Anthropic acquires developer tools startup Stainless

Anthropic has acquired Stainless, a New York-based developer tools startup used by major technology companies including OpenAI, Google, and Cloudflare.

As part of the acquisition, Stainless will wind down all hosted products. The deal reflects Anthropic's strategy to strengthen its infrastructure and tooling capabilities as competition intensifies in the artificial intelligence sector.

Stainless provided development platforms widely adopted across the tech industry. The acquisition allows Anthropic to integrate these capabilities into its own AI development ecosystem.
