The Decision Engine

The 6-Question Assessment

Before evaluating any platform, answer these six questions. They determine everything else.

1What Is Your Deployment Constraint?

Constraint TypeBest Platform CategoryTrade-off
Data cannot leave premisesSelf-hosted open sourceRequires technical infrastructure
No engineering resourcesManaged cloud servicesVendor lock-in, ongoing costs
Must integrate with existing stackEcosystem-native platformsLearning curve
Budget under $500/monthOpen source + self-hostedTime investment required
Speed to deployment criticalLow-code managed servicesCustomization limits

2What Is Your Technical Reality?

Level 1: Business Users Only

Can use web interfaces. Cannot write code.

→ Match: Low-code platforms

Level 2: Technical Staff

Can modify config files. Basic API understanding.

→ Match: Low-code + customization

Level 3: Developers

Python/JS proficiency. API integration experience.

→ Match: Open-source platforms

Level 4: ML/AI Team

Model fine-tuning. Infrastructure at scale.

→ Match: Framework platforms
