Known Limitations - v0.9.1-beta

Status: Beta Release Completion: ~80% Feature Complete Last Updated: February 5, 2026

Executive Summary

nself-chat v0.9.1 is a solid beta release with a strong foundation and core features working well. However, several features are in MVP state, have mocked implementations, or require additional testing. This document provides an honest assessment of what works, what's limited, and what needs improvement.

TL;DR: Great for development and testing. Core messaging, real-time features, and UI are production-ready. Some advanced features (payments client, video processing) are MVP or mocked.

Implementation Status Overview

✅ Production Ready (60-70% of features)

These features are fully implemented, tested, and ready for production use:

Build & Deploy

  • Zero TypeScript errors ✅
  • Build works successfully ✅
  • Docker/Kubernetes configs
  • Multi-platform scaffolding

⚠️ MVP / Partial Implementation (20-25% of features)

These features exist but have limitations, mocked components, or partial implementations:

1. Payments (Stripe Integration)

Status: Server-side real, client-side mocked

What Works:

  • ✅ Server-side Stripe integration (real API)
  • ✅ Webhook handling
  • ✅ Subscription plans configured
  • ✅ Customer management

What's Limited:

  • ⚠️ Client-side uses mock payment intents
  • ⚠️ Payment UI shows but doesn't process real cards
  • ⚠️ No actual Stripe.js integration on frontend

Impact: Payment flows appear to work but don't charge real cards

Code Reference:

// src/lib/payments/stripe-client.ts:257
// Generate mock payment intent
const paymentIntent: PaymentIntent = {
  id: `pi_${this.generateId()}`,
  clientSecret: `pi_${this.generateId()}_secret_${this.generateId()}`,
  // ... mock data
}

To Fix: 8-12 hours

  • Integrate real Stripe.js
  • Add payment element
  • Test with Stripe test cards
  • Handle 3D Secure flows

2. Media Processing (Video)

Status: Images fully supported, videos not implemented

What Works:

  • ✅ Image uploads (drag-drop, paste)
  • ✅ Image optimization (Sharp.js)
  • ✅ Image previews and gallery
  • ✅ AVIF/WebP conversion
  • ✅ Audio uploads

What's Limited:

  • ❌ Video processing not implemented
  • ⚠️ Video uploads accepted but not transcoded
  • ⚠️ No video thumbnails
  • ⚠️ No video compression

Impact: Video files can be uploaded but won't play optimally

Code Reference:

// Video processing throws "not implemented in MVP"
// Would need FFmpeg integration

To Fix: 16-24 hours

  • Integrate FFmpeg.js or cloud service
  • Add video transcoding pipeline
  • Generate video thumbnails
  • Implement HLS streaming for large videos

3. End-to-End Encryption

Status: Complete implementation, different from documentation claims

What Works:

  • ✅ Full Double Ratchet algorithm implemented
  • ✅ Perfect forward secrecy
  • ✅ Break-in recovery
  • ✅ Key management
  • ✅ Session handling

What's Different:

  • ⚠️ Uses Web Crypto API (not Signal Protocol library)
  • ⚠️ Custom implementation based on Signal spec
  • ⚠️ Not using @signalapp/libsignal-client in production

Impact: None - works correctly, just different approach

Code Reference:

// src/lib/encryption/ratchet.ts
// Complete Double Ratchet implementation using Web Crypto API
// Based on Signal Protocol specification

Note: This is a valid implementation choice. The documentation incorrectly claimed we use the Signal Protocol library, but we actually implemented the algorithm ourselves using Web Crypto API. Both approaches are secure.

To Clarify: Update docs to reflect "Double Ratchet algorithm (Web Crypto API)" instead of "Signal Protocol library"

4. WebRTC Voice/Video Calling

Status: Fully implemented, needs device testing

What Works:

  • ✅ 1-on-1 calls
  • ✅ Group calls (up to 50 participants)
  • ✅ Screen sharing
  • ✅ Virtual backgrounds
  • ✅ Call recording
  • ✅ LiveKit integration
  • ✅ 10,000+ lines of code

What's Limited:

  • ⚠️ Not tested on real mobile devices
  • ⚠️ CallKit integration untested
  • ⚠️ Telecom Manager (Android) untested
  • ⚠️ Network edge cases may exist

Impact: May have device-specific bugs

To Fix: 8-12 hours

Impact: Unknown device-specific issues

To Fix: 12-16 hours

  • Install on test devices (iPhone, Android)
  • Test all major features
  • Fix device-specific bugs
  • Prepare App Store/Play Store assets

6. Desktop Apps (Electron/Tauri)

Status: Configured and buildable, icons missing

What Works:

  • ✅ Electron configuration
  • ✅ Tauri configuration
  • ✅ Window management
  • ✅ System tray
  • ✅ Auto-updates configured

What's Limited:

  • ⚠️ No app icons (uses default)
  • ⚠️ No DMG/installer branding

Impact: Apps work but look unpolished

To Fix: 4-6 hours

  • Design and generate icons (1024x1024)
  • Create DMG background
  • Add installer branding
  • Configure code signing certificates

7. OAuth Providers

Status: Framework complete, individual providers need testing

What Works:

  • ✅ 11 providers configured
  • ✅ OAuth flow implemented
  • ✅ Account linking
  • ✅ Error handling

What's Limited:

  • ⚠️ Not all providers tested end-to-end
  • ⚠️ Some provider credentials may be test/sandbox
  • ⚠️ Rate limiting needs verification

Impact: May have provider-specific issues

To Fix: 8-12 hours

  • Test each provider thoroughly
  • Verify production credentials
  • Test edge cases (denied permissions, etc.)

❌ Not Implemented (5-10% of features)

These features are mentioned in documentation but not implemented:

  1. Advanced Analytics Dashboard: Metrics collection exists, but no admin dashboard UI
  2. Bot Marketplace: Bot SDK exists, but no public marketplace
  3. Advanced Moderation AI: Basic profanity filter exists, but no ML-based toxicity detection
  4. Social Media Embeds: Link previews work, but no rich Instagram/TikTok/Twitter embeds
  5. Workflow Automation: Webhooks exist, but no Zapier-style workflow builder

Impact: Features are missing but not critical for core functionality

To Implement: Each would take 16-40 hours
