+# StackCP Hosting Evaluation Report
+
+**Date**: 2025-10-19
+**Server**: ssh-node-gb.lhr.stackcp.net
+**User**: digital-lab.ca
+**Provider**: 20i (StackCP Shared Hosting)
+
+---
+
+## Executive Summary
+
+✅ **NaviDocs CAN run on this StackCP hosting!**
+
+The key insight: **StackCP allows executables in `/tmp` directory** despite having `noexec` on home directories. This is the "shared hosting with executable directory" you mentioned.
+
+---
+
+## System Information
+
+```
+OS: Linux 5.14.0-570.52.1.el9_6.x86_64
+Architecture: x86_64
+Home Directory: /home/sites/7a/c/cb8112d0d1/
+Sudo Access: NO
+```
+
+---
+
+## What's Available
+
+### ✅ Working Out of the Box:
+
+| Component | Version | Status |
+|-----------|---------|--------|
+| **Node.js** | v20.19.5 | ✅ Running from `/tmp/node` |
+| **npm** | Latest | ✅ Available |
+| **Python3** | 3.9.21 | ✅ Available |
+| **MySQL/MariaDB** | 10.6.23 | ✅ Available |
+| **Git** | 2.47.3 | ✅ Available |
+| **ImageMagick** | 7.1.1-43 | ✅ Available |
+| **Meilisearch** | Running | ✅ Already running on port 7700! |
+
+### ❌ Not Available (But We Can Fix):
+
+| Component | Status | Solution |
+|-----------|--------|----------|
+| **SQLite3** | Missing | Use `better-sqlite3` npm package |
+| **Redis** | Missing | Use Redis Cloud (free tier) |
+| **Tesseract** | Missing | Use Google Cloud Vision API |
+| **PM2/Screen** | Missing | Use StackCP's Node.js manager |
+
+---
+
+## The Key Discovery: `/tmp` is Executable!
+
+### How StackCP Works:
+
+1. **Home directory** (`/home/sites/...`) has `noexec` (security)
+2. **`/tmp` directory** has execute permissions ✅
+3. **Workaround**: Run binaries from `/tmp`, symlink from `~/bin`
+
+### Current Setup (Already Working):
+```
+~/bin/node → /tmp/node (97MB, Node.js v20.19.5)
+/tmp/meilisearch (120MB, running on port 7700)
+```
+
+### Directory Structure:
+```
+/home/sites/7a/c/cb8112d0d1/
+├── public_html/          # Web root

+```
+
+---
+
+## NaviDocs Deployment Strategy for StackCP
+
+### Option 1: Full Stack (Recommended)
+
+```bash
+# 1. Use better-sqlite3 (npm package, no binary needed)
+npm install better-sqlite3
+
+# 2. Use Redis Cloud (free tier: 30MB)
+# Sign up at: https://redis.com/try-free/
+REDIS_HOST=your-instance.redis.cloud
+REDIS_PORT=xxxxx
+REDIS_PASSWORD=your-password
+
+# 3. Use Google Cloud Vision API for OCR
+# - No Tesseract binary needed
+# - 1,000 pages/month FREE
+# - Handwriting support
+PREFERRED_OCR_ENGINE=google-vision
+
+# 4. Meilisearch is already running!
+# Just configure to use existing instance
+MEILISEARCH_HOST=http://127.0.0.1:7700
+```
+
+### Option 2: Minimal (All Cloud)
+
+```bash
+# Use cloud services for everything except Node.js:
+# - Redis Cloud (free tier)
+# - Google Cloud Vision (free tier: 1000/month)
+# - Meilisearch Cloud (free tier: 100K docs)
+
+# Advantages:
+# - No binary compatibility issues
+# - Better performance
+# - Auto-scaling
+# - Managed backups
+```
+
+---
+
+## Step-by-Step Deployment Guide
+
+### 1. Setup Environment Helpers
+
+```bash
+# SSH into StackCP
+ssh stackcp
+
+# Setup helper script (already uploaded during evaluation)
+source ~/stackcp-setup.sh
+
+# This provides convenient aliases:
+# - node  → /tmp/node
+# - npm   → /tmp/npm (helper script)
+# - navidocs-start, navidocs-stop, navidocs-status (management functions)
+```
+
+### 2. Install Dependencies
+
+```bash
+# Create directories
+mkdir -p ~/navidocs/{uploads,db,logs}
+mkdir -p /tmp/navidocs
+
+# Clone repository to /tmp (executable directory!)
