Project ideas from Hacker News discussions.

Running My Own XMPP Server

📝 Discussion Summary (Click to expand)

1. Client experience & feature parity
Users keep comparing how well each protocol works on desktop, mobile, and in terms of UI polish.
- “Most of my contacts made the switch, and I’m now at roughly 95 % Signal for day‑to‑day conversations.” – skerit
- “Element is terrible, and many contenders are better in a way or another, but all lack some essential feature to turn them into practical alternatives.” – ezst
- “Signal Desktop app is sluggish… occasionally clicking and dragging images onto the application will cause it to freeze and eventually crash.” – DaSHacka
- “FluffyChat works on Matrix and has funny stickers and emojis.” – simgt

2. Trust, security, and federation
The debate centers on who controls the data, how encryption is handled, and whether the network can scale without a single vendor.
- “Signal is openly opposed to federation and to letting alternative clients use their server.” – ezst
- “Telegram group chats have no E2EE, private messages aren't E2EE by default.” – zadikian
- “Signal is still one company running one service. If they shut down tomorrow or change direction, I’m back to square one.” – morning‑coffee
- “XMPP had rather bad name… unsuitability for mobile clients, absence of end‑to‑end encryption.” – zajio1am

3. Self‑hosting vs. network effects
People weigh the effort of running their own server against the reality that most contacts stay on big‑brand apps.
- “I’ve been running a matrix server for about 2 years for family. It’s… ok. Clients are bad.” – WD‑42
- “ejabberd is a bit overkill for a few people though. Prosody could be easily set up in 15 minutes or less.” – petre
- “Self‑hosting federated instances like this is pretty interesting way to scale.” – iamcalledrob
- “The only good solution would be if all messaging apps used the same protocol so everyone could be reached.” – elminjo

These three themes—client usability, security/federation concerns, and the tension between self‑hosting and the dominance of centralized services—drive the bulk of the discussion.


🚀 Project Ideas

Unified Lightweight Matrix & XMPP Desktop Client

Summary

  • A single, native desktop messenger that supports both Matrix and XMPP with a modern, accessible UI.
  • Solves pain points of heavy Electron apps, broken image sending, and lack of push notifications on desktop.
  • Core value: “One app, all your chats, no performance hit.”

Details

Key Value
Target Audience Desktop users who rely on Matrix or XMPP for family, friends, or small teams.
Core Feature Unified chat UI, native push notifications, stable media handling, accessibility (screen reader, high‑contrast).
Tech Stack Tauri + Rust for backend, React/TypeScript for UI, libsignal-protocol for E2EE, libxmpp for XMPP, libmatrix for Matrix.
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters complain about “Electron apps are wasteful” and “image sending breaks” (e.g., FluffyChat issue #2497).
  • A lightweight native client would appeal to users wanting “Signal‑like desktop experience” without the heavy footprint.
  • Discussion potential: comparing Tauri vs Electron, native push vs webhooks.

Self‑Hosted XMPP Bundle with Auto‑Setup Wizard

Summary

  • A Docker‑based XMPP server package that auto‑configures TLS, TURN, and invites, plus a companion mobile app.
  • Addresses the complexity of setting up Prosody/ejabberd and the need for easy onboarding.
  • Core value: “Run your own chat server in minutes, no sysadmin required.”

Details

Key Value
Target Audience Families, small teams, privacy‑conscious users wanting self‑hosted chat.
Core Feature One‑click Docker image, ACME TLS, auto‑TURN, invitation system, web UI for admin, pre‑built mobile client.
Tech Stack Docker, Docker‑Compose, Prosody (with mod_omemo), coturn, Caddy (for ACME), React Native mobile app.
Difficulty Medium
Monetization Revenue‑ready: $5/month for managed hosting, free self‑hosted.

Notes

  • Users like “Snikket” complain about “invite‑only” and “client compatibility.”
  • This bundle bundles the best parts of Snikket and Prosody, but with a simpler install path.
  • Practical utility: instant federation, E2EE via OMEMO, and push notifications via Caddy’s webhooks.

Cross‑Protocol E2EE Gateway Client

Summary

  • A single client that can talk to Matrix, XMPP (OMEMO), Signal, and Telegram via gateways, with unified key management.
  • Solves the “no single app for all chats” frustration and the need for E2EE across protocols.
  • Core value: “End‑to‑end encryption everywhere, one UI.”

Details

Key Value
Target Audience Power users who need secure messaging across multiple ecosystems.
Core Feature Unified contact list, automatic gateway selection, chain‑of‑trust key exchange, offline sync.
Tech Stack Electron (lightweight), libsignal-protocol, libxmpp, Matrix SDK, Telegram TDLib, Signal‑API wrapper.
Difficulty High
Monetization Revenue‑ready: $9.99/month for premium features (advanced encryption, backup).

Notes

  • HN users lament “no way to use Signal from XMPP” and “Telegram lacks E2EE.”
  • By bridging protocols, users can keep all contacts in one place while maintaining privacy.
  • Discussion: feasibility of secure key exchange across gateways, legal implications.

Email‑Based Chat with Push & E2EE

Summary

  • A web/mobile client that turns standard email into a real‑time chat, with optional PGP encryption and push notifications.
  • Addresses the “email + chat” idea that many HN users mention but lack a usable product for.
  • Core value: “Chat where everyone already has an inbox.”

Details

Key Value
Target Audience Users who prefer email but want instant messaging features.
Core Feature WebSocket‑based real‑time sync, PGP encryption, file attachments, push notifications via webhooks.
Tech Stack Node.js, Express, Socket.io, OpenPGP.js, React Native, Firebase Cloud Messaging for push.
Difficulty Medium
Monetization Hobby (open source) with optional paid PGP key‑management service.

Notes

  • Commenters note “DeltaChat moved away from email” and “latency is a dealbreaker.”
  • This project would keep the email‑backed nature but add real‑time sync and encryption.
  • Practical utility: users can chat without installing new apps, and existing email infrastructure can be leveraged.
