Devin's External Dependencies

Devin focuses purely on code creation and doesn't include deployment capabilities. After Devin completes development work and creates pull requests, you need separate infrastructure for hosting and deployment. This separation follows traditional development patterns where code creation and deployment are distinct concerns.

For deployment, you'll need:

• Separate hosting services like AWS, Vercel, or Heroku
• CI/CD pipeline configuration
• Infrastructure management expertise
• Additional monthly costs for hosting
• DevOps knowledge or team support