+cd /tmp/navidocs
+git clone <your-repo-url> .
+
+# Install dependencies
+cd server
+/tmp/npm install --production --no-audit --no-fund
+
+cd ../client
+/tmp/npm install --no-audit --no-fund
+```
+
+**Important**: Code MUST be in `/tmp/navidocs` because:
+- Native modules (better-sqlite3) need compilation
+- Home directory has `noexec` flag
+- `/tmp` allows executables
+
+### 3. Configure Environment
+
+```bash
+# server/.env
+NODE_ENV=production
+PORT=3001
+
+# Database - using better-sqlite3
+DATABASE_PATH=/home/sites/7a/c/cb8112d0d1/navidocs/server/db/navidocs.db
+
+# Redis Cloud (free tier)
+REDIS_HOST=redis-12345.redis.cloud
+REDIS_PORT=12345
+REDIS_PASSWORD=your-password
+
+# Meilisearch (already running locally!)
+MEILISEARCH_HOST=http://127.0.0.1:7700
+MEILISEARCH_MASTER_KEY=<check-running-instance>
+MEILISEARCH_INDEX_NAME=navidocs-pages
+
+# OCR - Google Cloud Vision API
+PREFERRED_OCR_ENGINE=google-vision
+GOOGLE_APPLICATION_CREDENTIALS=/home/sites/7a/c/cb8112d0d1/navidocs/server/config/google-credentials.json
+
+# File Upload
+MAX_FILE_SIZE=50000000
+UPLOAD_DIR=/home/sites/7a/c/cb8112d0d1/navidocs/uploads
+
+# JWT
+JWT_SECRET=your-secure-random-string
+JWT_EXPIRES_IN=7d
+```
+
+### 4. Update Database Code for better-sqlite3
+
+The current code uses `Database` from `better-sqlite3`, so it should work!
+
+Just verify in `server/config/db.js`:
+```javascript
+import Database from 'better-sqlite3';  // ✅ Already using this!
+```
+
+### 5. Initialize Database
+
+```bash
+cd /tmp/navidocs/server
+/tmp/node db/init.js
+```
+
+### 6. Start Services
+
+#### Option A: Using Helper Function (Easiest)
+```bash
+source ~/stackcp-setup.sh
+navidocs-start
+navidocs-status
+```
+
+#### Option B: Using StackCP Node.js Manager (Recommended for Production)
+```
+1. Log into StackCP control panel
+2. Go to "Advanced" → "Node.js Applications"
+3. Add Application:
+   - Path: /tmp/navidocs/server (IMPORTANT: /tmp, not ~/!)
+   - Startup file: index.js
+   - Node version: 20.x
+   - Port: 3001
+4. Start application
+5. Configure reverse proxy: yoursite.com → http://127.0.0.1:3001
+```
+
+#### Option C: Manual (Using nohup)
+```bash
+# Start API server
+cd /tmp/navidocs/server
+nohup /tmp/node index.js > ~/navidocs/logs/server.log 2>&1 &
+
+# Start OCR worker
+nohup /tmp/node workers/ocr-worker.js > ~/navidocs/logs/worker.log 2>&1 &
+```
+
+### 7. Build Frontend
+
+```bash
+cd /tmp/navidocs/client
+/tmp/npm run build
+
+# Serve via Apache/Nginx (StackCP manages this)
+cp -r dist/* ~/public_html/
+```
+
+---
+
+## Redis Cloud Setup (Free Tier)
+
+```bash
+# 1. Sign up: https://redis.com/try-free/
+# 2. Create database (free tier: 30MB)
+# 3. Get connection details
+# 4. Update .env:
+
+REDIS_HOST=redis-12345.c1.us-east-1-2.ec2.redis.cloud
+REDIS_PORT=12345
+REDIS_PASSWORD=your-password
+```
+
+**Why Redis Cloud:**
+- ✅ 30MB free tier (enough for thousands of jobs)
+- ✅ No binary installation needed
+- ✅ Managed, always available
+- ✅ Better than shared hosting Redis
+
+---
+
+## Google Cloud Vision API Setup
+
+```bash
+# 1. Create Google Cloud project
+# 2. Enable Cloud Vision API
+# 3. Create service account
+# 4. Download JSON credentials
+# 5. Upload to server:
+
+scp google-credentials.json stackcp:~/navidocs/server/config/
+
+# 6. Update .env
+PREFERRED_OCR_ENGINE=google-vision
+GOOGLE_APPLICATION_CREDENTIALS=/home/sites/7a/c/cb8112d0d1/navidocs/server/config/google-credentials.json
+```
+
+---
+
+## Resource Limits
+
+```
+File size limit: 52428800 blocks (~50GB)
+Open files: 1024
+Max processes: 31349
+Disk space: 8.7TB (96% used - 361GB available)
+Memory: 7.8GB total
+```
+
+**Recommendation**: Monitor disk usage, but plenty of resources for NaviDocs.
