Pros & cons
Aider
メリット
- +Best-in-class pair-programming flow in the terminal
- +Repo map mode handles surprisingly large codebases
- +Provider-agnostic — bring any LLM that supports tool use
デメリット
- −No UI — pure CLI is a deal-breaker for some teams
- −Token spend at heavy use rivals a paid SaaS plan
- −Less polished autonomy than Devin or Replit Agent
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
