Pros & cons
Amazon Q Developer
Pros: Only major coding agent with first-class AWS-service context (CloudWatch, IAM, CloudFormation) baked in; AWS procurement is already in place at most enterprises.
Cons: AWS-centric — limited value off-AWS; less polished editing UX than Cursor / Windsurf.
GitHub Copilot (Agent Mode)
Pros: Largest paid-seat base in the category; deepest IDE coverage (VS, VS Code, JetBrains, Neovim); first-mover network effect.
Cons: GitHub-centric; product surface has fragmented (Copilot vs Workspace vs Agent Mode vs Spaces); slower to ship newer agentic patterns than startups.
