Amazon Employees Revolt Against In-House AI Coding Tool

Around 1,500 Amazon staffers are pushing back against mandate to use Kiro, demanding Claude Code instead.

Amazon Employees Revolt Against In-House AI Coding Tool

Amazon's got a rebellion brewing in its engineering ranks. The company is pushing its homegrown AI coding assistant Kiro for production code, and developers aren't having it.

Roughly 1,500 employees have signed on to advocate for Anthropic's Claude Code instead of the in-house alternative. Internal messages reveal growing criticism of the mandate to prioritize Kiro over third-party tools.

The pushback highlights a familiar tension in Big Tech: build versus buy. Amazon clearly wants to keep AI development in-house, but its own engineers apparently think the competition builds better tools.

When your workforce of coders actively campaigns against your coding assistant, that's not a great sign. The internal revolt suggests Kiro may not be ready for prime time—at least not in the eyes of the people actually writing the code.
