small teams, self‑hosters.
Core Feature OMEMO/XMPP server, auto‑key rotation, optional end‑to‑end encrypted backups.
Tech Stack Prosody (XMPP), Docker, Go for client, TLS, WireGuard for VPN.
Difficulty Medium
Monetization Hobby

Notes

  • Directly addresses the need to “move sensitive conversations to something self‑hosted.”
  • Provides a practical alternative to “bypass the big platforms” while keeping the same chat experience.
  • Likely to spark discussion on self‑hosting feasibility and network effects.
