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
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
