Pros & cons
Factory AI
メリット
- +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
デメリット
- −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
Fixie
メリット
- +Real multi-agent primitives — planner + workers + reviewer out of the box
- +Strong for internal-tool agents over your own data
- +Permissive license; auditable end-to-end
デメリット
- −Framework, not a finished product — engineering effort to ship anything
- −Smaller community than LangChain / LlamaIndex
- −Cloud pricing not yet published — usage-based and opaque
