Continue vs Cody

Continue is best for developers who want full control over models (including local) and a single open-source assistant across IDEs. Cody excels when you use Sourcegraph and need deep codebase context and enterprise features. Both support VS Code and JetBrains.

SWE-agent vs Devin

SWE-agent is best for automated, benchmark-grade GitHub issue fixing with open-source control and your choice of LLM. Devin is best for full autonomous development with its own environment and broad task coverage—at a premium price. Choose SWE-agent for focused, reproducible fixes; Devin for end-to-end autonomous engineering.
