Amazon Shifts Engineers to In-House AI Tool Kiro, Drops Support for Rival Coding Platforms
Amazon has directed its engineering teams to abandon third-party AI coding tools in favor of Kiro, its proprietary code-generation service. The mandate appeared in an internal memo circulated Monday, coinciding with a 2.53% share price rise to $226.28.
Kiro represents Amazon's strategic pivot toward controlled AI development. Launched in July with Anthropic's technical assistance—though notably not using Claude Code—the platform allows engineers to generate code through natural language prompts rather than manual scripting.
The policy shift comes as Amazon expands Kiro's global availability and adds new features. Two senior executives—one from AWS and another from eCommerce—signed the memo positioning Kiro as the default development tool, citing accelerated improvement cycles through concentrated internal usage.