+
+---
+
+## What's Already Running
+
+```bash
+# Meilisearch is ALREADY running!
+# Process: /tmp/meilisearch
+# Port: 7700
+# Data: ~/.meilisearch_data/
+
+# To use it:
+# 1. Find the master key (check startup logs or config)
+# 2. Update .env with MEILISEARCH_MASTER_KEY
+# 3. Test: curl http://127.0.0.1:7700/health
+```
+
+---
+
+## Challenges & Solutions
+
+### Challenge 1: No Executable Permissions in Home
+✅ **Solution**: Use `/tmp` for binaries, symlink from `~/bin`
+
+### Challenge 2: No SQLite3 Binary
+✅ **Solution**: Use `better-sqlite3` npm package (already in use!)
+
+### Challenge 3: No Redis
+✅ **Solution**: Redis Cloud free tier (30MB)
+
+### Challenge 4: No Tesseract
+✅ **Solution**: Google Cloud Vision API (1000 pages/month free)
+
+### Challenge 5: No PM2/Screen
+✅ **Solution**: StackCP's Node.js Application Manager
+
+### Challenge 6: Process Persistence
+✅ **Solution**: StackCP auto-restarts Node.js apps
+
+---
+
+## Performance Considerations
+
+### Pros:
+- ✅ Meilisearch already running
+- ✅ Node.js v20 (latest LTS)
+- ✅ Good memory (7.8GB)
+- ✅ SSD storage (fast)
+
+### Cons:
+- ⚠️  Shared environment (CPU limits)
+- ⚠️  Network latency for cloud services
+- ⚠️  No background job management (use StackCP manager)
+
+---
+
+## Cost Analysis
+
+### Current StackCP Hosting:
+- **Cost**: $X/month (whatever you're paying)
+- **Includes**: Everything except Redis and OCR
+
+### Additional Free Services:
+- **Redis Cloud**: $0 (30MB free tier)
+- **Google Vision API**: $0 (1,000 pages/month free)
+- **Meilisearch**: $0 (already running locally)
+
+### Estimated Monthly Costs:
+```
+StackCP Hosting:     $X (existing)
+Redis Cloud:         $0 (free tier)
+Google Vision:       $0-$6 (depends on volume)
+------------------------
+Total:               $X + $0-$6/month
+```
+
+### Compared to VPS Alternative:
+```
+DigitalOcean VPS:    $6/month
+Setup complexity:    Higher
+Control:             Full
+```
+
+**Verdict**: StackCP is cost-effective if you're already paying for it!
+

+
+## Deployment Verification Tests (Completed!)
+
+### ✅ Phase 1: Core Infrastructure Testing
+
+**Tested on 2025-10-19 08:30 UTC**
+
+| Test | Status | Details |
+|------|--------|---------|
+| Node.js execution from `/tmp` | ✅ PASS | v20.19.5 runs perfectly |
+| npm package installation | ✅ PASS | Installed 38 packages in `/tmp` |
+| better-sqlite3 native module | ✅ PASS | Compiled and works in `/tmp` |
+| Express server | ✅ PASS | Listening on port 3333 |
+| SQLite database operations | ✅ PASS | CREATE, INSERT, SELECT all work |
+| Meilisearch connectivity | ✅ PASS | Health endpoint returns "available" |
+
+### Test Results:
+
+```bash
+# Node.js execution test
+/tmp/node --version
+# ✅ v20.19.5
+
+# npm test
+/tmp/node .../npm-cli.js install better-sqlite3
+# ✅ added 38 packages in 2s
+
+# better-sqlite3 test
+const db = new Database(':memory:');
+db.exec('CREATE TABLE test (id INTEGER PRIMARY KEY, name TEXT)');
+db.prepare('INSERT INTO test (name) VALUES (?)').run('StackCP Test');
+# ✅ Works perfectly!
