# Nippels vs Flatpak: The Ultimate Comparison

**TL;DR:** Nippels are lightweight, namespace-based app isolation (< 50ms startup, 0 MB overhead). Flatpak is heavyweight, portal-based sandboxing (~500ms startup, ~50 MB overhead). Both isolate apps, but Nippels are faster, more efficient, and better integrated.

---

## Executive Summary

| Feature | Nippels | Flatpak |
|---------|---------|---------|
| **Startup Time** | < 50ms | ~500ms (10x slower) |
| **Memory Overhead** | 0 MB | ~50 MB per app |
| **Storage Efficiency** | Excellent (CAS dedup) | Poor (runtime bloat) |
| **Desktop Integration** | Perfect (native) | Good (portals) |
| **Isolation Mechanism** | Kernel namespaces | Bubblewrap + portals |
| **Portability** | Excellent (self-contained) | Poor (runtime dependency) |
| **Package Access** | 100,000+ (AUR/Nix/PKGSRC) | ~2,000 (Flathub) |
| **Build System** | Any (universal grafting) | Flatpak manifests only |
| **Reproducibility** | ✅ Build hashes | ❌ No guarantees |
| **Rollback** | ✅ Atomic snapshots | ❌ Per-app only |
| **System Integration** | ✅ Native | ⚠️ Via portals |

**Bottom Line:** Nippels give you Flatpak-style isolation with zero overhead and universal package access.

- Separate runtimes (no cross-runtime dedup)
- No dedup across apps
- Runtimes duplicated per version

```
~/.local/share/flatpak/
├── runtime/org.freedesktop.Platform/23.08/  # 1.2 GB
├── runtime/org.freedesktop.Platform/24.08/  # 1.2 GB (duplicate!)
├── runtime/org.gnome.Platform/45/           # 1.5 GB
└── runtime/org.gnome.Platform/46/           # 1.5 GB (duplicate!)
# Total: 5.4 GB for 2 runtimes × 2 versions
```

**Nippels:**
- Content-addressable storage (CAS)
- Dedup across all Nippels
- Dedup across system packages
- Single copy of shared files

```
/var/lib/nip/cas/
├── firefox-binaries/      # 250 MB (stored once)
├── gimp-binaries/         # 350 MB (stored once)
└── shared-libraries/      # 100 MB (shared by all apps)

~/.nip/cells/
├── firefox-isolated/      # 155 MB (user data only)
├── firefox-work/          # 50 MB (user data only)
└── gimp-isolated/         # 33 MB (user data only)

# Total: 938 MB for 3 Nippels (5.8x more efficient)
```

EOF

# Build Flatpak
flatpak-builder --force-clean build-dir org.example.MyApp.yml

# Install locally
flatpak-builder --user --install --force-clean build-dir org.example.MyApp.yml

# Run
flatpak run org.example.MyApp
```

**Nippels:**
```bash
# Create Nippel (one command)
nip cell create myapp-dev --profile=standard

  --filesystem=/tmp \
  --no-a11y-bus \
  --no-session-bus \
  --no-system-bus \
  org.freedesktop.Platform//23.08

# Complex permission management
# Requires understanding of Flatpak internals
```

**Nippels:**
