Pros & cons
Factory AI
Pour
- +True end-to-end autonomy — Droid agent ships complete features without hand-holding
- +Native AGENTS.md adopter — fits modern repo conventions out of the box
- +Multi-agent coordination across linked repos for cross-service changes
Contre
- −Token-based pricing can spike on large refactors
- −Zed-first; JetBrains support newer, VS Code on roadmap
- −Less mature than Devin for very long-running autonomous sessions
GitHub Spark
Pour
- +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)
Contre
- −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
