Amazon Promotes In-House AI Coding Tool Kiro Over Competitors
11/25/2025, 12:28:57 PM
Internal Directive to Favor Kiro
Amazon has directed its engineers to prioritize the use of its proprietary AI coding tool, Kiro, over third-party alternatives. An internal memo, reviewed by Reuters, indicates that while existing tools will still be supported, the company does not plan to endorse additional third-party AI development tools. This guidance effectively discourages the use of popular coding tools such as OpenAI's Codex, Anthropic's Claude Code, and Cursor's offerings.
Kiro, launched in July 2025, is designed to facilitate the creation of websites and applications using plain English commands. The memo, signed by Peter DeSantis and Dave Treadwell, emphasizes the importance of employee feedback in enhancing Kiro's capabilities. The directive comes as Amazon seeks to strengthen its position in the competitive AI landscape, where rivals like OpenAI and Google have made significant advancements.
Amazon's Competitive Landscape
Despite Amazon's substantial investments in AI, including approximately $8 billion in Anthropic and a seven-year, $38 billion deal with OpenAI for cloud services, the company has faced criticism for lagging behind its competitors in AI tool development. The internal memo reflects a strategic shift aimed at consolidating Amazon's resources around Kiro, which has recently expanded its global availability and introduced new features.
Criticism of the Directive
The decision to limit the use of third-party tools has raised concerns among some engineers. Critics argue that restricting access to established coding tools could hinder innovation and reduce the overall effectiveness of development teams. The memo's directive to avoid tools like Codex and Claude Code, which have been widely adopted in the industry, may lead to frustration among employees accustomed to using these resources.
Official Statements & Responses
An Amazon spokesperson confirmed the existence of the memo but did not provide further details on the rationale behind the directive. The memo's tone suggests a commitment to improving Kiro through employee collaboration, stating, "To make these experiences truly exceptional, we need your help."
Conflicting Reports & Gaps
There have been conflicting reports regarding the status of third-party tools within Amazon. For instance, Claude Code was previously designated as "Do Not Use," a designation that was later reversed following media inquiries. This inconsistency raises questions about the company's internal policies and their implementation.
What's Next for Kiro?
As Amazon continues to develop Kiro, the company is likely to focus on enhancing its features and capabilities to compete effectively in the AI coding space. The internal push for Kiro may also lead to further scrutiny of Amazon's relationships with third-party AI developers and the broader implications for the tech industry.
