• エンタープライズ（セルフホスト）(Enterprise - Self-Hosting): Devin is recommended. Devin’s Enterprise tier explicitly mentions “VPC deployment,” which typically allows for self-hosting or deployment within a private cloud environment, offering greater control and security for enterprise clients. While Windsurf also has an Enterprise tier, the self-hosting option is more clearly articulated for Devin.

Verdict

Devin and Windsurf represent divergent paths in the evolution of AI-assisted software development. Devin aims for a paradigm shift, positioning itself as an autonomous AI engineer capable of handling entire development projects. Its strengths lie in its ability to plan, execute multi-step tasks independently, and integrate deeply into project workflows with features like automated documentation and codebase Q&A. This makes it a powerful tool for tackling complex, end-to-end engineering challenges where full automation is desired.

Windsurf, conversely, focuses on augmenting existing developer workflows with a suite of intelligent tools. Its strengths lie in providing highly flexible AI code completion, powerful codebase search, real-time collaboration, and the unique ability to integrate custom AI models. The inclusion of a free tier and more affordable paid plans makes it an accessible option for a broader range of users, from individual developers to small and medium-sized teams looking to boost productivity without a complete overhaul of their existing toolchains.

The choice between Devin and Windsurf hinges on specific project requirements, team structure, and budget. For organizations seeking a fully autonomous AI engineering solution for complex tasks and willing to invest in that capability, Devin presents a compelling, albeit more expensive, option. For developers and teams prioritizing cost-effectiveness, flexibility in tool integration, and enhanced productivity through AI code assistance and search within their current environments, Windsurf offers a robust and accessible solution. Given the data provided, which shows zero feature overlap, neither tool is a direct substitute for the other; they cater to different but complementary needs in the AI development ecosystem.
