Pros & cons
- +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
- −Framework, not a finished product — engineering effort to ship anything
- −Smaller community than LangChain / LlamaIndex
- −Cloud pricing not yet published — usage-based and opaque
- +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
- −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
