Amazon has been promoting its in-house AI coding tool Kiro over third-party services like Claude Code from Anthropic, one of its largest investors. This policy change has sparked criticism among employees who have to sell Claude Code on Amazon’s platform. Employees argue that they can’t credibly promote a product they are not permitted to use themselves in official work. The move highlights the complexity of Amazon’s relationship with Anthropic and raises questions about why Amazon is pushing its own tool over a partner’s competing technology. Despite criticism, Amazon claims it has seen improvements in efficiency and delivery from Kiro, which it wants all internal employees to use for faster customer growth.
