Who should buy this

Devin

Best for
  • Engineering team facing large-scale migration / refactor work (codebase modernization, framework upgrades)
  • VP Eng wanting to scale capacity without proportional headcount growth
  • Senior engineer offloading well-scoped tasks (test coverage, dependency upgrades, format consistency)
Not ideal for
  • Solo devs preferring augmented-IDE workflows (Cursor / Copilot fit better)
  • Teams without clear task scoping (Devin needs well-defined work to thrive)
Realistic monthly cost

Solo dev: free (Review + DeepWiki) or $20/mo Pro. Power user: $200/mo Max. Team: $80/seat/mo. Enterprise: custom contracts (typically $50-300K+/yr).

DeepSeek

Best for
  • Cost-conscious team handling token-heavy workloads
  • Developer or org needing self-hosted, on-prem, or air-gapped deployment
  • Researcher or open-source maintainer building on permissive-weight models
Not ideal for
  • Org with strict data-sovereignty rules excluding Chinese-origin platforms
  • Buyers requiring SOC 2 / ISO 27001 from the API provider (no public attestations)
Realistic monthly cost

Pay-as-you-go API: ~$3-50/mo for individual developer use. Self-hosted: GPU compute cost only (no license fees).
