Manus vs Devin

Manus is a general-purpose autonomous AI agent capable of multi-domain tasks including coding, research, and data analysis, while Devin is specifically engineered as an autonomous software engineer. Both can independently execute complex tasks but with different specialization levels.

Manus is designed as a broad autonomous agent that can handle software development alongside many other task types including research, document generation, and web browsing. Devin is purpose-built for software engineering, with specialized tooling for coding, testing, and deployment. The specialization gap matters significantly for teams with purely engineering needs.

Head-to-head comparison

Code structure

Devin

Manus

Manus can write code but its generalist design means it may not consistently produce code that follows engineering best practices or project conventions.

Devin

Devin is specialized for software engineering and produces more consistently structured code with better awareness of development patterns.

Security

Devin

Manus

Manus operates with broad system access across many task types, requiring careful permission configuration to prevent unintended data access.

Devin

Devin's security model is designed around software development contexts, with more targeted access controls for code repositories and development tools.

Speed of prototyping

Tie

Manus

Manus can rapidly execute multi-step tasks that combine research, planning, and code generation in a single autonomous workflow.

Devin

Devin is fast specifically for software engineering tasks, with specialized knowledge that reduces iteration time on coding challenges.

Backend/data layer

Devin

Manus

Manus can implement backend systems as part of broader task execution, though its generalist nature may produce less optimal data architecture.

Devin

Devin understands software architecture deeply and can design and implement well-structured backend systems with proper data modeling.

Deployment readiness

Devin

Manus

Manus can execute deployment-related tasks but its general-purpose design means deployment workflows need explicit instruction.

Devin

Devin has built-in understanding of deployment processes and can interact with CI/CD tools and cloud platforms more reliably.

Long-term maintainability

Devin

Manus

Manus-generated code may require more review and cleanup for long-term maintainability, as it lacks specialized software engineering knowledge.

Devin

Devin's software-specialized training produces more maintainable code with better adherence to engineering conventions and patterns.

Code quality

Devin produces higher-quality software engineering output due to its specialization in coding and development workflows. Manus is more versatile but the lack of deep software engineering specialization shows in code quality and consistency.

Security

Devin has more targeted security controls appropriate for software development contexts. Manus's broader capability set requires more careful permission management to prevent access beyond what is needed for coding tasks.

Which should you choose?

Choose Manus if...

Best for teams needing an autonomous agent that can handle diverse tasks beyond coding, including research, analysis, and document generation alongside development.

Frequently asked questions

Can Manus be restricted to only perform coding tasks?

Manus can be directed to focus on coding tasks through prompting, but its general-purpose design means it lacks Devin's specialized software engineering depth.

Does Devin integrate with popular version control systems?

Yes — Devin integrates with GitHub and can clone repositories, create branches, commit changes, and open pull requests as part of its workflow.
