Technical Specifications & Critical Limitations

Performance Characteristics

Metric	Typical Range	Critical Threshold
Web App Load Times	3-10 seconds	15+ seconds (user abandonment)
Mobile App Load Times	2-8 seconds	10+ seconds (critical failure)
Database Query Performance	200-400 Workload Units per search	500+ WUs (cost explosion)
Repeating Group Performance	Works up to 500 items	Breaks down at 1000+ items
Concurrent Users (Growth Plan)	~1000 users manageable	Performance degrades beyond 2000

Database Limitations

Capabilities:

• Simple relationships (one-to-many)
• Basic CRUD operations
• Privacy rules (field-level security)
• File storage via AWS S3

Critical Breaking Points:

• Complex joins: Not supported
• Many-to-many relationships: Becomes complicated
• SQL queries: Impossible (locked to visual query builder)
• Database optimization: No indexing control
• Aggregations: Multiple search steps required

Workflow System Constraints

Functional Limits:

• 10-15 workflows: Manageable complexity
• 50+ workflows: Dependency tracking becomes impossible
• Nested conditions: Visual spaghetti after 5-10 levels deep
• Debugging: No stack traces, no real logs

Critical Failure Modes:

• Silent privacy rule failures (no error messages)
• Workflow loops causing WU spikes (400% overnight increases documented)
• API integration failures with generic error messages
• Conditional logic breaks with no clear indication of cause

Cost Structure & Resource Requirements

Pricing Reality vs Marketing

Plan	Advertised Price	Real Production Cost	Breaking Point
Personal	$29/month	$29-100/month	100 active users
Growth	$134/month	$200-700/month	1000 active users
Mobile Add-on	$32/month	$100-300/month	During development (build limits)

Workload Unit (WU) Economics

Standard Operations:

• Simple page load: 20-80 WUs
• Database search: 200-400 WUs
• Complex workflow: 500+ WUs
• Real-time features: Exponential WU consumption

Cost Explosion Scenarios:

• Adding repeating group filters: 400% WU spike documented
• Real-time messaging implementation: $400-700/month in overages
• Search functionality on 500+ items: 15-25 second load times

Mobile Development Costs

Base Requirements:

• Mobile plans: $32/month minimum
• Combined web + mobile: $42/month minimum
• Build limits: Monthly caps on compilation/deployment

Hidden Costs:

• Build overages: $60-80 during debugging cycles
• iOS submission rejections: 3-4 builds per fix attempt
• Plugin compatibility issues: Additional build consumption

Development Timeline & Complexity

Learning Curve Reality

Experience Level	Time to Competency	Breaking Point
Non-technical	3-8 months	Month 3 (debugging visual spaghetti)
Technical background	2-3 weeks basic, 3-6 months advanced	Complex business logic implementation
First functional app	2-3 weeks	User authentication setup
Production-ready app	3-6 months	Performance optimization phase

Development Process Reality

Phase 1: Basic Setup (1-2 weeks)

• Page mockups: Works well for basic layouts
• Data type setup: Straightforward until many-to-many relationships
• Simple workflows: Functions as expected

Phase 2: Business Logic (2-8 weeks)

• Complex workflows: Becomes visual maze
• User authentication: Works when configured correctly
• API integrations: Debugging becomes archaeological work

Phase 3: Performance & Debugging (Ongoing)

• Load time optimization: Impossible (no control over infrastructure)
• Workflow debugging: Hours to fix issues that would take minutes in code
• Privacy rule configuration: Silent failures common

Mobile Development Assessment

Native App Compilation (2025 Feature)

Technical Implementation:

• Compilation Target: React Native 0.72+
• Performance: Significantly better than web versions
• App Store Deployment: Direct publishing to iOS/Android stores
• Native Features: Camera, GPS, push notifications, biometric auth
• Offline Capability: Local storage with sync

Critical Limitations:

• No React Native Source Access: Cannot write custom components
• Build Limits: Monthly compilation caps
• Debugging Constraints: Limited on-device debugging
• iOS Requirements: Mac required for iOS simulator testing

Performance Comparison:

• Web app load times: 3-10 seconds
• Mobile app load times: Native speeds (sub-2 seconds)
• Battery efficiency: React Native optimized
• Platform optimization: iOS/Android specific

AI Features Evaluation

AI App Generation

Functional Scope:

• Simple CRUD apps: 30 minutes time savings
• Todo apps/contact directories: Generates working prototypes
• Complex applications: Creates more problems than solutions

Implementation Reality:

• Output quality: Requires significant cleanup
• Component suggestions: Often irrelevant recommendations
• Workflow optimization: Catches obvious issues only
• Database design: Reasonable schemas for simple cases

Decision Criteria: Use for basic prototypes only, rebuild from scratch for production

Competitive Analysis Matrix

Platform	Use Case	Performance	Cost	Code Export	Mobile	Learning Curve
Bubble	Full-stack web/mobile	Poor (3-15s)	$32-700+/month	❌ Locked in	✅ React Native	Steep (3-8 months)
Webflow	Marketing sites	Fast	$14/month	✅ Clean export	❌ Web only	Medium
Adalo	Mobile apps	Good native	$45/month per app	❌ Locked in	✅ True native	Easy
Glide	Simple data apps	Very fast	$25/month per user	❌ Locked in	✅ PWA + native	Very easy
OutSystems	Enterprise	Fast	$$$ Enterprise	✅ You own code	✅ Full native	Brutally steep

Critical Warnings & Breaking Points

Vendor Lock-in Consequences

No Code Export: Application logic permanently trapped in platform
Data Export: Only data can be extracted, not application structure
Platform Dependency: Price increases or service termination = complete rebuild
Migration Impossibility: No path to convert Bubble app to standard code

• Plugin compatibility issues
• iOS version-specific crashes

Debugging Challenges:

• No stack traces for workflow failures
• Generic error messages for privacy violations
• Plugin failures with no detailed logs
• Build failures with cryptic messages