+
+# Express + Meilisearch test server
+GET http://127.0.0.1:3333/
+# ✅ {"status":"ok","sqlite":[{"id":1,"name":"StackCP Test"}],"node":"v20.19.5","platform":"linux"}
+
+GET http://127.0.0.1:3333/health
+# ✅ {"meilisearch":{"status":"available"}}
+```
+
+### Key Findings:
+
+1. **npm MUST be executed via `/tmp/node`** because home directory has `noexec`:
+   ```bash
+   # ❌ This fails:
+   ~/bin/npm install package
+
+   # ✅ This works:
+   /tmp/node ~/local/nodejs/lib/node_modules/npm/bin/npm-cli.js install package
+   ```
+
+2. **Native npm modules MUST be installed in `/tmp`**:
+   - Home directory: `noexec` prevents compilation
+   - `/tmp` directory: Full executable permissions ✅
+
+3. **Recommended deployment structure**:
+   ```
+   /tmp/navidocs/               # Application code + node_modules
+   ~/navidocs/                  # Data directory (noexec is fine)
+   ├── uploads/                 # File storage
+   ├── db/                      # SQLite database
+   ├── logs/                    # Application logs
+   └── .env                     # Configuration
+   ```
+
+### ✅ Phase 2: Full NaviDocs Deployment (Ready!)
+
+All prerequisites verified. Ready to deploy full application:
+
+- [x] Upload binary to `/tmp` ✅ (Node.js already there)
+- [x] Test executable runs ✅ (v20.19.5 confirmed)
+- [x] Install better-sqlite3 ✅ (Tested and working)

+# Deploying NaviDocs on StackCP (20i Hosting)
+
+## What is StackCP?
+
+**StackCP** is a proprietary hosting control panel developed by **20i** (a UK-based hosting provider).
+
+### Key Facts:
+- **Developer**: 20i (https://www.20i.com)
+- **Type**: Custom-built control panel (alternative to cPanel/Plesk)
+- **Target**: Reseller hosting and shared hosting customers
+- **Features**: Email management, File Manager, FTP, databases, malware scanning, 80+ one-click installs
+
+## Important: Node.js Support on StackCP
+
+### ❌ Standard Shared Hosting (StackCP)
+**Node.js is NOT supported on 20i's shared hosting platform.**
+
+From 20i documentation:
+> "Node.JS isn't currently supported on the shared hosting platform. If NodeJS is a requirement, you should consider purchasing Managed Hosting."
+
+### ✅ Managed VPS/Cloud Hosting (with StackCP)
+**Node.js IS supported on 20i's Managed VPS and Cloud Server offerings.**
+
+These include:
+- Node.js application registration tool
+- Custom executable directory permissions
+- Full control over server environment
+
+## Understanding "Executable Directory" on StackCP
+
+When you mentioned **"shared hosting but with an executable directory"**, this likely refers to:
+
+### Option 1: Managed Cloud Hosting (Most Likely)
+20i's **Managed Cloud Hosting** allows:
+- ✅ Running Node.js applications
+- ✅ Custom executable binaries (like Meilisearch, Tesseract)
+- ✅ SSH access
+- ✅ Custom directory permissions
+- ✅ Long-running processes (workers)
+
+**This is what you need for NaviDocs!**
+
+### Option 2: Shared Hosting with Limited Binaries (Not Suitable)
+Some shared hosts allow static binaries in specific directories, but:
+- ❌ No Node.js runtime
+- ❌ No long-running processes
+- ❌ No background workers
+- ❌ Limited to PHP/Python CGI scripts
+
+**NaviDocs requires Node.js - shared hosting won't work.**
+
+## StackCP Tech Stack (Based on 20i Infrastructure)
+
+### Server Environment:
+```
+Operating System: Linux (likely CentOS/AlmaLinux)
+Web Server: Apache/Nginx (varies by plan)
+Control Panel: StackCP (proprietary)
+Database: MySQL/MariaDB (managed)
+File Manager: Built-in StackCP File Manager
+FTP/SFTP: Supported
+SSH: Available on VPS/Cloud plans
+```
+
+### For Managed Hosting (Node.js):
+```
+Node.js: Multiple versions available (select via StackCP)
+Package Manager: npm/yarn
+Process Manager: PM2 or custom (you manage)
+Reverse Proxy: Configured via StackCP
+SSL/TLS: Let's Encrypt (free, auto-renew)
+```
+
+### Directory Structure (Typical):
+```
+/home/username/
+├── public_html/          # Web root (static files)
+├── node_apps/            # Node.js applications
+│   └── navidocs/

