Pros & cons
GitHub Spark
メリット
- +Native GitHub integration — apps deploy with one click
- +Bundled with Pro+ subscription — no separate billing relationship
- +Best for "personal apps" use case (Slack tools, side-project utilities)
デメリット
- −Newer than Lovable/Bolt — fewer templates and patterns
- −Less flexible than dedicated builders for production apps
- −Limited to specific app shapes — not a general-purpose builder yet
Replit Agent
メリット
- +Ships full deployed apps from one prompt — fastest 0-to-production agent
- +Cloud-native: no local setup, no env hell, instant collaboration
- +Strong for non-engineers prototyping ideas
デメリット
- −Tied to Replit cloud — bringing the code home requires manual export
- −Less control over architectural choices than IDE-native agents
- −Effort-point math at heavy use can surprise
