💡 Our Take
Choose Devin if you need an autonomous agent that can take long-running tickets, work with existing enterprise codebases, and deploy via your CI/CD pipeline. Choose bolt.new if you want fast in-browser prototyping of full-stack web apps from a prompt — bolt is optimized for greenfield builds with instant previews, while Devin is optimized for delegated work inside established repositories with complex dependencies and existing conventions.
Bolt.new - Pros & Cons
Pros
- ✓Zero local setup — everything runs in the browser via WebContainer
- ✓Auto-routes between Claude, GPT, and Gemini for best-fit model per task
- ✓One-click Netlify deploy plus GitHub sync keeps output real, not throwaway
- ✓First-class Supabase and Firebase wiring for auth and database in minutes
- ✓Mobile apps let you build and edit from an iPhone or Android
Cons
- ✗Credit-based pricing burns fast on large projects and error-heavy iterations
- ✗Only supports web/Node stacks — no native iOS, Android, or Python backends
- ✗No MCP server integration; extending with custom tools requires code
- ✗Generated code quality can drift on projects over a few thousand LOC
Devin (Cognition) - Pros & Cons
Pros
- ✓End-to-end autonomy: plans, codes, tests, and deploys without continuous human prompting, unlike inline assistants such as Copilot or Cursor
- ✓Self-serve pricing starts at $20/month using ACU (Autonomous Compute Units), a 25x reduction from the original $500/month enterprise tier
- ✓Operates a full sandboxed environment with code editor, terminal, and browser — enabling real research, package installation, and deployment workflows
- ✓Proven on enterprise-scale work including COBOL modernization at Fortune 500 companies and a large-scale migration at Nubank
- ✓Built by a high-density founding team with 10 IOI gold medals and senior engineers from Cursor, Scale AI, Google DeepMind, Waymo, and Modal
- ✓Now integrated with Windsurf IDE (acquired by Cognition) and supports a Devin-for-Terminal hand-off workflow that starts local and resumes in the cloud
Cons
- ✗ACU-based pricing can become unpredictable for long-running tasks compared to flat-rate competitors like Copilot ($10/month) or Cursor ($20/month)
- ✗Autonomous decisions may diverge from team coding standards or architectural conventions without careful guardrails
- ✗Less interactive than IDE-native assistants — best for delegated tasks, not pair-programming or real-time editing
- ✗Enterprise features and dedicated support are gated behind Team ($200/month per seat) and custom Enterprise plans
- ✗Newer than established tools, so long-term code quality and maintenance patterns are still being validated in production deployments