+cd ~/node_apps/navidocs
+node server/workers/ocr-worker.js
+# Press Ctrl+A then D to detach
+```
+
+##### Main Application (via StackCP):
+```
+1. Go to StackCP → Node.js Applications
+2. Find your NaviDocs app
+3. Click "Start"
+4. StackCP will manage the process automatically
+```
+
+#### 7. Configure Reverse Proxy in StackCP
+```
+1. StackCP → Domains → yoursite.com
+2. Add reverse proxy:
+   - Source: yoursite.com
+   - Target: http://127.0.0.1:3001
+   - Enable SSL (Let's Encrypt)
+3. Save
+```
+
+#### 8. Build and Serve Frontend
+```bash
+# Option A: Serve via Node.js (included in backend)
+# Already done - the backend serves the built frontend
+
+# Option B: Serve via Apache/Nginx (StackCP manages)
+cd ~/node_apps/navidocs/client
+npm run build
+
+# Copy build to web root
+cp -r dist/* ~/public_html/
+
+# Configure StackCP to proxy API calls to Node.js:
+# yoursite.com/api/* → http://127.0.0.1:3001/api/*
+```
+
+## Recommended Approach for StackCP
+
+### Use Google Cloud Vision API for OCR
+Since StackCP shared/managed hosting may have limited system package installation:
+
+```env
+# Avoid Tesseract dependency issues
+PREFERRED_OCR_ENGINE=google-vision
+
+# Or use Drive API (slower but free)
+PREFERRED_OCR_ENGINE=google-drive
+```
+
+This eliminates the need for:
+- Tesseract binaries
+- Poppler utils
+- Language training data
+
+### Use Managed Redis
+Check if 20i offers managed Redis, or use Redis Cloud (free tier):
+```env
+REDIS_HOST=your-redis-instance.redis.cloud
+REDIS_PORT=12345
+REDIS_PASSWORD=your-password
+```
+
+### Monitor with PM2
+```bash
+# Install PM2
+npm install -g pm2
+
+# Start worker with PM2
+pm2 start server/workers/ocr-worker.js --name navidocs-worker
+
+# Save PM2 configuration
+pm2 save
+
+# Setup PM2 startup (if you have sudo)
+pm2 startup
+```
+
+## StackCP Limitations for NaviDocs
+
+### ⚠️ Challenges:
+1. **Limited system package installation** (no apt-get on shared)
+2. **No background service management** (no systemd on shared)
+3. **Resource limits** (CPU, RAM, concurrent connections)
+4. **File system permissions** (may restrict executable binaries)
+
+### ✅ Solutions:
+1. **Use Google Cloud APIs** instead of local binaries
+2. **Use PM2 or screen** for background processes
+3. **Upgrade to VPS** if limits are hit
+4. **Contact 20i support** for executable permissions
+
+## Alternative: Deploy on VPS Instead
+
+If StackCP's managed hosting is too restrictive, consider:
+
+### 20i Managed VPS (Full Control):
+```
+✅ Full sudo access
+✅ Install any packages
+✅ Systemd services
+✅ More resources
+✅ Better for NaviDocs
+```
+
+### Other VPS Providers:
+- **DigitalOcean** ($6/month droplet)
+- **Linode** ($5/month)
+- **Vultr** ($6/month)
+- **AWS Lightsail** ($3.50/month)
+
+All offer:
+- Full Linux environment
+- Node.js support
+- Background workers
+- Custom executables
+
+## Getting Help
+
+### 20i Support:
+- **Email**: support@20i.com
+- **Docs**: https://docs.20i.com
+- **Ask about**:
+  - Node.js version availability
+  - Executable binary permissions
+  - Background process management
+  - Redis/Meilisearch installation
+
+### StackCP-Specific Questions:
+1. Can I run custom binaries in `~/bin`?
+2. Is Redis available or can I use Redis Cloud?
+3. Can I keep background workers running (OCR worker)?
+4. What's the best way to manage Node.js processes?
+
+## Summary
+
+**StackCP** is 20i's control panel, but for **NaviDocs you need**:
+
+| Feature | Shared Hosting | Managed VPS | ✅ Needed for NaviDocs |
+|---------|---------------|-------------|----------------------|
+| Node.js | ❌ | ✅ | ✅ |
+| Custom binaries | ❌ | ✅ | ⚠️ Optional (use Google APIs) |
+| Background workers | ❌ | ✅ | ✅ |
+| Redis | ❌ | ✅ | ✅ |
+| SSH access | ❌ | ✅ | ✅ |
+
+**Recommendation**:
+- If you have **Managed VPS/Cloud** with StackCP: Follow this guide ✅
+- If you have **Shared Hosting** with StackCP: Upgrade to VPS or switch providers ❌
+
+The "executable directory" likely means you have VPS access - verify with 20i support!

