  • Idle usage: 400MB
  • Active with extensions: 1.5GB+
  • Version 2.1.x had memory leak issues (2GB+ idle)
• Startup time: 4 seconds
• Background process: Continues running when window closed

Installation Process

• Basic install: 2 minutes (download from claude.ai/download)
• Extension setup: 10-30 minutes (improved from 2+ hours in 2024)
• Enterprise deployment: Supports Group Policy (Windows) and MDM (macOS)

Extension Ecosystem (Desktop Extensions - 2025 Overhaul)

Installation Method

• Format: .dxt files (drag-and-drop installation)
• Dependency management: Automatic
• API key storage: System keychain (secure)
• Cross-platform sync: Automatic configuration sync
• Directory size: 100+ extensions available
• Working rate: 80% don't crash on startup

Critical Extensions

Extension	Reliability	Failure Modes
File system access	High	Works well for text files
GitHub integration	Medium	Times out on repos >100 files with "TIMEOUT_EXCEEDED"
Screen capture	High	Kernel panic on 4K monitors (2 reported incidents)
Calendar access	Low	Event corruption, duplication issues
Socket MCP	Medium	Security scanning for dependencies
Discord integration	Medium	Bot management functionality

File Creation Feature (September 9, 2025)

Capabilities

• Output formats: Excel, PowerPoint, PDF, Word documents
• Backend: Server-side Ubuntu container with Python/Node.js
• Use case: Data analysis to formatted reports with charts/formulas

Access Requirements

• Subscription tiers: Max/Team/Enterprise only (Pro "coming weeks")
• Manual activation: Settings > Features > Experimental > "Upgraded file creation and analysis"

Security Warnings

• Internet access: Limited container internet access creates prompt injection risks
• Monitoring requirement: "Monitor chats closely" for malicious file uploads
• Data leakage risk: Files could potentially trick Claude into data exposure

Performance Comparison Matrix

Feature	Desktop	Web	Mobile
File Creation	✅	❌	❌
MCP Extensions	50% reliability	❌	❌
Local File Access	Text files only	Upload only	Limited
RAM Usage	400MB-1.5GB+	Browser tab level	Optimized
Installation Time	30min with extensions	Immediate	App Store standard
Voice Input	Slower than mobile	❌	Superior
Offline Capability	Conversation history only	❌	❌

Critical Failure Scenarios

Extension Failures

• Frequency: ~50% reliability rate
• Auto-update breakage: Configs corrupted during weekly updates
• GitHub timeout: Consistent failure on large repositories
• Calendar corruption: Event duplication requiring manual cleanup
• Screen capture crashes: Kernel panics on 4K displays

Resource Issues

• Memory consumption: Can exceed 1.5GB with active extensions
• Background persistence: Runs continuously even when closed
• Update frequency: Weekly auto-updates with potential config breakage

Cost Analysis

Subscription Requirements

• Free tier: 3 messages/day (insufficient for meaningful use)
• Pro requirement: $20/month for MCP extensions ($240/year)
• ROI threshold: Must justify cost vs. web version functionality

Time Investment

• Setup time: 10-30 minutes (best case) to 2 hours (problematic)
• Maintenance overhead: Weekly update troubleshooting
• Troubleshooting: Ongoing extension debugging requirements

Decision Criteria

Use Desktop When:

• Frequently transferring files between Claude and local system
• Performing regular data analysis requiring file outputs
• Need screen capture integration
• Have Max/Team/Enterprise subscription for file creation

Use Web Version When:

• Occasional Claude usage
• RAM constraints (systems <16GB)
• Minimal local file integration needs
• Avoiding maintenance overhead

Common Misconceptions

• "Offline capabilities" = conversation history browsing only, no actual AI functionality
• "4GB RAM minimum" = unusable in practice, 16GB required for reasonable performance
• "Seamless integration" = 50% extension reliability with regular breakage
• "Better than web" = marginal performance gains don't justify resource usage for most users

Migration Considerations

From Web to Desktop

• Prerequisites: Pro subscription for useful functionality
• Learning curve: Extension management and troubleshooting
• Hardware requirements: RAM upgrade potentially necessary

Enterprise Deployment

• Testing requirement: Pilot before organization-wide rollout
• Permission configuration: Pre-configure to avoid user confusion
• Support overhead: Plan for increased IT troubleshooting

Breaking Points

• 1000+ file repositories: GitHub integration fails consistently
• 4K monitor usage: Screen capture causes system crashes
• Memory-constrained systems: <16GB RAM results in poor experience
• Frequent auto-updates: Weekly update cycle breaks configurations
• Large data uploads: File creation feature may timeout on substantial datasets

Operational Intelligence Summary

Claude Desktop provides genuine value for users requiring local file integration and data analysis capabilities, particularly with the September 2025 file creation feature. However, the 70% extension reliability, significant RAM usage (400MB-1.5GB+), and $240/year Pro subscription requirement create a high barrier to entry. The desktop app excels for power users doing regular data work but offers minimal advantages over the web version for casual usage. Extension ecosystem improvements in 2025 reduced setup complexity from 2+ hours to 10-30 minutes, but ongoing maintenance overhead remains substantial due to weekly auto-updates and configuration fragility.
