  • Excellent at research and data gathering
  • Results delivered asynchronously — no babysitting needed

Cons

  • Credits consumed quickly on complex tasks (500–900 per task)
  • No credit rollover — unused credits expire monthly
  • No pre-task cost estimates
  • Mid-task depletion stops execution with no partial refund

Devin

Pros

  • Fully autonomous — plans, codes, debugs, deploys
  • Handles complex multi-step engineering tasks
  • Integrates with GitHub, Slack, Jira
  • Pay-as-you-go from just $20

Cons

  • No free tier
  • ACU costs add up on long tasks
  • Can go off-track on ambiguous requirements
  • Less interactive than Cursor/Copilot for pair-coding

Verdict

Devin is purpose-built for software engineering with deep codebase understanding, while Manus is a general-purpose agent that handles research, browsing, and diverse tasks. Devin for dedicated coding assistance, Manus for broad autonomous task completion.