+    "password": "Test123!",
+    "name": "Test User"
+  }'
+
+# Login
+TOKEN=$(curl -X POST http://127.0.0.1:3001/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@navidocs.com",
+    "password": "Test123!"
+  }' | jq -r '.token')
+
+# Upload PDF

+  -F "title=Test Manual" \
+  -F "category=manuals"
+```
+
+## 5. Access Application
+
+### Frontend
+```
+https://yoursite.com
+```
+
+### API
+```
+https://yoursite.com/api/health
+```
+
+## Management Commands
+
+```bash
+# Source helpers first
+source ~/stackcp-setup.sh
+
+# Start services
+navidocs-start
+
+# Stop services
+navidocs-stop
+
+# Check status
+navidocs-status
+
+# View logs
+tail -f ~/navidocs/logs/server.log
+tail -f ~/navidocs/logs/worker.log
+
+# Restart after code changes
+navidocs-stop
+cd /tmp/navidocs
+git pull
+cd server && /tmp/npm install
+cd ../client && /tmp/npm run build && cp -r dist/* ~/public_html/
+navidocs-start
+```
+
+## Troubleshooting
+
+### npm Permission Denied
+```bash
+# ❌ Don't do this:
+~/bin/npm install
+
+# ✅ Do this instead:
+/tmp/npm install
+```
+
+### Native Module Build Fails
+```bash
+# Ensure you're in /tmp, not home directory:
+cd /tmp/navidocs/server
+/tmp/npm install better-sqlite3
+```
+
+### Services Won't Start
+```bash
+# Check logs
+tail -100 ~/navidocs/logs/server.log
+
+# Check ports
+netstat -tln | grep -E "3001|7700|6379"
+
+# Kill stuck processes
+pkill -f "node index.js"
+pkill -f "node workers/ocr-worker.js"
+```
+
+### Meilisearch Auth Error
+```bash
+# Find the master key from running process
+ps aux | grep meilisearch
+
+# Or restart Meilisearch with known key
+pkill meilisearch
+cd /tmp
+./meilisearch --master-key="your-key-here" \
+  --db-path=~/.meilisearch_data \
+  --http-addr=127.0.0.1:7700 \
+  --env=production > ~/navidocs/logs/meilisearch.log 2>&1 &
+```
+
+## Performance Tips
+
+### 1. Use Cloud Services
+- Redis Cloud (free 30MB) instead of local
+- Google Vision (free 1K pages/month) instead of Tesseract
+- Meilisearch Cloud if local instance is slow
+
+### 2. Monitor Resource Usage
+```bash
+# Check disk space
+df -h ~
+
+# Check memory
+free -h
+
+# Check processes
+ps aux | grep $(whoami)
+```
+
+### 3. Optimize Database
+```bash
+# Regular SQLite maintenance
+cd /tmp/navidocs/server
+/tmp/node -e "const db = require('better-sqlite3')('~/navidocs/db/navidocs.db'); db.pragma('optimize'); db.close();"
+```
+
+## Cost Summary
+
+| Service | Cost | What You Get |
+|---------|------|--------------|
+| StackCP Hosting | $X/month | Everything (already paying) |
+| Redis Cloud | $0 | 30MB free tier |
+| Google Vision API | $0 | 1,000 pages/month free |
+| **Total** | **$X/month** | Full NaviDocs deployment |
+
+After free tier:
+- Redis: $0.20/GB/month ($6/month for 30GB)
+- Vision API: $1.50 per 1,000 pages
+
+## Support
+
+- **StackCP**: support@20i.com
+- **NaviDocs**: Check GitHub issues
+- **This Guide**: /home/setup/navidocs/docs/STACKCP_QUICKSTART.md

+2. **Setup Monitoring**: Use StackCP's built-in monitoring
+3. **Configure Domain**: Point your domain to StackCP
+4. **SSL Certificate**: Enable Let's Encrypt in StackCP
+5. **Test OCR**: Upload handwritten documents to verify Google Vision
+
+---
+
+**Deployment Time**: ~30 minutes total
+**Difficulty**: 3/10 (straightforward with this guide)
+**Performance**: Good for small-medium workloads
