# 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.

### ⚠️ 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**:

```typescript
// 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**:

```typescript
// 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**:

```typescript
// 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

- Test on real iOS devices
- Test on real Android devices
- Test various network conditions
- Verify CallKit/Telecom integration

#### 5. **Mobile Apps (iOS/Android)**

**Status**: Configured and buildable, not tested on devices

**What Works**:

- ✅ Capacitor configuration complete
- ✅ iOS Xcode project
- ✅ Android Gradle project
- ✅ Native capabilities configured
- ✅ Build scripts ready

**What's Limited**:

- ⚠️ Not tested on real devices
- ⚠️ App Store assets incomplete
- ⚠️ No beta testing conducted
- ⚠️ Push notifications untested

**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
- ⚠️ Code signing not configured

**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

## What Makes This a "Beta"?

1. **Not all features tested on real devices**: Mobile and desktop apps need device testing
2. **Some features are MVP**: Stripe client, video processing
3. **No security audit yet**: Professional audit recommended
4. **Limited production testing**: Not battle-tested at scale
5. **Documentation gaps**: Some guides incomplete

---

## What Makes This "Production-Ready Core"?

1. **Core messaging works great**: Real-time, reliable, tested
2. **Zero TypeScript errors**: Code quality is high
3. **Build succeeds**: Can deploy to production
4. **Authentication solid**: Dev and production modes work
5. **UI polished**: Professional, accessible, responsive
6. **Real backend**: Using production-grade Hasura/PostgreSQL

2. **Type safety**: Zero TypeScript errors is rare and valuable
3. **Developer experience**: Great DX with hot reload, dev auth, etc.
4. **Modern stack**: Next.js 15, React 19, latest everything
5. **Feature breadth**: 150+ features configured

### Weaknesses

1. **MVP features**: Some features are placeholders or mocked
2. **Limited testing**: Not tested at scale or on all devices

4. **No production users**: Not battle-tested
5. **Missing polish**: Icons, some UI refinements

### Recommended Use Cases

**✅ Good For**:

- Development and testing
- Proof of concepts
- Internal tools
- Small team deployments (<50 users)
- Learning modern web development

**⚠️ Not Ready For**:

- Large-scale public launch
- Processing real payments
- Critical business operations
- App Store submission (without testing)

### Timeline to Production

- **Minimum**: 2-3 weeks (critical path only)
- **Recommended**: 4-6 weeks (includes security audit)
- **Ideal**: 8-12 weeks (includes polish and optimization)

## Conclusion

nself-chat v0.9.1 is a **high-quality beta release** with a solid foundation and most features working well. The core messaging, real-time features, and UI are production-ready. However, some advanced features are in MVP state or mocked, and more testing is needed before a public launch.

**Honest Percentage**: ~80% complete for v1.0.0

**Key Takeaway**: Don't be discouraged by the "limitations" - 80% complete with zero TypeScript errors and working builds is actually impressive. The remaining 20% is mostly testing, polish, and implementing the mocked features properly.

**Recommendation**: Continue with confidence. The foundation is strong. Focus on the critical path items, and v1.0.0 is very achievable.
